Next Steps? (Research) - 08/21/05
Hi Crew!
<<Good morning>>
Thanks for the great site! I am relatively new to this hobby and have found SO
MUCH wonderful information- a big help so far.
<<Is why we are here...>>
Sorry in advance for this long email, but this is my one question to make sure I
am doing okay and finalize (if that ever occurs with a marine tank) my system
for now.
<<Alrighty>>
I have a 50 g (30-in L) marine FOWLR set-up that was started about 2 months ago
with 40 lb live sand. It now has 30 lb live rock as well (added with about 20
lbs at start and then a few 5 lb-each additions). Some of the initial live rock
and a scoop of sand came from my nephew's tank that is over 2-years old and
quite healthy, so I think I had a pretty good start.
<<Always a good way to go.>>
Also, one of his rocks had a nice colony of polyps on it, as well as some light
green sponge (he says he had that identified as such) that are both doing well.
<<Ahh, freebies <G> >>
I also am noting some tube worms and other live rock critters.
Quite cool!
<<Yes! All good...>>
I have a canister pump (Cascade 1000), compact fluorescent it's (30-in, 1-65W
actinic 03 blue and 1-65W 10,000 K daylight with reflectors). As a former
chemist, I have been testing, testing, testing!
<<Good on ya!>>
My readings have been: Nitrite- always 0, no spike ever; ammonia- ditto;
nitrate- 0 for the first month, and now a small bit, < 5 mg/L; alkalinity (KH)-
180 to 300 ppm (I have been adding some buffer of late due to the calcium, which
I read about on your site) <<Mmm, would work to keep alkalinity in the 150-180
ppm range>>; calcium- started out okay, but after adding cleaning crew and
protein skimmer at the 1-month time point, it began to drop, so I am
supplementing and keeping it >330 ppm, aiming for at least 375 ppm.
<<In this system, anything above 330 will do just fine.>>
Ditto, iodine (protein skimmer, I think) that I have just started testing, was
quite low, so I am adding some now and will watch that.
<<Iodine can be/is very beneficial, and very easy to abuse. Please follow
directions carefully.>>
The pH seems to vary depending on the test type. I have 3 different
manufacturers' test kits and get 3 different answers on the same sample, so,
with extrapolation, it started out around 7.8 to 8.0 and I have been slowing
raising to about 8.1 to 8.3. It's difficult with these variations in test kits
to give a sure number, but all I can say here is that the pH has been stable
overall.
<<Stability is key...I would choose one kit and stay with it for that
reason. Better yet, purchase an electronic pH meter. Small expense compared to
what you have spent/will spend on this system.>>
As noted, I added 14 Astrea, about 20 Cerith snails, and a dozen blue-legged
(tiny guys) <<won't stay "tiny">> hermit crabs (over several weeks' time as the
algae began to bloom). Early on (probably too early, only about 1-week in
<<yikes>>, but then, I hadn't found your site yet), I added 4 green Chromis (sp.
Viridis; 1 at 1.5 in, the other 3 at ~1 or smaller in). The fish did very well
and I tested every day and no change was noted in the readings so, after several
weeks, I added two clown fishes that I got from different stores (1 at 1.5 in, 1
considerably smaller) and they have also done well, with no changes in water
conditions.
<<Very well...but I hope this isn't leading up to an anemone purchase?>>
Also, several weeks ago, I added a cleaner shrimp and 2 peppermint shrimp, and
just added a sand sifting goby (orange-striped). I like him a lot!
<<Very cool/interesting to watch, aren't they.>>
My questions are about the next steps and optimizing my system. I plan to get
some mushrooms and a xenia and then the fish.
<<Careful, you're about "full up" on fish in this tank.>>
First, how much more live rock should I add? Some sites have said 1-1.5 lb per g
live rock AND live sand, while some only seem to calculate based on the rock and
I hear people say "the more the merrier".
<<Have to say I've come to disagree with the rock calculations/most opinions. I
don't think you (or anybody) needs to fill your tank with rock to be
successful. Quite the reverse actually, as too much rock inhibits water flow
and traps/hides detritus. I find less rock arranged in a very "open" fashion
looks better, serves the system better (as just mentioned), and gives those
wonderful fishes (and corals too) some room to swim and grow! At 40lbs. you
probably already have plenty of rock in this tank, probably even too much
(depending on the rock), in my opinion.>>
And, with respect to my Chromis, I got the 4 because I initially read that they
should be in a group of 4 or more, and this was a group that was together at the
LFS; but, now I am reading that 3 would be a better school size
(odd-numbered). I do see some chasing, but now signs of anything serious like
appetite problems or nipped fins. For other fish, I have really taken to the
pajama fish, but I have read that they should be in a group of 3 or as a mated
pair.
<<Sphaeramia nematoptera (Pajama Cardinal) generally do very well in
groups. But in this size system, with the fish you already have, I would
probably keep it to two.>>
The LFS has a single one, and now, since doing my reading, I am sad every time I
see this guy alone. But, in my system, I am thinking that 2 pajama fish would
be the max, so I need to get a mated pair?
<<Ahh, great minds, eh... A mated pair would be nice if you can find such, but
two of any gender will likely do fine.>>
And, would they work well with the Chromis, or would it be too many fish (or the
Chromis too active for them) and should I take the Chromis back to the LFS?
<<I've kept both species together in the past (though not in quite as small a
tank) with no problem. The Chromis can tend to out compete the cardinals for
food, but any direct aggression is usually conspecific. But even so, unless you
really like the Chromis I would remove at least two (if not all) and return them
to the LFS. Then you could easily go with three cardinals <G>.>>
If I were to take the Chromis back, what other fish would you recommend. I am
looking to put in fish that play different roles in the over all system and,
knowing that the Chromis and clowns are both damsels, I have wondered if I
should keep both anyway (the clowns win, sorry guys).
<<Yes, and the clowns can become very aggressive. If you take the Chromis out
and get two or three cardinals to go with the clowns and the goby, I might
consider one of the dart fish for a bit of color/diversity. Do be aware though,
your clowns will eventually determine what fish you can have in this
tank. Don't underestimate their ability to become bullies, and I would expect
them to eventually "rule" this entire system.>>
The only down side is that the large Chromis keeps the cleaner shrimp busy and I
would want a fish that would visit my shrimp. Any other suggestions?
<<Ahh...ok...remove all the Chromis, add only two cardinals, and look in to one
of the Centropyge angel species.>>
Well, that's it for now. Thanks to Bob and Anthony for the great books!
DeAnn
<<Regards, EricR>>
Aquarium pic
hey guys.. someone finally came up with a camera that could piece photos
together in order to obtain a panoramic picture of my tank so that
everyone
could have a better idea of it when I talk about it..
so here's to the hard work and effort that Alex and I have put into this
tank,
and thanks to all the people who have contributed and helped with it. :)

New Tank Replacement/Addition of LR
>Greetings & Salutations,
>>Hello to you as well!
>I’ve stumbled upon your site – similar to stumbling into my husband’s
hobby. Recently our saltwater aquarium developed a small
leak. We decided to replace the tank before a disaster occurred (I
think we just created a new one!?). Our old system consisted of a 42
gallon tank, 4 VHO lamps, 1 wet/dry filter with pre-filter, a 3” x 21”
protein skimmer, Mag 350 filter, and a ¾” Quiet One pump. What a
mess. Anyhow, we now have a new 55 gallon tank and have transferred
our existing LR and residents, and decided to add additional LR. So,
not being the sharpest
knives in the drawer, we purchased and “added” 32 lbs of pre-cured LR.
>>Uh oh...
>Well, needless to say, we have been dealing with some ammonia
spikes. Currently, my husband is doing a 20% water change
daily. Would purchasing a cleaner kit consisting of hermit crabs,
snails, etc. be of help? Or should we wait?
>>Wait to add the inverts, they won't do the kind of cleaning you're
thinking of. They'll surely suffer for the ammonia, which is going to
lead to nitrite and nitrate spikes, as well. I would do several 50%
water changes, you're in the process of inadvertently curing your live rock in
your main system.
>I’ve also read some of your articles regarding Aiptasia and peppermint
shrimp. I have thought of adding 4-5 of these in the near future as
we have some glass anemones on our old rock. I’ve also read that
Copper Banded Butterfly fish are natural predators for Aiptasia.
>>Generally, but not always a given. Wait for the nitrification
cycle to settle back down before adding more inverts,
though. Oh! Is your skimmer producing really nasty
skimmate? This is what we want, for it to be absolutely foul, this
way you can be certain it's doing its job.
>Cleaner kits are also available for the
substrate. Wow! I’m so amazed at all the information
available. Your site is awesome. I’m dumbfounded that we
have stumbled along for years (seven years with old tank) with a few books and
information obtained from LFS.
>>Well...so am I! ;)
>Our local family residents consist of: 2 yellow-tailed damsels, 1 goby,
mushrooms, bubble anemone, couple of hermit crabs and
George (boxfish/cowfish). I’m really worried about losing our small
community, especially George. What a neat fish! He comes
to visit whenever your near the aquarium and I can practically hand feed
him. I transgress – sorry. So, will adding a “cleaner
kit” help with the LR situation?
>>Read above. What might be of long-term help would be to set
up a refugium. I say get that old tank repaired (do it yourself if
you like, it's a bit of a pain in terms of labor but it's easy-peasy to figure
out) and make it a refugium in which you can set up a deep sand bed (DSB) and
establish some macroalgae to help with nutrient export. Everyone will
be happier for it. However, for NOW, do those big water changes to
get a handle on the curing issues--this will go a long way towards ensuring
everyone in the family can weather this little storm.
>If not, how long do I need to wait before adding the various
tank cleaners (substrate, algae, and Aiptasia)?
>>Are you saying you're going to *add* Aiptasia? If so, please
don't. There are other things that will do whatever it is you want
the Aiptasia to do. I would strongly recommend that you add nothing
else to the tank until you get all readings down to zero, nitrates TRACE at most
(a DSB will denitrify, thus bringing nitrates to zero readings, but it takes a
while for a DSB to become well established).
>Any feedback will be greatly appreciated, in hopes that this old rusty blade
can be sharpened. Thanks in advance :-) Rmac
>>LOL!! Reminds me of a really good Soundgarden song that
Johnny Cash covered, "Rusty Cage". anyway, that's what I would do--lots of
bigger water changes, ensure the skimmer is giving the foulest skimmate
possible, create the refugium (lots of info on site as well), and add your
clean-up crew once everything else is sorted. Good
luck! Marina
Miscellaneous Marine questions 3/27/03
Anthony, thanks for the thorough response.
<always welcome Joe>
Just to follow up. With my quarantine tank I have my fish in there
with copper due to an ich outbreak. It has been 3 weeks and I have 3
to go ( 6 week fallow period in main tank). I have no fish left in
the tank, if I was to crank the heat to say 90 would this kill off the ich
parasites quicker,
<no guarantee and likely to kill far more good things than bad>
I'd love to move the fish back sooner as these are cramped
quarters in my quarantine??? I thought I had read somewhere on your
site that one should rinse out all nets in a special chemical if treating
copper/ich and using same net for main tank. Do I need like 6
different nets for different applications or if I just rinse in fresh water and
let them dry off does this work ok???
<mild bleach solution, a good rinse and then air dry is sufficient/better>
I have been putting in kalkwasser recently and just wanted to check that what
I'm doing is ok. I mix 1/2 a teaspoon of calcium hydroxide in a
gallon of water, stir it and put a lid on it. At night before I go to
bed and lights are off I dump the water
(not the excess powder) into the sump,
<all good to this point... but do test to know your daily need for calcium
(evidenced by a drop over x days without) and calculate how much Kalk solution
it takes to meet that demand>
I then refill it with freshwater (don't add anymore powder - until its all
dissolved)
<mistake here if using tap water. Impurities are precipitated in Kalk
solution and remain in residue. Refine your technique/amount of Kalk to a
minimum and discard the small precipitate after every use. Using purified water
for this is better>
and let it sit till next night. 1) Sound ok??? 2) Once
I get it to 400 level, should it stay there for a while (this system is a bit of
a pain).
<not sure what you mean by "stay"... the system is always in
flux... the demand for minerals like calcium is ever present. It will drop
slowly daily... hence the need to dose small amounts of supplements daily or
several times weekly (regular water changes too). Consistency is crucial to
finesse a beautiful tank>>
Last question, is a colt coral for a beginner, int., or advanced aquarist,
anything special they need???
<reasonably hardy... but rather aggressive and fares better if introduced
into a mature tank that has healthy diatom and algae growth (eats some phyto).
Deep sand beds and refugiums bode well for this coral... but bare-bottomed
Berlin style tanks do not. Best regards, Anthony>
Reef tank husbandry and new corals 3/22/03
Good day WWMCrew.
<cheers>
I have purchased some corals from FFExpress that are to arrive this Saturday. I
have read many faqs and articles on WWM, so I do
know some things about corals. This will be my first attempt at them. Here are
the specs on my tank:
75 Gallons
75 lbs Fiji live rock
75 lbs Aragonite
20% water change monthly
Aqua Clear Aquatics wet/dry with built in venturi/downdraft skimmer and overflow
(bioballs removed)
260 watt JBJ Power Compact (4 65 watt bulbs, 2 10,000K daylight and 2
7,100 K Blue) Sander model ozonizer (25mg/h) with air dryer connected to the
venturi line, injecting ozone directly into the skimmer activated carbon in the
sump (changed monthly) 1 Powersweep 228 powerhead ( placed in back
corner ) 2 Aqua Clear 4000 powerheads ( facing each other ) I have a power strip
that is also a wave timer (can't remember name) so that the two Aqua Clears
create alternating currents ( and to provide a random
current )
<your hardware is fine... you may need more live rock if you expect to have a
moderate bio-load of fed fishes and corals... and the water change % is modest
even with an awesome skimmer. To be honest... its rather weak. Weekly water
changes are better than monthly... but if you prefer monthly... you'll likely
need to do a bigger exchange. Stocking levels will have a strong influence on
this as well as feeding regime>
Ammonia - 0
Nitrite - 0
Nitrate - 5 ppm
alkalinity - 3.5 mEq
ph - 8.4
temp - 82
calcium - 450 ppm
<all great... and be mindful not to push the Ca any/too much higher. A 400ppm
ballpark is stable and good/safe enough>
I currently have the following tank inhabitants:
Hawaiian Sailfin Tang
Pair of Tomato clowns
Scooter Blenny
Banggai Cardinal
many blue leg hermits and scarlet reef hermits
4 fighting conchs
many Turbos and Astrea snails
Green Serpent
<Yikes... a beautiful starfish, but if it is indeed Ophioderma incrassata
(Green Brittle Starfish), then it is a fish and invertebrate predator in time.
One of the only non-reef safe serpent stars!>
Feather Duster
Here are the corals I have ordered:
Toadstool Mushroom Leather (Sarcophyton sp.)
Tree Coral ( Paralemnalia sp.)
Thin Finger Leather ( Sinularia sp.)
Green Fluorescent Mushroom ( Actinodiscus sp.)
Green Button Polyps ( Palythoa sp.)
Do you see any potential chemical warfare between these species?
<there is always chemical warfare between cnidarians. You have
done a very good job of focusing on one group (soft corals) and will have a much
easier time with husbandry for it. All good choices. Quite reasonable>
Should I keep them at a good distance?
<6-10" apart minimum>
Do you see any potential compatibility issues
with the present livestock and the future?
<nothing out of the ordinary>
I appreciate any insight. P.S. I really find this sight as a great tool for all
aquarists. Anyone who cares about their aquatic life should really visit.
<thanks kindly... do tell friends/other aquarists about us :)>
I know I have saved myself a lot of time, money , and effort by reading the faqs
and articles here. I'm sure my current livestock and future livestock will
appreciate it too. Thanks, Charlie
<best regards, Anthony>
Parasite Identification and mud 3/19/03
First, I want to say thank you for all of the invaluable information I have
found in your archives.
<thanks kindly>
I am relatively new to the hobby (a little over a year) and have been extremely
frustrated at times with my "trouble-free" EcoSystem Aquarium. I've
gotten a lot more answers from
your website than from my dealer or the people at Ecosystem.
<I personally am not a big fan of the system for most applications... but it
can be very useful>
Two things:
I have a purple Firefish that has a bizarre parasite that I can't
identify. At first I thought it was coming out of his gill, but it is
directly behind the gill, coming out of the fish's body. It looks
almost like an extra fin (transparent), or a fly's wing, and it has a distinct
curly pattern, almost like a stretched-out telephone cord.
<odd... and doesn't sound like a large parasite (without seeing a pic/fish),
rather a growth>
It doesn't seem to bother him, and since I have been treating my tank with
Chem-Marin's Stop Parasite the curly pattern has lightened from its original
brown, but it still won't fall off.
<I personally think that product is weak at best>
Any idea what that is?
<catch the fish (early morning perhaps for better chance) and isolate it in a
QT tank. A freshwater dip will easily drop this "thing" if it is even
a parasite. Else, we can use the isolation period to treat it as a growth>
Also, in researching wetwebmedia.com to figure out what that thing is, I have
identified something else in my tank as "spaghetti worms". I
have tons of them. Are they harmful, and if so how do I get rid of
them?
<please encourage them! They are wonderful detritivores (scavengers)...
harmless too. Fish love to eat them as well. They are completely safe>
Thank you so much. Rebecca L. Dishman
<kind regards, my friend. Anthony>
Re: Do I need to start over again?
Thanks for the reply...
>>Glad I could help you, Cindy.
The reason I bought the mega lights is because I had a lighting problem with the
35 g tank. I wanted to "buy once" and hopefully in the future include
some mushrooms or moderate light corals. Guess I didn't think about it causing
other problems.
>>If we can get your nutrient export issues under control, and at least
get some macro-algae in there to help (either in a refugium or in the main
display) then the lights will serve you that purpose well.
The tomato clown and hawk fish were the only livestock transferred over from the
35 g. The others have been additions once I felt the tank had cycled. (this is
when I got the ick problem) and then I bought the cleaner shrimp.
>>Ok, they should be no problem in a 75gal tank. However, as I
understand it you didn't quarantine them before adding to the display. There's
your problem, and once you get all fishes out of the display and into q/t, thus
allowing the tank that fallow time we talked about, you should be golden.
I've been keeping the temp at 82 because all the info I could find was that it
need to be high to help with the protozoan problem, I couldn't find anything
that said "bring it down to normal after "x" amount of days. So I
will bring it down before I move the fish back from the QT.
>>You're on the right track, keep the temperature up to speed up the
protozoan life cycle (which allows you to shorten fallow time), but not so high
as to stress your inverts. Then, when you bring the fish back into
the system, 80F isn't terribly warm, but my own preference is to keep it below
80F, as I'd mentioned earlier.
I've tested the well water for nitrates and it is zero. That' why I was thinking
it might have some phosphates.
>>You wouldn't be doing an injustice by at least ruling phosphates out. You
can also get a pad of Phosguard into your canister, but my own method would be
to first determine whether or not they are indeed an issue.
My plan now is to purchase cured live rock from Marine Depot or Live Aquaria,
how about two shipments of 45 lb about a month apart?
>>It may be sold as cured, but I always (read: religiously) do my own
curing, just to be sure.
Think I can put in one batch into the main tank and then wait a month and add
another? I'll add more live sand with the first shipment of LR.
>>I really prefer curing/quarantining outside of the main
display--especially if you already have stock in there. Live sand
only needs be seeded, there is no "curing" time, per se. Otherwise,
be sure to cure all subsequent additions, and use that curing time to ensure
you're not introducing noxious pests into your carefully crafted system. You
will then be able to add specimens such as leather corals (Sarcophyton IIRC),
corallimorphs such as the myriad mushroom species, and maybe even some large
polyp stony corals. However, you did mention having an anemone in the
tank, and in my mind that would preclude the addition of most other sessile
invertebrates.
On the QT tank, should I start with a sp 1.020 (that matches the main tank) and
then with water changes bring it to 1.010? I've got a Vis-Jet skimmer
that was used on the 35g tank, would that be adequate? Do I need to include
another powerhead for circulation? How and how often should I plan
water changes on the QT? Thanks again, Cindy
>>I would start with the specific gravity at 1020 (though your inverts
will be happier if you bump it up to 1024-25), then bring it down over the next
day to 1010. I would not use copper while using hyposalinity. The
powerhead will be good on its own, you may want to add a sponge filter (yep, one
of those), but it's not at all a necessity. Typically, quarantine
systems for the hobbyist are set up and used only for new additions, they're not
left running and ready-cycled (as we see in public aquariums, for instance).
Therefore, I would make small, frequent water changes, even though you're not
using the copper (I'm making an assumption here on that). You should
be able to deal with ammonia and its oxidized brothers by making 10%-20% water
changes daily. I would also feed very lightly during this time, but
not so much that the fish end up losing weight. Also, be sure to
offer as many fresh or fresh-frozen foods during this time as you can (but not
brine shrimp), and if possible make use of quality vitamin supplements. Nutrition
is a very important part of the whole that keeps your specimens healthy.
>>Before I forget, be sure to watch your wrasse (I couldn't find a
definitive I.D. as "picture wrasse"--if you can photograph we can sort
it out) with the shrimps, snails, and, if you decide to add them, any hermit
crabs. Marina
Re: Do I need to start over again?
>Well, an update on my situation....I managed to move all the fish except the
wrasse. He/she seems to have disappeared and has not shown itself since Monday
morning. Should starting worrying after a couple of days?
>>I wouldn't, he knows you're out there! He'll get hungry soon
enough, and might decide to stay "under the covers" till the boogie
woman goes away. You absolutely will, however, have to get that
wrasse out.
>How deep do they dig themselves in? Is it a good idea to disturb the sand
bed to look for it?
>>Depth of dig is peculiar to each species, but I would expect him to not
be too far under the surface, an inch or two at most, though we could also
expect him to dig to the bottom. As for the sand bed, you don't
really want to dig the whole thing up. What I would do is move the
decorations (this will take some time) to one side, making at LEAST one third of
the tank free space. At that time I would place a piece of acrylic
inside the tank, not blocking the whole thing (but it has to be able to give a
snug fit, no escape routes at all), but blocking enough so that when the little
devil gets to the open area you can easily reach in and fully block his escape. You
will have to push the acrylic down into the sand, but this will only disturb a
relatively small portion, so you should still be golden. Then you
will be able to easily trap him on the open side, and drain out enough water to
allow you not to have to chase him so much. Be prepared for the fish
to flip out a bit, but it really can be done. He'll likely bury
himself, so if you have them have two nets, one to dig, one to place over top
for his escape. When he makes good his escape, bring that net up
FAST.
>I tested the main tank for phosphates and it was 0.4. Also tested the well
water (w/ the same kit) and it was undetectable, not sure that was good science.
I used a SeaTest kit that said it would work for freshwater. Made a
25% water change and 24 hr later the phosphate levels are the same.
>>Time to get a Phosguard pad...IIRC you're NOT using carbon, right? If
you are using activated carbon, get it out. It has been my own
experience that tests that "swing both ways" are fairly reliable. I'm
not too familiar with the SeaTest kits, so if you're in doubt you can ask your
local water municipality to test your well, as well. I don't think a
25% change will have much effect, you may need to make a full 50%-60% at once to
make a real dent. What needs to be sorted is the source of the
phosphorous--so I advise mixing a bit of your salt water, THEN test it before it
goes into the tank. Then, if the well water is clean, and you still
end up with phosphate readings, you'll have the culprit nailed. A
reading like this most certainly WILL cause you the blooms you're experiencing.
>As far as the algae problems, I may have been contributing by having the
lights turn on for a long time (about 16hrs).
>>Nowhere nearly as much of a problem as the high phosphate readings,
though it cannot be discounted, either.
>Is 12 -14 hr still too long? Also, since I live in Alaska, direct sunlight
is going to be a problem this summer. Where the tank is located it's gonna get
2-3 hr of direct sunlight. It's actually getting about half to 1 hr right now. And
being sun deprived all winter, I usually do not use blinds on the windows. How
bad is this going to be for the tank?
>>At such northern latitudes the intensity of the sunlight ought to be
significantly less than at equatorial climes. 12-14 hours of light is
perfect, as there is little shift in photoperiod within about 200-300 miles of
the equator. However, we're still leery of letting the tank get too
much sunlight, so I would either just tape some good, black construction paper
to the exposed areas, or devise something that can be set up and removed with
ease during this time. This way YOU don't have to be light-deprived,
but you will be able to better control what and how much light the display
receives.
>Thanks for the VERY helpful advise, Cindy
>>I am VERY glad I've been able to help you. If I ever get to
Alaska may I visit? <smile> Marina
Yikes! No room left for water!
Hey guys, great site, the!
I would like to know what you think would be the next step in upgrading my
aquarium! I know you'll probably say that a bigger one is better, but
I live
in a small apartment, so space is premium. This is what I've got:
16 g bowfront glass
36w PC 1/2n1/2 day/actinic
CPR BakPak
Minijet 606 powerhead x2
75 watt heater
16lbs LS
32lbs LR
LS and LR are amazing stuff from Tampa bay saltwater. Cheap and
awesome.
Initial cycling of tank took only two days, and Ammonia never went over 5ppm.
Livestock:
32 Astrea snails
16 Turbos
32 Blue Leg hermits
2 emerald crabs
2 peppermint shrimp
red brittle star
2 (1big, 1small) mantis shrimp (both uninvited, but not pests, yet)
The rock has many cup corals, star polyps, tunicates, clams, oysters,
scallops, encrusting sponges, macroalgae, small brittle stars, and those pest
anemones that I can't find in any of the books.
Also
1 true percula
2 3stripe damsels
1 bicolor blenny.
I also had a Florida Condy anemone that was getting really huge (4-5 "disk)
that disappeared.
I have added recently (2mos) a green Galaxea coral, octopus (or frogspawn),
green star polyps, Lobophyllia, colt, lobed leather, mushrooms, and a disc
coral.
I add Aragamilk 1x daily, 1drop per gallon, 1hour before lights out.
Feedings are live brine 1hr before lights on, flake at mid-day, frozen Marine
Cuisine 2hrs before lights out. Everyone is very happy, growing, and
multiplying.
Ammonia 0
Nitrites 0
Nitrates 0
Phosphates ~0 (unreadable)(thanks to sponge and store bought water)
pH 8.2
alk norm-high (according to red sea kit)
SG 1.022
temp 75
I'm sorry to have been so long winded, I want you to know that this is the
happiest and healthiest micro-mini-reef I have ever seen. It's only 4
months
old, I have never had slime algae problems, and the back wall, power cords,
and skimmer return are well encrusted with coralline algae. Basically
I want
to know what the next step would be so that I can increase the bioload (I
want to add a coral beauty and an LT anemone-clown), more LPS and soft
corals, as well as start some SPS and see how they do. More light?
what
kind? a refugium? with what, reverse light cycle? other
additives?
I apologize for the length of this email, but I am really proud of my tank,
and want to make it better. Thanks for your help!!
<Wow, your kidding right? The only recommendation I have is to return 1/2 to
2/3
of these animals to the LFS or someone who has the space for them. Don>

Help With a 55g Reef Tank 3/14/03
I've had a saltwater tank for approx. three years lately I`ve switched
over
to a Reef tank I know I don't have good enough lighting to have Corals so
im starting out with some mushrooms a flame scallop three anenomes a yellow
tang, two clown fish a Mandarin,<OH NO!! This is sounding really
bad!! Please tell me you have read some good books on reef tanks and
marine tanks in general.> two worm globes that are about a
foot long,<A foot, that's rather big...>
about ten turbo snails, six blue leg hermit crabs and now have about seventy
Lbs. of live rock my tank is a 55 with a Fluval 404 coupled up with
an Eheim
top water skimmer plus a Berlin protein skimmer my lighting is an 48' inch
Aqualight with two 65 watt 50/5os my anemones are doing a lot of
shrinking
the man in the fish shop told me that my anemones are very hardy. but at times
they look real healthy and other times they shrivel up.<Wow, you don't have
enough lights, what are you feeding?> Am I doing
something wrong<Please find a new fish store, and pick up a copy of Bob
Fenner's wonderful book "The Conscientious Marine Aquarist">
My Phosphate has ben off the scale but now it seems to be
dropping a bit. Please give me any suggestions you have.<I need more info on
your tank's water quality levels... You need more lights, anemones are just like
corals. They need lots of light.. in the hundreds of
watts. Please get back w/ me! Phil>
Going From a 7g to a 55g! 3/10/03
I like the new Link set up first off.<Thanks, it’s going to help people
find the info they need faster! BTW, Phil here on morning
patrol.> I always try and find what I am
looking for through the search, and usually (about 85% of the time) I find
an answer. I have seen similar ideas here, but not specific to my situation,
and nothing close enough so here goes. Not sure if you remember, but I
(unknowingly at the time) set up a 7 gallon Bow front tank as a reef about 4
months ago.<I think I remember reading about that.> I have been VERY lucky
about loss of livestock, and I do realize
that I need to upgrade soon.<Very good!> Presently I have yet to have a
problem with
water Quality other than High Calcium (about 485 ppm), I have a 3 1/2" DSB,
Lighting is a 36W PC SmartLite. Filtration is an Emperor 280, (400GPH) now
don’t go ballistic on the livestock; I know I made some mistakes, but again
all have been in the tank for at least 3 months and I have yet to lose
anything. 1 Mandarin, 2 small false Percula's, 1 Blood shrimp, 1 Peppermint
shrimp, assorted snails and Hermits, maybe 5 of each and one LT anemone
approximately 15lbs of LR, all covered in Coralline, reds, green, pink,
purple. I also have 1 zoanthid, 1 xenia, 1 blue Mush, all small frags. I
have begun to set up a 10 gallon Fuge, for nutrient support, it’s been
running for about 3 weeks, without plants (I live in California and its hard
to get these here) What can I do or where can I go to get plants other than
Caulerpa, LFS within 50 mile radius don’t carry, there are no reef clubs in
town and LFS will not order for me.<Try mail-order… www.inlandreef.com...
www.liveaquaria.com etc..> Is it possible to get enough Nutrients
without a lot of Plants?<Sure, but the more plants/microalgae you have the
more nutrient control you will have!> and what about mangroves, I
don’t want to be adding a
bunch of additives like it says to with them.<I’ve never used mangroves,
try using the google search or our chat forum… www.wetwebfotos.com/talk > I
will be "attaching" the Fuge
soon, like within a week.<Good good good> I know this probably
will not be enough nutrient
support for the mandarin, but what about the others?<It will help, just don’t
overfeed and keep up on those water changes!> I do plan in the next
month or so to buy a 55 gallon tank and will more than likely move the
mandarin, anemone, and fish to it once set up.<Possible problem
here! Mandarins and anemones don’t mix! It has been
recorded that some Mandarins wonder too close to the anemone and are
eaten. Just a word of advice.> I know I have made some
mistakes, all were made before I found you guys, but I am trying my best to
keep things going,<That’s good! I admire your strive to make
things better!!! You made mistakes as have I, and I probably will
make more. It’s life and the best thing we can do is live, learn,
and pass it on!> and think so far I have done ok. one last question, is
there harm in lighting an aquarium longer than 12 hours per day? Like maybe
14-5 if the extra hours are low level fluorescent only.. like basic?<It
should be fine, just make sure the bulbs are new/newer, it’s proven that old
fluorescents emit a wavelength of light that “feeds” algae. Note: Thanks
Ananda for filling me in on that one!> my tank
is in an area that is usually inhabited by people 14-15 hours a day.. not a
big deal... I would turn the low light on for about 1 1/2 hours before the
others and same for after I turn off the others,<No need to do
this. One this is that your running 36w, getting you 5.17 watts per
gallon. FYI, you’re going to want to get around this amount in the
55. So around 275-300w. Maybe a 250 metal halide and some
actinics.> sorry this got long..<IMO< it’s better that you get all
your questions answered and setup the tank right than have you not know what to
do and setup wrong.> and
thank you again.<Aaron it sounds like you have a plan! Good luck
and please send some pictures along when it’s all setup! Phil>
A "Total" Eclipse!
First, congrats for a great site (I just found it on a Google search), great
service, and great bedside manner ;->
<Yeah- but I make lousy coffee! Scott F. with you today!>
I'll ask about my "large" SW tank today, then hit you up for the other
tanks another day :-)
<Go for it, braddah!>
Tank 1, 37g "All-glass", salt, fish & inverts, 2-3 yrs old.
Tank & equip:- 37g 30 x 12 x 22high Marineland Eclipse 3 hood with standard
foam/carbon filter and bio-wheel; 1 x 24" Power-Glo, 1 x 24"
Marine-Glo (actinic), 11 - 12 hrs/day, typ; 200W immersed heater; 35lbs LR
approx (as much as I can safely stack while not hitting the sides), plenty of
hard purple and deep red algae;
black "sand", about 1 3/4", (not sure I like this stuff);
1 x Magnum 350 Convertible canister filter, run whenever I can tolerate the incessant
chirping!; 1 x TetraTec UV5 UV clarifier on output of Mag 350; population:
1 x Koran Angel; 1 x Yellow Tang; 1 x Coral Banded Shrimp; 1 x 5 1/2"
"gosh-knows" long tentacle anemone - white with pink & purple
coloration; 1x tomato clown - bonded with the anemone; 1 x feisty
"humbug" (black & white) damsel; 1 x huge brittle star (12"
dia). Stats: T=77F, SG=1.023, pH=8.3, KH="hard", per Tetra test;
NO2=0;NO3= 50-100 mg/l. (OK, so I should change water more often ...)
<Yep- and consider a deeper bed of fine sand for a more complete
denitrification capability...you'll see a positive impact on nitrate levels...
Also- the Koran and the tang are a bit too much for this tank...you'll need to
upgrade substantially fairly soon in order to maintain these guys in a healthy
condition for anything close to their natural life span!>
Water: street water is hard, but chemically fairly clean here in MN; I take it
after my domestic water softener, then through an Omnifilter OT32 2-stage
filter. Evap replacement done mostly with that water, occasionally with
kalkwasser.
I run the Magnum 350 with foam sleeve & carbon when I clean the tank, then
with the paper filter for a while after that, but not continuously. Q1: Is it
helpful to have the bio wheel running or should I leave bio-filt to the LR ?
Presumably I still need the Eclipse's mechanical filter.
<I like the Biowheel, but personally- I'd let the live rock do most of the
work!>
Q2: Is the magnum 350 helping me here? I rarely run it - usually only
during/after tank cleaning, etc.
<Mechanical filtration, such as that provided by the Magnum- is very useful,
provided that the filter media are rotated out and/or cleaned on a very regular
basis. Mechanical filtration can become notorious "nutrient traps",
which can lead to nuisance algae outbreaks- if attention is not paid to
maintenance>
Q3: I haven't installed a protein filter - tough under the Eclipse hood. Should
I?
<Yes! If you can figure out a way to retrofit one- I absolutely would. A
skimmer is the single most important piece of equipment you can obtain for a
marine system! I have seen posts on various discussion boards, such as Reef
Central, about adapting a skimmer to an Eclipse system>
Q4: After adding and running the UV5 my Eclipse filter never clogs,
even though I run it rarely. Does this mean the LR is happy? Perhaps I outgrew
my over-feeding phase?
<Well, I'm not sure if the UV has anything to do with a well-functioning
mechanical filtration system...I'd chalk up your success in avoiding clogging
with good husbandry habits and attention to the basics...And not
overfeeding!>
Q5: what else should I be testing, and what kits would you advise to do so?
<I'd test for phosphate, and maybe calcium>
Q6: what do you think about corner units (54 or 92 are available) for SW?
They're cute, but lighting is tough. Anything else? Or should I go with a
standard 75 rectangular if I can get spousal approval?
<Well- there are lots of cool lighting options for these kinds of tanks
now... HQI halide pendants, PC retrofits, and others. I'd go for the largest
tank that you could get spousal approval on! You need a 100+ for that Koran,
bro!>
Q7: open ended question - anything you'd change or advise? Many Thanks! Julian
<Well, Julian- sounds like the system is basically working well. I'd work on
getting those nitrate levels down...Going with a 3-4 inch layer of live sand
would really help. I'd figure out a way to get some chemical filtration media
(activated carbon and/or Poly Filter) in the system on a regular basis...These
can have a great impact on organic (read: "nitrate" again!) levels in
the tank. Also, be consistent with those water changes...Small (5% of tank
volume), twice weekly water changes will have an amazing beneficial effect on
your tank- I guarantee it! Give it a try- we're talking about 2 gallons twice a
week in this tank...Easy! Finally, you'll need that larger tank to keep the tang
happy- they really need a lot of room to live long, healthy lives...Keep
reading. learning, experimenting, and sharing- you're doing great! Good luck!
Regards, Scott F>

Expanding A New Setup
I just set up 180 reef 5"dsb about a 35 gallon sump has bio balls in it
now going to remove in 3 or 4 weeks.
<A good idea, IMO...No sense having a "nitrate factory" and a
superior nitrate export mechanism together...seems counterproductive.>
150lbs lr. My question is, I can not really do a DSB in the sump- no baffles.
Plus, my Euro Reef TS8 skimmer is pretty large. Also have a calcium reactor on
the way, and well-I'm out of room in the cabinet. My wife did not seem to like
the idea of cutting a hole in the wall and converting her closet to a refuge etc
<I cannot imagine why! LOL>
...so can I just do lr in the sump, no DSB, some lights and macro algae?
<Well, sure- lots of people do this...However, you won't get the same
benefits that you would from a DSB...I'd just go for the DSB in the display
tank>
Or am I better off just leaving the sump empty.. poly filter maybe carbon every
so often?
<That works fine, too- regardless of whether or not you're using rock, sand,
etc. in the sump. You could light the sump and grow/harvest some macroalgae,
such as Chaetomorpha or Gracilaria (my personal favorites!)...This is an easy
way to enjoy another means of nutrient export...>
..also now that the lr is in the tank (cured it in tubs for a couple of weeks),
what critters would you add 1st? Types of snails hermits stars cucumbers? and
how many?
<I'd add some Trochus, Strombus, Nerita and Astrea snails, maybe a brittle
star or two. Most of the etailers that sell these creatures have them sized in
"packages", with appropriate numbers of these animals to suit various
tank sizes...>
Last question: My MH lights get really hot. I have a fan, but still gets too
hot? Maybe a dumb question, but should I just add another fan, or is there a
better one out there? Have a 3" fan now....
<I am a big fan (no pun intended!) of the Ice Cap variable speed fans- they
move a lot of air, and are available in 4" and 3" sizes...They are not
cheap- but they are high-quality units, IMO. Other hobbyists will use less
expensive clip-on fans (like the kinds designed for desktops, etc.). Most of
them work pretty well...You may have to do some experimenting to see how many
fans, and in what configuration- are needed to do the job in your system...Have
some fun with this--It can be really interesting experimenting>
Thanks for all your help...Scott Mutter
<My pleasure, Scott! Regards, Scott F.>
Working His Plan!
Hopefully I'm on the right track, but I have just a
few questions before I go and purchase any of this
equipment. I'm planning on a FOWLR with an invert
cleanup crew. Eventually planning on corals and other
types of inverts.
<Sounds like a nice plan!>
What I have planned so far:
75 gal glass w/ 2 returns top rear corners and 1
overflow box
20 gal sump
2 Ebo-Jager 250wt heaters in sump
Aqua C EV-180 Protein Skimmer w/ Mag 7 pump
Mag 18 return pump w/ ~6' head at 1125 gph (15x water
turnover)
~96 lbs of Fiji, Tonga, and Caribbean uncured live
rock to preserve diversity (will use to cure tank)
~100 lbs live sand ~2" bed
~6 watts per gal lighting (175wt 10K MH, 110wt
Actinic White VHO, 110wt Actinic 100% blue VHO, 40wt
NO Actinic White
misc - testing kits, DI unit, thermometer, etc.
Ok now for the questions... Have I left out any major
components?
<I think that you did fine...I'd increase the sand bed to at least three-
four inches...better for denitrification and nutrient export processes...two
inches is too shallow, IMO>
How large should the overflow be 1 1/2" - >2" w/ 15x water
turnover?
<I'd use two 1.5 inch standpipes...2 inch standpipes would be better,
though>
Is that lighting too much?
<Depends on what you intend to keep...Should be fine for most corals that
require moderate to bright lighting...still might not be enough(!) for some
really demanding species...>
Any assistance will be greatly appreciated.
Thanks, Jeremy
<I think that you're on the right path, Jeremy...Just study carefully the
species that you intend to keep. You're off to a good start! Regards, Scott
F>
Sand beds, lighting, livestock for 29G
Hello,
I have a 29gal. aquarium with 45lbs or so of live rock. I was wondering if a
deep sand bed can cause problems? I've heard that they cause problems after a
while. Right now my sand bed is almost 3in. I was planning on making it deeper
but I’m not sure if I should. Would it be better to lower it to less than an
in.? if it is gonna cause problems then I don’t want
it I’ve heard bad / good about it so I’m not sure.
<IMO the 4”+ sandbed has many more benefits than negatives. I would go
another 1” or more>
The link on deep sand beds on wetwebmedia.com doesn’t work there’s no words.
<Yes my friend it does work. Click on the blue links at the top of the page
to read info about substrates/DSBs>
What corals can I keep under a 1x55watt and a 36watt pc? I know mushrooms and
polyps but what else? (maybe a colt coral or finger leather or something??)
<Mushrooms and polyps are something, aren’t they? I would stick to
these>
...and how often do the pc's need to be changed?
<9-12 months>
I have about 15 turbo snails they do a god job on algae but only on the glass
and rocks...not the sand that has most of the algae, so what should I get to
clean that up?
<See here and the links at the top of the page for more http://www.wetwebmedia.com/marscavfaqs.htm>
Here’s what I plan for fish..... 1percula clown fish 1 royal gramma 1 Firefish
goby 2 Banggai cardinals and another small fish maybe a sixline wrasse? any
problems there?
<I would stop at 1 percula, 1 gramma, 1 Firefish, and MAYBE one Banggai. More
than that is too much for this small volume of water.>
thank you very much,
<Your welcome, Don>
Fish Stories...
Hi Bob,
<Scott F. in today>
I hope you're doing well. I have a few questions...
1. I'm going to be showing a tank in a fish show in May and I don't
feel like dismantling all the rock in my tank. What is the best way
to get real or fake coralline algae on dead rock? Dye? Soak
in coralline algae soup?
<Well, in addition to providing proper conditions for its development
(calcium, magnesium levels, etc), I'd consider some coralline algae
"starts" that companies like Indo Pacific Sea Farms and others offer,
which will help "seed" you system with initial growth...>
2. I have a lovely canary blenny that is hard to feed. I've
given him spirulina, frozen food, pellets, plankton, baby brine shrimp... nada. He
only has a taste for whatever occurs naturally in my tank and live adult brine
shrimp. I don't mind buying brine shrimp, but is there anything else
with which I may supplement his diet?
<I feed mine frozen mysis...They really seem to like them, once they acquire
a taste...Also, you could enrich your live brine shrimp with a preparation such
as Selcon, to add a bit more nutritional value. I'd keep trying various frozen
foods until the fish finds something that interests him...hang in there!>
3. Do flower anemones need much food other than lighting? I
have a pretty purple-mouthed/green tipped one that loves its spot under the
metal halide.
<Well, "flower anemones" unfortunately can describe many possible
species, some that may be entirely autotrophic/photosynthetic, or others that
need regular feedings...Best bet- when in doubt- try feeding and note the
results...>
I hand feed it about once a week and do Dt's every other day. Anything
else I should do?
<Sounds good to me...>
Also, I know that anemones are long lived, do you know what the lifespan for
flower anemones is?
<Well, for most of the cnidarians, the lifespans can be very, very
long...some scientists postulate potential life spans of hundreds of years for
anemones!!! Much research still remains to be done on them to answer this
question...>
4. What makes black caps (fish) delicate? What are their dietary needs?
<They are generally found in deeper water, and require careful acclimation
and collection procedures in order for the fish to thrive in captivity. Handling
is very important with these guys...Often times, a fish like the Blackcap
Basslet has its fate decided before it ever reaches the LFS...Observe the fish
carefully before purchase, acclimate them carefully and slowly, and don't
neglect quarantine. They are basically plankton eaters, so a diet rich in mysis
and other frozen plankton should work well>
The reason I ask is I want to put one more fish in my 58, but I'm afraid that a
chevron tang or a rusty angel won't have enough room in my current setup.
<I agree- you really need a much larger tank for the tang, and somewhat
larger quarters for the Rusty...Maybe a C. argi would be a better choice if you
want an angelfish>
Right now I have my bi-color blenny, canary blenny, and Japanese wrasse. Can
you recommend a suitable addition that won't need to compete with the others for
food?
<I like blennies, gobies, and Basslets. Maybe a Royal Gramma? Perhaps a
peaceful, calm fish, like a Cardinal fish...lots of possibilities here...Just go
small!>
5.Do you know of any good way to treat algae that invades dead spots on a
Lobophyllia?
<Just careful physical removal, IMO>
For future reference if you need it: You may treat dead spots on open
brains by brushing away the algae (w/ toothbrush) and applying waterproof glue.
Here its called Future glue, we use it to glue coral frags also. I did this with
one of my open brains and it healed over completely. The Lobophyllia is
different so it didn't work.
<Interesting information- thanks for sharing! BTW- Anthony wrote a piece not
too long ago about brain corals "coming back" after what appeared to
be a loss of tissue...It pays not to give up too quickly...recovery is possible
under the right conditions!>
Yes, its the smoking jacket and kimono question again.... Can you sex
any of these fish: canary blenny, Japanese wrasse, chevron tang, and
rusty angel.
<Maybe the angelfish might exhibit some external differences: brighter
colors, more pointed fins in the males...but this is not 100%...I'm afraid that
the best way to tell the boys from the girls is by using a dissection
kit...yuck!>
I'm not talking about an orgy either. ;]
<Perhaps just an intimate interlude, huh?>
Do you think anemones are emotional? ;]
<I'll ask mine!>
Thanks for everything and have a great weekend!
Morgan
ps: If you or anyone you know will be in Miami during May please come
check out the Florida Marine Aquarists Society show being held at the Ft
Lauderdale IGFA fishing hall of fame. It should be a very good show
this year. Take care!
<Wow! Sounds like a good time! Anyone....? Take Care! Scott F>
Re: REEF HELP
Hello Mr. Fenner,
<Craig here tonight>
I hope you will reply, I need help.
<We always reply!>
I have a 30 gallon reef with a magnum 350 pro, a BakPak 2r skimmer, 1 powersweep
zoomed 228, JBJ lightning, no sump or plenum, and an 1" crushed coral
gravel. Parameters are; ammonia= 0, nitrite=0, nitrate=10ppm, phosphate is high.
I have a couple of mushrooms , 1 button polyp, 3 peppermint shrimp, 1 maroon
clownfish, and lots of snails[ Ceriths, Astrea, Nassarius]. All my other corals
died summer 2002-too hot, no chiller. In about 2 weeks I'll be getting some
corals and fish from a friend, and I want to get the system running well before
that. I'm also getting a little extra algae, I guess due to the
nitrate and phosphate. I recently put a denitrator-carbon-PhosGuard mix to
canister to lower the numbers.
<Check source water, increase water changes, change filter media in canister
before it produces nitrates. Re-evaluate feeding in addition to testing source
water for phosphates.>
I don't think there is any denitrification going on in the gravel cause it looks
dirty below with algae and red brownish stuff.
<No, exactly the opposite, it is going wild with all the waste trapped in the
crushed coral producing nitrates. Trapping food and phosphates as
well. This isn't the best substrate.>
I know its probably because of the 1 inch that's not enough.
<And too coarse, allowing food/wastes to be trapped. Needs regular
maintenance.>
My friend also offered me some live sand, can I add the sand
on top of the gravel or should I remove all gravel altogether.
<Remove the crushed coral all-together.>
I would like to just add about 2 inches of live sand on top of the gravel, but
don't know if this is beneficial for the tank.
<Nope, you entrap the problem wastes.>
Please help, eventually I would like to get rid of canister filter. Any advice.
Thanks, Andre
<No need to get rid of it, it is useful for carbon and chemical filtration
like you are using now. Best of luck! Craig>
Foam on The Macro
I have yet another question for the experts! I have a refugium with various
macro algae's mostly grape and feather Caulerpa , I harvest weekly and the
lights are on 24/7.
<Good nutrient export if you harvest weekly!>
I have noticed that on the water surface in the refugium a white foam that
collects around the algae, the surface is agitated by the water flow from the
main tank. Any idea on what this is and what needs to be done if
anything. As always your opinions are appreciated. Mike Winston
<Hey, Mike- I know exactly what you're talking about here...I've seen it too.
Sounds like some organic foam, possibly analogous to "skimmate" from
protein skimmer effluent (but not as concentrated). I'd remove it by using a
net, or a piece of paper towel placed on the surface of the water in the
refugium, then quickly removed. Hope this helps! regards, Scott F.>
Re: Reef Tank
Hi. I have a 75 gallon tank with 75 lbs of live rock and 75 lbs of
aragonite. I am using a wet/dry with built in venturi skimmer and overflow
made by Aqua Clear Aquatics in Jacksonville, FL. I have a few questions.
1) I currently have a 260 watt Power Compact (4 65 watt bulbs), 2 10,000K
Daylights and 2 Actinic Blue. I want to stock some soft corals, mushroom
corals, colony polyps, and perhaps a sebae anemone and some clams. I was
wondering if my lights are sufficient for these species.
<I would skip the anemone, at least for now. Your lighting should be fine for
a mix of the rest listed. Please see here re anemones: http://www.wetwebmedia.com/marine/inverts/cnidaria/anthozoa/anemones.htm
and the related FAQs (linked, in blue, above)>
2) Should I remove the bio media from the sump? I have read about wet/dry's
being nitrate factories.
<I would... please see here: http://www.wetwebmedia.com/bioballfaqs.htm>
3) I have purchased a Sander's model ozonizer (25 mg/h) in hopes to make my
skimmer more efficient and better water quality and good Redox potential. I
was advised by my LFS to get a small air pump to pump air through the
ozonizer and then hook up the airline from the venturi to the ozonizer.
<I would try just using the venturi first. Likely the pump is unnecessary>
The
effluent will pass over activated carbon. With such a small unit, should I
get a ORP controller?
<I would wait here... instead measure Redox or pH change... see if the unit
is capable of too much ozone effect at maximum output... You likely don't need a
controller>
Is drying the air before the air enters the ozonizer
really necessary? If so, how can I accomplish this?
<Not necessary, but advisable in some cases (where the humidity is high, the
efficiency of the unit important). Simple drying mechanisms can be had, built...
Once again, I would try the unit "as is" first.>
Ammonia - 0
Nitrite - 0
Nitrates - 10 ppm
Alkalinity - 3.5 milliequivalents
PH - 8.4
Temp - 82
Not sure on Calcium, as I don't have a test kit yet, but I have been daily
dosing Kent Marine Calcium along with Kent Marine Super dKH buffer once
every two weeks, Kent Marine Iodine once a week, and Kent Marine Strontium
and Molybdenum every four days.
<It is strongly advised that you not dose/add anything you don't test for...

Will ozone be more beneficial, or more trouble than it's worth?
<Very likely beneficial>

"U" Tube air bubble, mandarin, pods, etc
Hi guys,
My tank is a 55g w/20g sump and I have had it set up in my apartment since July.
Things have been going pretty well. My Naso, "Pootie", is really cool
and he loves attention and seaweed selects. Corals have been doing pretty well-
I have an Alveopora that has been growing steadily (but slowly) that I am
particularly proud of. 130w smart lights and 64w of actinic and 10k fluorescent.
I was wondering if this is enough light for a squamosa? Also, I bought a pair of
mandarins in November, but they didn't get along and the male didn't make it.
The female though seems to be doing well and has apparently changed sexes. I was
wondering if this was perhaps a sign of good health? I have a growing crop of
copepods in my sump- will these go through the pump into the main tank, or how
else can I feed them? and finally- I built my overflow box myself, and it
worked well for about a month until the air bubble at the top of the
"U" tube got too big. Any advice on how to prevent this? Thanks so
much, Hunter Leber
<Hi Hunter, You may be able to keep a squamosa close to the surface/light. As
you are aware, clams need high intensity lighting. A good sign of health in
Mandarins is being fat and well fed, sometimes hard with this fish without
enough well established live rock and pod populations. Syringe them with a
baster from the sump and squirt them into the main. To fix your "U"
tube forever, drill a hole in the very top where the bubble forms, glue a piece
of rigid air tube and attach it to a powerhead with a venturi feature. This will
pull the air out while running and in power outages when the powerhead comes
back on. Have fun! Craig>
Refugiums, skimming, additives, etc.
I have a well established 110 gallon reef tank that is heavily stocked with
fish, corals (sps, lps, and soft corals), corallimorpharians, zoanthids, and a
few shrimp. The system runs an Excalibur in-sump skimmer which, now
that it is broken in, works very well. This morning I
plumbed in an EcoSytem
2140 refugium (the smallest one, maybe 10 gallons of water). I
realize that this size refugium is small for a 110 gallon tank, but I added it
to help with nutrient export and to act as a nursery for copepods and other
small beneficial life forms. My questions are:
<This size refugium is really too small to do what you think it may....fun to
play with and it will produce pods, use some nutrient, etc. but you won't be
shutting down the skimmer, losing your carbon or not dosing needed supplements
(when determined by testing). A refugium needs to be at least one third the size
of the main to really perform as advertised.>
1. The bio balls that came with refugium are so less than
efficient at breaking up the air bubbles that it is laughable. Any
suggestions for stopping the air bubbles?
<I would consult Ecosystem. See the link at the marine pages of WWM.>
2. Is the Miracle Mud the way to go or should I use some other
substrate such as fine sand or Aragonite?
<I like a mixed grain substrate and it is less than the price of gold and
miracle mud. The price of miracle mud is the miracle!>
3. I do not want to discontinue using my skimmer. Is
there a
problem if I continue operating it in conjunction with the refugium?
<Nope. I suggest 24/7/365!>
4. I use 1 cup of carbon, changed every 4 weeks in my sump. Should
this practice be discontinued?
<Is this passive or in a powerfilter? If it is passive it probably doesn't do
much and should be more than a cup! I would continue to use carbon.>
5. The only additives I use are ESV Iodine and Strontium, once
per week, and make up water is kalkwasser. Should I continue the
Iodine and strontium?
<Yep, per test/use.>
The irony, of course, is that I actually believed I completely thought out what
was involved with adding this refugium before I purchased it and again before I
plumbed it. Anyway, any help you can offer is much appreciated. Thank
you for your anticipated response. Michael Jacobs
<Join the club dude, we all have done something like this. Enjoy it for what
it is and learn from it. It will contribute, certainly with pods, etc absent
predation, but it won't be a huge impact like a refugium of 30-50 gallons. Best
Wishes, Craig>
2/6/03 - A few issues
Hello everyone, <Sorry for the delay. Not sure how this one was passed
up. Paulo, wiping the sleep out of his eyes.>
I could use some advice. My reef is an 18 month old sumpless and
skimmerless 65g w/ a 20g upstream refugium. The main tank has 80# live rock.
6" DSB, 400w m/h 10k Ushio. The livestock consists of 4 green Chromis, 2
false percs, 1 lawnmower blenny. 12 assorted Montipora and Acropora frags all
below 4" tall, 1 Sinularia, 1 small patch (3" round) of xenia and
anthelia all separate from the sps frags and 1 green BTA.
The refugium has a 4" DSB,
65w pc lights, 1 small piece of live rock. The refugium "was" full of
Caulerpa Prolifera but has all been removed and replaced with Gracilaria and Ulva. The
water parameters check out okay, temp 82.f , calc 400 - 425, alk 3.5, sg 1.024,
ph 8.2 . I add Kalk through a peristaltic pump set on a float switch. <Sounds
like a nice setup overall. Should use a skimmer though>
Until 2 weeks ago everything was
in good shape. I had been
running the tank skimmerless for the past 6 months. After hearing about the
potential problems with Caulerpa at the last Boston Reefers meeting I had
decided to pull all my Caulerpa. <Understood> This is where things seem to
have gone wrong. I had pulled 95% of the Caulerpa at one time and replaced it
with the new macro algae. <Good intention but maybe should have been less
drastic and slowly removed some algae and replaced with the macro. Step by step
process> I removed as much of the leftover debris from the Caulerpa forest as
possible which still left a quite a bit of detritus in the refugium. <The
reef hobby in general is becoming more aware of the release of growth inhibitive
as well as the release of some of the nutrients that they are purported to
ingest when Caulerpa are disturbed by breaking or grazing etc.> Since then I
have been fighting mats of the black/brown/maroon cyano blooms on the sandbed in
both tank and on the glass in the refugium. <Maybe related to the above
theory?> The polyps on some of my sps have not returned to there former
glory. A hairy Acro frag has not extended its hairy polyps since and the blue
tips are not as bright as before. It seems none of the colors are as bright as
before. The pod population does not seem to have shrunk but the amount of
bristle worms seems to have gone down quite a bit. <Keep the water changes
coming. I believe you stated you now have the skimmer running. Very good
idea!>
To remedy the problems I am
experiencing I have done 3 x 10g water changes and put my hob skimmer back in
service. <More water changes would not hurt.> I remove the cyano when
possible and the debris in the refugium. The refugium debris smells pretty bad.
Instead of me asking a bunch of questions could you explain where I went wrong
and the best way to remedy the situation.<Well, there are many possibilities
here. Water changes with skimming will definitely help. Time will tell. Continue
scrubbing and siphoning off with your water change regime. Running some carbon
somehow would not be a bad idea either. There are many links available here on
wetwebmedia try this: http://www.wetwebmedia.com/refugium.htm.
See if there is not something that I may not have covered.> I hope I
explained everything well enough but if you should have any questions please
ask. Thanks in advance. <Good Luck. Pablo out>

LFS advice in doubt for Reefing
Hi there, I just spent the last hour perusing your site and found a great
new source of info. Thank you.
<our great pleasure, my friend>
Now, my turn to pick your brains.
<ahhh yes... with Fava beans>
First the facts: 55 gallon, 6 month old tank. I have a PM
skimmer and a Fluval 404. All my chemicals have been steady for the
last 3 months except phosphates which are off the wall.
<hmm... do examine your foods and feeding (the likely cause). A common
mistake is to thaw frozen food and forget to strain the meat away. Pack juice
poured in to the aquarium is a horrifying source of nutrients>
I've had LR for about 2 months and used RO/DI for about 2 months. I
have 2 Clarkiis, 1 anemone, 1 fire shrimp and 4 snails. About 3 days
ago, I bought 1 Yellow Tang, 2 Firefish and 1 purple Firefish and a green hairy
mushroom. I know that is a lot, but my LFS suggested that the
numerous new inhabitants would prevent the Clarkiis from being to
aggressive.
<the bio-load is not the problem so much as they were all added too fast. The
rationale by the LFS was complete bunk if not dangerous advice>
True enough they are all fine.
<not true, bud... just coincidental and lucky>
BTW, the back of my tank is about 70% covered with hairy algae but very little
is one LRs or anywhere else.
<indeed not a surprise with your high nutrient levels. I am quite certain
that your skimmer is not giving you a full cup daily like a tuned and tweaked
model should. In fact, with that much hair algae an high phosphates I'll guess
that you barely get a coffee colored cup even once weekly. And if my psychic
abilities <G> are really attuned, I'll venture to say that the LFS clerk
that gave you that previous advice on husbandry also sold you a difficult
skimmer (Prism, Red Sea, Seaclone?)>
Enough with the history, now the questions:
Will the Tang eat the algae?
<heck ya... but not rasped clean... just cropped>
I tried broccoli, didn't jive. I'll try lettuce tomorrow,
<Ack! no land plants please! No spinach... no broccoli... no lettuce. They
are grown with concentrated fertilizers (nitrate and phosphate) that pollute
your tank with concentrations of ppt (thousands!) not ppm (millions)>
but I want to know if I can put Caulerpa straight in the tank to grow?
<wow... please do not use the Caulerpa my friend until you have spent some
time in the WWM archives reading on this topic. You may very well be going from
the frying pan into the fire>
If I feed the phytoplankton to the mushrooms on a weekly basis, will it be
enough for the Firefish?
<neither creature mentioned eats phyto. In fact... if you don't have a bunch
of sea fans or Neptheids in your tank, I'm wondering what the bottled phyto is
going to do besides grow more algae. More bad advice dude. Most all corals and
your Firefish are dedicated zooplankton feeders. Try Frozen mysis, Pacifica
plankton, jar Sweetwater plankton, etc>
What else, do I feed them? I currently am feeding the Clarkiis
pellets and adding frozen brine shrimp every 3rd day and half a frozen fish for
the anemone once a week. Is this alright?
<the pellets are very fine but the brine shrimp is a hollow food (see
nutritional analysis on package... moisture content). Fish can literally starve
to death on brine shrimp. Most any other frozen food is better (see list
above)>
My LFS is knowledgeable but it seems that you guys are better. Sure
could use some advice.
<I am very skeptical about most all of the advice you have been given so far.
We truly want you to succeed. Please do spend some more time reading in the
archives too about topics that interest you. Do review nutrient control, algae,
protein skimmer FAQs, etc>
Thanks a lot. Bobbie
<best regards, Anthony>
RE: Course of action on a neglected tank?
Hello again!...
<"Hello...just called... to say... Hello" Neil Diamond fan? Hmmm...
never mind>
I have recently started implementing your advise on getting my tank back from
limbo. I agree totally with you on the lack of performance on the skimmer. As
a result, I replaced the original venturi cone on the Berlin Classic with a Kent
3/4" venturi ($25, LFS) powered by the original Mag 7. What an amazing
difference in bubble production!!
<excellent to hear!>
Even after cleaning the skimmer with a bleach solution and rinsing, it started
producing dry foam immediately. I am convinced that there is no such
thing as a break-in period... The skimmer is either a good design or not.
<HOW TRUE THIS IS!!!! "Break-in periods are excuses made by
manufacturers of poor skimmers for the most part <G>. We have seen
skimmers pull out cups of excessive bio-mineral (chalky milk) from raw new
seawater that had no life in it! Its either a good skimmer or its a
wheel-chuck>
Hopefully this improvement will start reversing the growth of BGA and hair
algae.
<agreed>
My next attack point is in increasing the water flow. I plan on
redesigning the PVC plumbing to include two surface return spouts, getting rid
of the spray bar behind the rocks, and reducing head loss by minimizing pipe
bends.
<agreed>
I have a Dolphin Tankmaster 800 as a dedicated return pump and hope this will be
strong enough for decent flow.
<agreed likely>
In a few weeks I will be purchasing a 4-stage RO/DI filter and using it for
water changes and evaporation replacement as well as mail-ordering a cleanup
crew of some snails. I have also started (again) to use Kalkwasser for a Calcium
source.
<yes! Many benefits here outlined in the WWM archives>
Is the Kent Marine - Liquid Calcium product I have been using OK?
<nope.. thanks for asking. Its Calcium chloride.>
You mention some additives containing chlorides that interfere with the calcium
levels over time.
<calcium chloride products like Kent Marine's Liquid Calcium are excellent
for temporary fixes of Ca deficiency. They lack numerous benefits that the
hydroxyl Ca has and they impart Chloride ions which accumulate in time and ca
skew chemistry>
I need to focus on a balanced calcium/buffer regimen.
I do need your opinion on one other matter. The main tank is a 50gal
with 3" sand and 50lbs LR and a 10gal sump/refugium, divided 30/70
respectively. The refugium area has 2" of sand where I have been trying to
grow some Caulerpas, when they aren't covered by hair or BGA.
<I would say that here the weak sand depths (under 3") is hindering do
and your algae problem as it is likely a nutrient sink unless you stir it often.
It would be better deeper (4") and may not even need stirred then>
Lighting is 24/7 by a NO 50/50 bulb.
<weak light indeed... especially if the lamp is over 6 months old (useless
over 10 months by some estimates)>
The actual water volume is about 5gal and I keep a bag of
carbon in the pump section. Do you think the sand has any effect in
it or should I remove it?
<a benefit over 4", a liability between 1-3" and no harm under
1" IMO>
I can't fit a bigger sump under the cabinet so I am forced to use this size, but
I want to make it as efficient as possible.
What would be the best way to utilize a sump/refugium of this size?
<that depends on what you want the refugium to do. Deep sand for NNR. Dense
Chaetomorpha or Gracilaria for nutrient export and plankters instead. Any will
do all to some extent but focus on a primary goal and address it, bud>
After a period of accepting mediocre tank conditions, your advice has sparked up
my determination to have a great system again.
<awesome to hear!>
Your help is greatly appreciated. Regards, Glenn Koenig
<thanks kindly, Anthony>
Reef and Fish troubles
Awesome site!!! I find many many answers here. It, for me, is the most
knowledgeable site I have ever been to.
<thanks kindly... it warms the heart to hear fellow aquarists tell us that we
are really full of it. Just full of it. The biggest pile of it they have come
across on the net. <G>>
I find myself reading for hours and hours and learning more than I thought I
could ever know.
<you don't have a computer in the lavatory do you?>
Thank you!
<our pleasure my friend>
I have been in the saltwater hobby for 17 years.
<awesome!>
I have all levels in the correct parameters. One thing I want to ask is my
friend uses a Ocean clear canister filter that he cleans once every 10 months to
a year. Is this a good filter or by leaving it in the system for a year only
traps waste
product and keeps it in the system?
<they are old and worthy bastions in the industry. They (like any mechanical
filter) can be a serious problem for nitrate sensitive fishes and inverts... but
then again, even that can be skirted with DSB methodologies, light bio-load,
etc. Ultimately, I love these filters but generally don't recommend them. Simple
and better systems can be had with merely live rock and sand... water changes
and skimmers. Large fishless refugiums too>
He also uses a Eheim canister filter and doesn't do many water changes,
<there's always these rare knucklehead friends of ours that are the
exceptions... cleans filters once yearly, rarely does water changes... I'd
really like to smack him>
but he is able to keep a Powder Blue Tang
<sure... its alive but being forced to live in its own (daily) accumulating
and dissolved feces. It doesn't make it right... just makes your friend lucky.
Water quality is assuredly miserable and DOC levels must be through the roof.
When the ASPCA starts to regulate cruelty to fishes... your friend is screwed
<G>. Do that fish a favor and cc this message to your bud please.>
(which seem to die in my system) his Nitrate levels are totally off the board,
200ppm,
<actually... his actual nitrates are 4.4 X 200 (if the test can even read
this high end accurately. Nitrate as an ion versus nitrate-nitrogen). His actual
nitrates are literally around 1000ppm or more. He could probably distill his
water and sell the concentrated nitrate to the government for military
applications>
and yet his Tang is living fine for over a year.
<living but not thriving and I guarantee it will not see a full lifespan if
it even sees another year>
Can you tell me why mine keep dieing and I am only at 40ppm.
<many reasons... lets assume that you are buying the exact same fish from the
exact same source... your buddy either has a longer tank (6'plus) and/or has
much better water flow than you. PB tangs are VERY strict about large long tanks
and massive water flow. These are the two most common obstacles. Many other
possibilities including one that his tang is actually a damsel in disguise>
It is not that I don't take care of my tank,
<understood>
I have a Flame Angle and a Flameback Angle that I have had
in this system for 4 years now. (yes, they are living together and not killing
each other)
<good to hear>
I use a EBB-N-FLOW filter (Algae filter) I am not really happy with this
technology and feel it is not working well.
<not harmful... just insignificant and weakly effective. A large refugium
would serve you much better... just no Caulerpa. Gracilaria or Chaetomorpha
algae instead.>
Could this be the reason many aquarists have totally abandoned the Algae filters
and gone to "MUDD" filters.
<ahhh...no. I don't think mud filters are that extraordinary either.
Helpful... but they do not save tanks, stop jock itch or grow hair. They are
simply a convenient means of nutrient export and that's a good thing>
Would I be better trying to convert my filter to a Mangrove filter
<mangroves are cool but grow too slow to be a good vegetable filter. We cover
all of these topics BTW at great length in our new book coming out this spring
called "Reef Invertebrates". Lots of information on the site here too
as you know :) >
Or just buy a few canister filters and let my Nitrates go through the roof like
my friend (haha just kidding).
<I'd recommend a deep sand bed refugium instead on a RDP cycle with either of
the two above mentioned algae>
Second question - I have bubble algae and this stuff is hard to get
rid of.
<do you mean Valonia type algae or slime algae with bubbles in it?>
My pet store said it is a bacterial algae and if I treat my tank with
Maracyn it will take care of my problem.
<Please DO NOT do that!!!!! Your LFS is misinformed. Even if this growth
was/is Cyanobacteria... drugs treat the symptom and not the problem (nutrient
control... leaching from the algal filter or just a lack of good skimming
(daily) likely). Maracyn will also kills massive amounts of desirable fauna>
I need the truth, so I come to ask your crew for advice.
<if it is a slime algae with bubbles it is also a sign of poor water flow
(you need say 20X per hour here) and supports part of my theory for why your PD
tangs don't fare well>
I don't want to lose my whole tank because it crashed
by bad advice from a 16 year old at the store.
<good to hear of an educated consumer doing homework!>
Final question - 4 line wrasse - I have had a 6 line wrasse live in my smaller
reef tank (75 gallon) and It lived great. I moved it to my (150 gallon fish only
tank) and put a 4 line wrasse in the reef tank. It died! I have since killed two
more. They just don't seem to live.
<hmmm... antibiotics as advice for algae... numerous dying PB tangs and
wrasses... ya, know... I'm starting to wonder about the LFS you shop at
<G>? Also... putting good money on a bet that you don't QT fishes either
bud. Critical to do so!>
Are they more sensitive than the 6 line, or am I just getting bad fish?
<bad fish and or bad husbandry (lack of QT to stabilize and strengthen new
fish)>
Thanks so much for your time, Paul
<our great pleasure. Anthony>
