Too small to
Aquapod Lighting 11/06/09
< Stan >
I have a 24 gallon Aquapod with a 65w PC. Tank has LPS, candycanes,
hammers and frogspawn.
< I would look into upgrading. >
I was thinking of adding another 65w.
< Good idea! >
As I have been searching around I started to consider T5's.
< Better idea!! >
I found a nice 96w T5.
< Should do nicely. >
What I can't seem to find is life expectancy of a T5.
< Manufacturers suggest from 10000 to 15000 hours but I would start
replacing them at about 15 months. With the actinics being the last
Is it similar to PC's?
Or how about MH at 150w (here we go, this hobby always seems to cost
< I would stay away from MH. They can lead to heat issues in
smaller, nano sized tanks. >
Then I might have a heat problem.
< Very possible. >
Do MH bulbs just burn out?
< No, as they age they shift spectrum. Can cause nuisance algae
They are reported to last much longer than fluorescent. Is that too
much light for LPS?
< Would depend on the LPS in question but most would do fine with
proper placement. >
Or can I have them on for less time during the day?
< If you are set on MH I would look into one of the MH combo
Limiting the MH to about 4 hours and using the supplemental lighting to
finish up the lighting period would help keep the heat manageable.
< For a tank your size, T5s are the way to go. More efficient , more
bulb options, cooler running... GA Jenkins >
Should I Change My Setup/Reef Lighting/Growing
I have a 24 gallon Aquapod and have been using it for 10 months and
have been satisfied with it. It came (bought it used) with a hood with
PC lighting (64w) and an alternate glass cover to be used for other
It also has a hang on skimmer. I had a 24 inch PC that has 65w so I
decided to use it with the glass cover since I could not use the
skimmer with the regular hood.
The skimmer hangs on a back compartment so that you can not use the
hood. It may not be the worlds greatest skimmer but whatever it does
collect I am glad is not in my system.
<Any skimmer is better than none.>
The main difference in the lighting is that the one in the hood is 12
inches and mine goes all the way across.
<Staggered lamp placement?>
The tank has one Candy Cane colony of about 30 heads, a hammer of about
10 heads, another hammer (not branching) about 5 inches long, a Favites
about 4 inches across and a couple single heads of frogspawn. And in
the fish category I have a Spotted Cardinal, a Neon Goby, a Clown Goby
(just got him, yellow, about half an inch and really cute and doing
well) and a Chalk Bass.
<Tank a little smallish for the cardinal and bass.>
And some snails, Astrea, Cerith and Nassarius. Algae is there but
manageable. Glass needs to be cleaned once in 2 weeks and even then it
is not really bad. Some hair algae spots and the back has some type
growing on it looking like fuzz.
Last night I broke my glass cover as I was trying to clean it. So my
question is do I simply get a new glass cover or should I remove the
skimmer and use the regular Aquapod hood. It looks much neater with the
hood but will I be giving up too much?
<Don't think so, both lighting units are 64 watts and should
fill the tank with light.>
Also, would my setup benefit from more light. My corals are ok but they
do not grow new heads.
<Definitely, the Candy Cane, Torch, and Frogspawn Corals all require
I wouldn't consider 64 watts moderate, only averages out to a
little over 2 1/2 watts per gallon which
is fine for softies, but for LPS corals in a 20" deep
tank....Mmmm. May want to search BB's for a
clamp on 150 watt HQI or if room permits, another 64 watt PC strip
<You're welcome. James (Salty Dog)>
Lighting and DSB'¦T5 vs. MH --
I am looking into upgrading from an Aquapod to a larger system. The
wife has 1 unchangeable limitation of length being a maximum of
<<I see (dang women [grin])>>
So what I am contemplating is either a 36"x24"x24" which
is 90 gallons or 36"x24"x18" which is 65 gallons.
<<Same footprint, eh'¦might as well go for the added
volume then, especially if considering a DSB>>
Also she wants a canopy for her own aesthetic reasons.
I would like to be able to keep clams and various types of corals. I
will be using at least 1.5lbs per gallon of LR,

needed) to keep the display from being overcrowded re>>
I would rather avoid a chiller.
I live in Orange County Southern California and the normal temp is
under 90 most of the time. I do have AC in the house. I would also like
to keep my electric bill down.
<<Wouldn't we all'¦>>
I would rather have the 90 gallon tank of course and this brings me to
my question. If I go with the 24" deep tank and 4" DSB would
a 8 X 39 Watt T5 HO lighting system with 4 10k bulbs and 4 actinic be
enough to penetrate <to> clams <and> corals at sand level
or would I have to go metal halide?
<<With some caveats, yes'¦ I would recommend a 6 to 2
ratio of 10K and Actinic bulbs. I would also suggest

lighting option you choose>>
Also if T5 setup is ok will it penetrate <to> the DSB?
My last question pertains to lighting as well; depending on what light
setup you recommend the canopy is available in 2 different heights

lets you mount these closest to the water's surface (ideally,
within 3-4 inches). If you choose metal halide, either canopy will

From 10 gallon to 24 Aquapod, 1/22/09 Hi
Crew, <Hello> My 10 gallon (over 6 years old) has been very
successful thanks to the crew. It has sand and rock , a clown goby (5
years), spotted cardinal (5 years) and neon goby (2 years) plus some
snails. <Nice> Also have 65w PC's and candy canes. Filter is
a mini penguin with a bio wheel. I will be closing down the 10 gallon.
The Aquapod footprint is not much larger than the 10 gallon. The length
is about the same. The width and height are larger. It has 30 pounds of
rock (cured) and will be adding 1-2 inches of live sand shortly. The
Aquapod just has a glass top so I will use my PC lighting. I tried
buying an Aquapod cover with PC lighting but they do not sell it
separate. I will try to place the coral along the path of the light and
within the same distance from the light that it was in the 10 gallon.
<Good> I plan on adding a firefish and possibly one more, a chalk
bass or gramma. <I would not, the bioload capacity of the AquaPod is
not going to be significantly greater than the 10G due to its
depth.> But the gramma may be too much for the firefish to handle.
<I would think so, especially in this sized tank.> The filter is
simply a pump pulling water out of the tank through a sponge and
shooting it out like a powerhead from 2 nozzles. The water flow is much
stronger than my 10 gallon. I will be placing carbon behind the sponge.
Any suggestions would be appreciated. <Adding a skimmer is always a
good idea.> I am debating whether to use my 5 year old rock from the
old tank. It is one piece about 10-12 pounds. I know it has life inside
but it also has pest algae on the outside on about 1/3 of it which is
impossible to get off other than chiseling it down. Is it worth it?
<That depends on you, will save some money and bring in established
rock, but the algae will most likely continue unless physically
removed.> Thanks, Sam <Welcome> <Chris>
Re: From 10 gallon to 24 Aquapod 1/22/09
Hi Chris, <Hello> I do not understand the statement highlighted
below. <Can't see the highlights on our mail system.>
Isn't the bio load dependent on the volume? <That is only one
factor, and a small one in my opinion. Surface area for gas exchange
and the footprint for available territory, which just about every reef
fish will attempt to establish, are much more limiting than volume of
water. Even if you massively overfilter a tank to provide good water
quality it you can still run into problems if you do not provide the
necessary "living space" for the fish's needs. Fish need
lateral space, which the cubic design on the Aquapod does not provide a
whole lot of.> Thanks, Sam <Welcome> <Chris>
Re: From 10 gallon to 24 Aquapod,
1/26/09 Hi Chris, <Hello> Thanks. I guess I should have
asked before I bought. Since I only plan on having the very small sized
fish it should work out. <Depends on the fish, many would easily try
to claim the entire tank for themselves, even if they are small.>
One more question regarding moving to the new tank. The rock in the
tank was cured before I bought it and I tested the water and both
ammonia and nitrites are zero. Does that mean the rock can handle a bio
load or do I need to cycle the tank (fishless way) before I put in my
fish. <I would still give it time to cycle, it is impossible to tell
how much bacteria is in place, and adding too much too fast could
overload it quite easily. Besides, time to cycle allows for the critter
population to establish itself before predatory animals are added,>
Or maybe take a rock from the current tank and place it in the new one.
<Would help.> Thanks, Sam <Welcome> <Chris>
Lighting, small SW, and wet-dry filter
media 1/2/09 Hi Crew, <Hello Sam, Minh at your
service.> I have a 10 gallon with 65w (10k daylight) pc lighting
that is over 5 years old. I am moving up to a 24 gallon Aquapod and
would like to use the same lighting fixture. <Congratulations on the
upgrade.> The standard Aquapod cover with PC lighting is 64w (32 10k
and 32 actinic). My corals are just candycanes (probably close to 100
heads in total). My watts per gallon will be going down but does it
really matter as long as I concentrate to corals along the light path
and move them to the upper half of the tank. Will my current lighting
be better for the corals than the Aquapod or does it not make much of a
difference. <The "wattage per gallon" rule of thumb has
really hindered the way aquarists look at lighting properly. Instead,
we should look at the units of lighting produced by a particular
lighting set up in terms of PAR (Photosynthetic Active Radiation) or
PUR (Photosynthetic Usable Radiation) - detailed explanation of these
terms can be found on Sanjay's Lighting Website
(http://www.manhattanreefs.com/lighting). In your particular case, you
are spot on in pointing out that although the watts-per-gallon ratio
goes down as your water volume goes up, the PAR/PUR units will remain
the same as the lighting fixture is the same. Furthermore, you've
pointed out a great strategy in coral placement and aquascaping to
maximize light penetration in a taller tank.> A second question
relates to biological filtration. If I have 25 pounds of live rock,
sand and a sponge filter media is that sufficient. I have read about
the problems of ceramic or other balls used to increase the biological
population and would rather not use them if the problems outweigh the
benefits. <In terms of nutrient export, the problems can outweigh
the benefits. Here is an excerpt from an article explaining the process
in detail, "Nitrate in the Reef Aquarium"
"Such filters do a fine job of processing ammonia to nitrite to
nitrate, but do nothing with the nitrate. It is often non-intuitive to
many aquarists, but removing such a filter altogether may actually help
reduce nitrate. So slowly removing them and allowing more of the
nitrogen processing to take place on and in the live rock and sand can
be beneficial. It is not that any less nitrate is produced when such a
filter is removed, it is a question of what happens to the nitrate
after it is produced. When it is produced on the surface of media such
as bioballs, it mixes into the entire water column, and then has to
find its way, by diffusion, to the places where it may be reduced
(inside of live rock and sand, for instance). If it is produced on the
surface of live rock or sand, then the local concentration of nitrate
is higher there than in the first case above, and it is more likely to
diffuse into the rock and sand to be reduced to N2." I My current
10 gallon has a Penguin mini power filter with a bio wheel and I never
found a spike in ammonia even when large snails died (which I did not
remove because all critters deserve a treat once in a while). <It
sounds like your 5 year old system has reached a natural equilibrium. I
suspect your new set up should fare well based on the experience
you've gained with your current set up.> Thanks, Sam
<You're welcome. Cheers, Minh Huynh.>
Re: Lighting, sm. SW 1/4/09
Hi Minh, Just wanted to know if there is any real real difference
between my lighting and the one in the Aquapod as noted below. <Sam,
the performance should be similar between the stock Aquapods 2x32W
SunPaq and your 1x65W Daylight. Obviously your 1x65W Daylight would be
much brighter directly under the bulb as the Aquapods 2x32W splits
between Actinic and Daylight SunPaq bulbs. However, the light spread on
the 2x32W SunPaq has more coverage suitable for a cube tank's
dimensions. Like you mentioned before, creative aquascaping along the
path of the 1x65W lamp is an option. Another option is to add another
1x65W lamp using a retrofit kit for additional coverage as your corals
grow.> Thanks. <Hope that helps. Cheers, Minh Huynh>
Aquapod Pump/Water flow 4/11/08 Hi there, <Hi
Alex.> I have one simple (hopefully simple) question. <OK> I
currently have a Hydor Koralia 1 providing the majority of water flow
in my 12 gallon AquaPod as well as the output from the filter that came
with the tank. What I am looking for is something that will change
direction and not constantly flow water in the same pattern. Is there
something out there that perhaps toggles it's direction
continuously so as to minimize the "dead spots" for grunge
and build up? <Hmm, yes. SeaSwirls, Ocean Motions, SCWD, and WavySea
are a few that work well. They are also large and expensive for a 12
gal (except maybe the SCWD). For your output on the pump look at the
Hydor Flo Deflector. It is not the best, but it is cheap and works. You
just need to clean it as part of your regular maintenance. You can
achieve about the same results by directing the powerhead and pump flow
at each other. This will give you a varied flow.> Any suggestions
would be appreciated. Thanks, Alex

Starting an AquaPod reef... 3/14/08
Hey Crew! Quick question...I've got a 12 gallon nano reef, up
and running for 2 months now with one small clown, blood shrimp
and 4 blue legged hermit crabs occupying this tank. Prior to
putting the shrimp and clown in the tank I did my water tests and
everything was perfect. Since putting in the shrimp and the clown
and eventually the 4 crabs (who were supposed to be a clean up
crew but as far as I'm concerned they make more mess than
they clean - I'll be getting rid of them tomorrow and
replacing them with smaller blue or red hermit crabs) my ammonia
has shot through the roof to 2.0. <How much did you suddenly
start feeding the tank when you added the livestock? The
combination of the added livestock and food might have been too
much too soon.> I know the obvious way to bring the ammonia
down is to do more aggressive water changes or perhaps more
frequently, but as I experienced last week; when pouring in the
salt due to it's small nature of the nano the corals get
burned from the contact with the salt (mental
note....pre-mix)...can you recommend any piece of equipment that
can help me with keeping the ammonia down? If it was a normal
setup I would immediately purchase a protein skimmer but as I am
now realizing, these nano tanks aren't all they're
cracked up to be <Bingo. They're often without adequate
filtration.> as there is NO space for a skimmer or at least
not one that I can find. Any of the nano skimmers I have found
involve me altering the hood which I am not confident in doing.
Is there a nano skimmer out there that will help me, perhaps if I
threw in a mangrove plant? <A mangrove won't help. It
wouldn't do well in such a tank anyway. Honestly, there's
not a whole lot you could do that wouldn't involve altering
the hood to add filtration or drilling the tank to add a sump.
This is the trouble with nano tanks systems. If you don't
want to alter the tank, you'll have to find a way to do the
heavy, frequent water changes (i.e. pre-mix your water,
etc.).> HELP ME PLEASE!! Thanks so much! I've been a
reader for over 5 years now and have enjoyed every minute of it!
<De nada and good luck, Sara M.>
Re: Starting an AquaPod reef... 3/14/08 Hi
Crew, <Hi> This is in response to the above heading in
today's questions. The person has a 2 month old 14 gal nano
and has problems with ammonia and one clown in the tank. I
started a 10 gallon over 5 years ago and lost quite a bit of fish
and critters during my first 6 months. Then I found the Crew. I
still have the 10 gallon and 2 of my fish are over 4 years old.
So if you follow the advice of WWM you can be successful with a
nano. And rule number one is patience. You can't load your
system with more than it can handle. <Indeed, this is true of
any tank of any size.> Give your clown a break and ask the
store to hold it for a while. The only reason I am responding is
because the crew has the tendency to shrug off nano problems
because they can be difficult to control. <Hmm, I certainly
didn't mean to "shrug off" the writer's
problem. The person who asked the question said he was reluctant
to alter the tank in any way that would allow him to add
equipment or water volume. He also said he was reluctant to do
more aggressive water changes. Thus, I was at a loss to offer him
any other solutions. Taking the livestock out would only be a
temporary solution.> But if your advice is followed then
people can have a good success rate. You can't cut corners.
The systems are not forgiving. There just is too little water to
dilute problems. <Very true and I thank you for writing in
with your support/advice. In my opinion, the best way to keep a
nano tank is with a large sump hidden underneath. It might be
"cheating," but it works. ;-)> Thanks
