Temperature Control in the RSM 250
I am back again with a question about my RSM. Not stocking this
time but temperature that has me worried. Despite my room being
at 20 degrees Celsius, the tank seems to be at 28 minimum and
goes maybe 1 degree higher when lights are on. Still not stocked
(expect for 1 Percula) but I imagine I do need this down by about
3-4 degrees for a reef setup.
<Yes, 82 1/2 (28 C) degrees is getting up there for corals.
Your 28C temp seems a bit high with an ambient room temp of
I have kind of resigned myself to needing a chiller but before I
put the money down on one, I thought I'd check with you if I
am missing something. I was under the impression that the tank
was usually 3-4 degrees over room temperature but this does not
seem to be my experience with this tank. Moreover, even dropping
the room to 18 does not seem to impact the tank temperature.
Assume the submerged equipment is the cause. My heater is set to
24.5 degrees so never comes on.
< Perhaps a pump is overheating and/or all four hood fans are
operating? I have the same system and with lights on, I could
maintain 80F with a room temp of 76F. Are you running the two
back fans 24/7?>
Is a chiller my only option?
<LEDs would be the other, lower electrical cost plus no lamps
to replace yearly, and you would do away with the heat problem.
This seems to be a common problem among RSM 250 owners. I have
switched to LEDs on my RSM 250, but not solely because of a

in the hobby thanks to you guys.

Re Temperature Control in the RSM 250 9/12/11
for you help James.
To answer your questions below, the fans come on automatically
when the lights are on. Other than that, they are not on. Would
you suggest I run them straight through?
<I'd try it, I believe you will lower your temperature.
The four fans in the light chamber itself helps to keep the lamps
and electronics cool, but it's the rear two fans that will
help lower the tank temperature. There is a switch in the top
control center that will allow you to run these fans
I am still finding my feet with this tank but I do believe it has
a switch for this?
<Yes it does, do read the manual, should state this.>
The hood fans do seem to work just fine with the lights on. The
ones of the right side are the exhaust taking heat away while the
ones in the back pull in air.
The tank is currently 2 inches from a wall. Would increasing the
<No, that is plenty of room for the rear fans to do their
On another note, what LEDs did you use for your RSM? Do they sit
in the current hood or did you have to modify?
<I am actually doing a product review on the Aquabeam 1000 HD
Ultra Tiles which should be published in our WWM Digital Magazine
toward the end of the year. I removed the hood and the fixture
rests in the side wells that normally support the hood arms, no
modifying at all. I will attach a pic taken during the early
stages of set up.>
The thing I like about the tank is its neatness and that's
really what has me hesitant on the chiller.
Cost is a secondary concern. I am already looking at a skimmer
upgrade to the Deltec MC500 which will require me to do some
cutting into the hood.
<I would just remove the center cover which also makes it
easier to do maintenance on the skimmer. Why hack it up, the
skimmer is still going to stick out above the hood. My opinion is
that you would be wasting your money here, especially considering
the cost of the Deltec MC500. Although the Deltec is an excellent
skimmer, I'd find it difficult to justify spending the 500
bucks for one. The skimmer that comes with the RSM 250 is very
capable skimmer once it is tuned in, and will process four times
the tank volume per hour.
It is important to maintain a water level about half way up in
the water level window.
I get a good amount of waste weekly with mine. I also use

high grade carbon, ion exchange resins, and ferric oxide to
Thanks for the Red Sea contact. I will write to them and seek
their input as well. Out of curiosity, did you go with the white
or the black?
<My wife went with the black, I wanted white. :-))>
I chose the white (hesitantly) and am loving the colour.
<Ditto. James (Salty Dog)>
Re Temperature Control in the RSM 250
You, my friend are a genius!
<A far cry from that.>
It was so obvious; I can't believe I didn't think of it!
Having the fan run did the trick from the looks of it. Woke up
today to find the temperature at 26 C proper! Never been that low
before. Thanks so much!
Now I just need to see what happens when the
lights come on and that might well be the temperature issue
The compromise of course is that I will now have a lot more
<To be expected. With the LEDs, I run no fans and top off
daily with a quart of RO water.>
From losing less than one measure in the water level monitor
window, I lost 2 overnight. No worries about topping off each day
though. Much easier to solve.
Do you run an auto top-up or do it manually.
<The old manual way. You still have to fill up the supply
water for the auto top off, so........>
I am thinking manually for now. Is there any potential concern
with pouring the fresh RO water into the main tank slowly?
In my other tank I have better access to the built-in sump so
easier to pour it there.
I see your point on the skimmer. Since I am planning to stock
light anyway, perhaps it makes sense to take the stock skimmer
out for a proper spin before I look at an upgrade.
<The skimmer does take some time to "break in"
before better performance is noted.>
Thanks for the tip on the Chemipure.

Lighting System Causing Temperature Problems (Red Sea Max
130d) -- 05/21/10
Thanks in advance for your guidance.
<<Welcome, in advance>>
I am currently cycling my first tank. It is a Red Sea Max 130d.
<<Neat looking little systems>>
It is a 34 gallon tank. I am having problems with temperature
fluctuations caused by the lighting. This system uses 2 55watt T-5
compact bulbs. I started with a 10 hour on 14 hour off light cycle.
<<This is fine'¦what I would do>>
This caused a temperature rise from 77F to 80.5F.
<<Mmm'¦not 'all that bad'
considering'¦in my opinion>>
I then attempted to use the supplied optional cooling fan but the water
still rose to 80F.
<<But still, a 0.5 degree drop'¦this is of
I tried breaking the light cycle into half, 5 hours on 5 hours off 5
hours on 5 hours off.
<<Depending on your livestock this 'may' be
fine'¦but just too 'unnatural' for my
I am now seeing a temperature fluctuation of only 1-1 Â½
degrees Fahrenheit. I am in no way able to afford a chiller right now
so I don't know what else to do. I eventually plan on getting some
soft corals so I was wondering if a split light cycle would be harmful
to fish or inverts.
<<Considering the lighting system, I would suggest the longer (10
hr) 'on' cycle to allow the corals to 'maximize' the
available light output. The temperature swing and max-temp you describe
is workable in my experience. Do utilize the cooling fan'¦and
try leaving the front opening 'up' to facilitate air movement
and some evaporative cooling>>

Red Sea Max Reef Systems../Tank Selection
Hey guys and gals,
Short and sweet today.. what are your thoughts, opinions on these Red
Sea all in one saltwater setups? There is a 65 gallon that looks pretty
good. I live in a small apartment and these seem convenient. However if
they are no good it's a moot point.
<I've heard nothing negative about them. You may want to read
the customer reviews on Marine Depot's site. Look here.
Thanks so much for your time.

New Aquarium/Turn Key Aquariums 3/27/09
I wrote before about my 29 gallon and my son's 10 gallon, now
I'm planning to get another tank and give my set-up to my
son's, which consists of the 29 gallon, 15 gallon Refugium, 18
gallon Sump, a skimmer, 2 light fixtures that equal about 206
watts. My question is I was looking into getting the new Red Sea
250 liter tank because of its all-in-one configuration, I was searching
the website to see if I can find any links on all-in-one tanks but, I
could not find any. Is there any information on another company
that has an all-in-one system that I can look at an compare the
Or should I just try to build one with my budget of 1,800?

Recommendations on a 30 - 40 gallon reef tank, all-in-one
commercial set ups 10/6/08 Dear WetWebMedia Crew:
<Kevin> I am getting back into having a marine aquarium as my
kids are now beyond the "throw things in or at the tank"
stage. My last tank was a 120-gallon reef tank that was thriving thanks
to the information on your website and Bob Fenner's excellent
"Conscientious Marine Aquarist" book, but I had to take it
down and give to someone who could use it when my little boy started
walking; big glass tanks and 2 year old throwing things were a concern!
Now that both my boy and girl are beyond this stage, I am ready to
start getting back into the hobby after a 5 year absence and show my
kids how to take care of marine animals. <Ahh!> I am planning to
start with a micro-reef and wanted to know your thoughts on the various
all-in-one systems being sold, specifically the Red Sea Max 34 gallon
and the Deep Sea Aquatics Neo-Nano products. <These
"units" have REALLY improved. Not so familiar with the latter
line, but Red Sea's are very nice, complete, good, working gear>
I like what I have read about the Red Sea Max, but I am a big fan of
having a separate sump and using the Aqua C EV series of skimmers,
which the Neo-Nano would allow. If you feel there are other models of
this category of tanks that I should look into, please let me know.
<Have just looked at Deep Sea's on the net, think this can be
made to work... given your background in marines> As for the
bio-load, I plan to keep primarily invertebrates, with a couple of
fish. I had good success with T. derasa and Squamosa clams, and would
like to keep a T. Squamosa in the tank, with some smaller hard corals
and snails. Fish would be gobies or blennies. i am a big fan of
invertebrate tanks; I grew up in Hawaii and had several marine tanks
with Cone shells, cowries, sea cucumbers and various other animals we
caught on the reef flats east of Diamond Head. <A beautiful spot...
when the swell is down!> Thanks in advance for your advice. Kevin
<Welcome. Bob Fenner, a hu'i hou!>
Re: Recommendations on a 30 - 40 gallon reef tank
10/6/08 Bob: <Kevin> Thank you for the information.
<Welcome> Now I just need to find a south Orange County/CA
tropical fish store that carries these tanks! Take care, Kevin <Mmm,
I'd write the manufacturers through their websites... ask them
whereabouts you can see, buy them. BobF>
All in one tank... Red Sea Max...
3/12/08 Hey crew.. <Rick> Was wondering if anyone of you, or
any of your readers had any experience with this "Max Tank"
saltwater setup? <Have seen it...> There is a LOT to be
suspicious about with this thing and it's only 34 gallons which is
very small for saltwater, but while I wait for more space, was thinking
this could make for a pretty cool nano tank.. if it's a good
product of course. Here is the link..
http://www.thatpetplace.com/pet/group/3973/product.web Thank you so
much for your time and this amazing site. Rick <IMO is a very nice
unit altogether... Bigger, better than smaller such "all in
ones". Bob Fenner>
Adequate lighting for an anemone Red Sea Max
(34 gallons), Enough lighting for an Anemone? - 1/31/08 Hello
<Hello Art, Brenda here> After 40 years of maintaining freshwater
aquariums I finally took the "plunge" and decided to try
saltwater. The impetus behind this decision was the introduction of the
"plug and play" self-contained Red Sea Max. I have had this
unit for three weeks and am quite pleased with it, so far. In an effort
to get up to speed, I read Fenner's book and found it superb. I
have also been on your site many times and found it to be both
enjoyable and quite instructive. <Good to hear!> Yes my RSM tank
(34 gals, including a 5 gal filtration area) currently has 40 lbs. of
live rock and 80 lbs. (4 inches) of substrate. The unit has 2 55watt T5
power compacts including 10k actinic lighting (4 watts per gallon).
Like many others, I have always been intrigued by the symbiotic
relationship between clown fish and anemones and would want to include
an anemone in the tank, sometime in the near future. Everything I read
"seems" to suggest or at least is not clear to me, that this
lighting is not adequate for an anemone. The Red Sea literature
suggests otherwise. Therefore, I decided to ask the experts directly.
Is this lighting adequate for an anemone (E. quadricolor perhaps)?
Thank you. Keep up the great work. Art <This lighting is at best
border line. The watt per gallon rule is not a good rule of thumb to go
by. This tank is nearly 20' deep. An anemone would have to remain
high in the tank, and may need extra feedings to supplement the lack of
lighting. Also this T-5 lighting does not have individual reflectors.
Without individual reflectors, this lighting is comparable to PC. I
personally would not keep an anemone in this tank. Your tank also needs
to be an established environment before adding an anemone. This takes 6
months to a year. Brenda>
Re: Red Sea Max (34 gallons), Enough lighting for an
Anemone? - 1/31/08 Hi Brenda, <Good morning Art!> Thank you
for your immediate response. <You are quite welcome!> You
confirmed what I feared was the case. Do you folks have an opinion as
to this product (considering its small size) providing a viable
environment for a mini reef? Assuming, of course, that one chooses the
appropriate corals and invertebrates and maintains a light fish load.
<I do not have any personal experience with this product. However,
looking at the specs I would say it is an average, possibly above
average, all in one system. My main concern would be as to how well the
skimmer produces. I do suggest keeping easier corals. Soft corals will
do fine here. Mushrooms, Leather corals, Palys, Xenia, Kenya Tree, and
Anthelia, to name a few will work here and still give you a beautiful
display. These soft corals have also been known to be a substitute host
for clownfish. So you may still be able to get your symbiotic
relationship that you were hoping for.> I must say that the
"crew" is terrific and you all make this hobby so much more
enjoyable and understandable. <Thank you! It is always nice to hear
positive feedback!> I will make every effort to support the site.
<Great!> Thanks again. Art <You're welcome and good luck
to you! Brenda>
Red Sea Reef Max vs. C.A.D. Aquarium 1/25/08 Hi,
<Hello Phil> I am new to saltwater and contemplating purchasing a
Nano tank. I like the idea of an all in one tank, they also fit my
space needs. I was originally set on the Red Sea Max and then someone
suggested the new C.A.D. 39g set up. Reading the specs on both it is
difficult for me to determine the best. I thought I may ask for help
from others who have experience. Which company has the better
quality/customer service etc... Any help comparing the two and guidance
as which way to go would be a great. <I'm not familiar with the
CAD product, a search didn't help me much with product info.
I'm thinking no protein skimmer is provided. The Red Sea on the
other hand provides everything, a true plug and play system, and, the
lighting provided, should fit the needs of most if not all light loving
invertebrates. As for customer service, I know first hand that Red Sea
is excellent in this regard. If it were me, I'd choose the Red
Sea.> Thank you, <You're welcome. James (Salty Dog)> Phil
