Bio-cube Heat Problem

rondog · 04-24-2007, 05:51 PM

I have a OCEANIC BIO-CUBE 29 and seem to be having a little heat problem. My ambient room temp is 75 Deg. F, I have a floor fan blowing towards the tank but still the water temp will rise to over 80 Deg. F during the day. I have a small computer fan I have placed on top of the rear service opening and this will bring the water temp down to about 75 Deg. F Is there a fan designed which would fit in the rear servie area which would allow the cover to be lowered? I bought a 3-1/8" x 3-1/8" fan which produces 32 cfm but will require a mounting bracket design. thanks in advance for any help.

I keep my tank at 79-81.. 75 is to cold... If it has a cover on it open it up.. The fans are the right idea though.

I have seen some VERY impressive tanks fully stocked at 75 and even less. I watched a video of one that's over 6 years old that's got just about ANYTHING anyone would want in a full REEF tank and the owner said he keeps it at 72 Brrrrrr degrees and that's where he has had the best luck.It's an amazing tank to view and behold. That being said (not to contradict or ruffle feathers miss blue as it's not intended towards you at all just adding to the conversation) I think the biggest problem is the possible temp swing of that tank. How much does your temp fluctuate without the fans?IMO if you could maintain a constant temp of 79-80 with less "Stuff" going on (less fans etc to quit and cause a heat spike = crash). My tanks hover around 76- 79 during a normal day including lights. What I did was buy a pair of reliable and accurate heaters and slowly bump them up to 79 so that WITH lights the the temp is maintained at the top of my normal daily swing. I don't check my temp hourly but several times a day and with this arrangement my temps are always dead on 79 and I only have one item to break and it's fairly reliable.

Just an idea that may or may not help. Good luck and HAPPY Reefing!

Sincerely,
Allen

The thing you need to watch more than the actual temp is the temp swing. That is why many people have their fans plugged into a timer with the lights. This way the fans are on when the lights are heating up the tank. Unless you are keeping something that requires colder temps like seahorses 80 is fine for a reef. Just try to minimize the temp swing and you should be fine.

Temp variance is from 75 to 78 on a bad day. I mentioned 80 and then realized that I had the patio door open which did not help things at all.
the tank is far enough away from the sliding do so that outside or direct sunlight is not a factor on the tank. I have just received shippment of a light upgrade on my BC 29. It will go from 72 watts to 144 watts of PC when it is completted. Kit includes upgraded high output fans. I purchased the upgrade from NANOTUNERS.

thanks for everyones help and advice

I just did a lighting upgrade on my aquapod and ran into some heating issues as well. I don't know if it would help in your situation but...I drilled some extra holes in the top to increase air flow over the lights so that the fans could pull more heat out. It seems to be helping...about 2 degrees worth.
