Yes, the fans go on when the 10k bulb is on and off with the actinics. There are no mods to anything on the tank. It is same as it was in the box. I have a seio pump running on it for flow, other than that, nada for mechanical devices. It is not by a heater outlet or any other hot appliances. I have 3 other tanks (fresh water) in my room, and they do not have heating issues, and do require heaters to keep that at correct temp. (From as small as a 2.5 gallon to as large as a 100g). The nano is running at 80-86
 when lights are on (I have started turning them off because I am worried it will climb to greater temperature). At night it goes down to 78 or 80. Do the pumps in these things cause heat? Would anything else cause heat? Are there water issues that can cause heat???? PS: Bought this set-up at Gold's--Hey Albert any suggestions??? I wanted to put corals in there someday... And by the way: why is my purple coralline algae dying?? I am keeping up with lots of water changes. It mostly is dying where the light hits it and that makes no sense to me. Can you give me a clue? ~~~ugh I feel like my dream is dying  please, need lots and lots of advice here.Last edited by sharuq1; 04-09-2007 at 02:46 AM. Reason: noob

I wouldn't be too concerned about the coraline. You won't get a good seed on coraline for at least two months after your cycling has finished IME. FYI, the nano at the store hits 86 degrees on some days. I'd be concerned if it climed any further, but I haven't had any problems thusfar. Lastly, the SEIO is the last thing I'd dump. More flow = less work  One thing you could try is to just run a room fan against the tank.

Just an update. Switched the actinic and the 10 so fans are running the whole time any lighting is on. It is staying in the 80-86 degree range. Nothing dead yet, so that's a plus. Thanks for the advice!

Mine warms up fast too. I just keep the "feeding lid" open and it stays at a steady 80.

I was chatting with a fellow biocube owner who had the same problem. He found that the one fan was reversed so that instead of one fan pushing and one pulling they were both pulling air in.

I just recently installed the 3.24 lighting mod which increases the output to 72w with no visible increase in heat (although the lighting mod comes with 2 replacement fans and a different heat shield). My BC14 runs at about 78 degrees at night and 80 degrees in the day. I'm using a Maxi-Jet 900 as the only powerhead in the aquarium. Temperature in the house is around 18 degrees celcius.

I have a biocube 14 as well, I keep the temp at 76 with the heater and the highest during the day that it has gotten with the lights on has been 78, I haven't done any mod's to it yet, I did switch the actinic bulb with the 10k (so the fans come on with the actinic) as I have the actinics coming on about an hour before the daylights bulb and they stay on about an hour after the daylight turns off as well. Maybe try setting the temp a bit lower on the heater? I only have a 50 watt heater in mine as well.
