Need help w bio cube

[vikrant621]

I have a 29g bio cube. I have pair of clown fish and two corals in it.

I having problem keeping the thank cold.
My tank since i got it, it stays anywhere from 80 to 82d

If anyone can help me with how to figure out to keep the temp below 78

that would nice.

Any suggestions?

Which version of the biocube do you have? If it is hqi version you can try removing the glass from the top. If its the PC light version, maybe opening up the lids or sump cover may help. Also having a fan or adding a small sump fan that blows over the top of the water can help lower the tank temp up to 2-3 degrees, but it increases evaporation so you'll need to add more top off water. You can also add a small chiller to the system 1/15-1/20hp unit would work.

My son has the Coralife, BioCube 29 in his room.
We keep the house AC set at 78 but...with the access panels close, the temp rise in the tank.
We turn on the ceiling fan and open up front (feeding) and rear (filter) panels. The temps drop down to 78/79 then.

I'm not sure about vikrant621 but the fans on my son's tank are working but they simply do not move enough air to off set the heat generated by the lights & the pump.

The only reasonable solution in our case was to open up the access panels and turn up the ceiling fan.

<span style="color: black"><span style="font-family: Verdana">I've been running Biocubes and Nanocubes for years and IMO the stock fans do not circulate enough air to compensate for a closed hood with PC lighting. The three options I've tried open the hood, replace fans or switch to LED lighting. The first two both result in increased evaporation, the third works the best but LEDs can be pricy.</span></span>

i got this tank brand new. And yea the fans do work on it but i don't think they take much air out. But they only work when the blue lights are on. They dont work when the regular white lights are on.
I have the new style bio cube the square one. i belive its the ocenic one. I think i will have to check on it when i get home.

Keep both the refugium and feeder flaps open. I keep my tanks at 80-82 anyway.

If you have some time, read this article.

but isnt the tem should be around 76-78 for the corals and clown fish?

you can take the top of and install a pendant lighting system or you can install a chiller of course and the cheapest option would be to freeze a bottle with RODI water and stick in the back of the tank. I went for the top removal on my tank and it now stays 77 to 78 even if the house gets up to 80 but ot do get a lot of evaporation and had to install an ATO system.

"At 76-78 F, for most corals, it is not a matter of how long they thrive in an aquarium, rather it is a matter of how long it takes them to die. Their metabolic rate is dependent upon the ambient temperature and in a tank maintained at 76 F, a coral whose optimal temperature is 84 F, has a metabolic rate less than 50% of normal. Such an animal can barely digest what food it gets, let alone fight off an infection or deal with some other stress"
