Too much heat

[Basile]

Hi, i got a biocube 29G. I recently put a fuge in the mid chamber wich usually contain bioballs ; now it contain chio. My fuge light is outside hanging or actually stuck to the transparent back. It seems that the 13w light is enough to rase my temp to 82 at midnight and have my temps controle ringing. Today i'v disconnected my heater and my temps is 77.72, this morning it was 76.1 It is of course summer still. My question is How much fluctation can coral and inverts take in the long run.The hole thing is situated in my PC room , with an A/C and 2 larges windows that give a lot of light so i don't need MH and the extra heat. My pump is a maxi-jet 1200 and a Koraline powerhead at the other end. What do you think.I'm asking because you have more experience than me.Thank.

1 Plerogyra sinuosa bubble coral

Ideally the swing would be in the maximum of 4 - 5 degrees. 76 to 82 is pushing it. 82 is OK, so maybe you could set your heater to keep the tank from getting any lower than 78 or 79, that would be fine. My nano (10gl) occasionally swings from about 82 to as low as 76, even though I try to prevent it, but I haven't had any problems with any of the corals.

My 24 gal NanoCube usually sits at 82 but it does swing back n forth between 79-82 degrees. I have yet to figure out a way to keep it more stable...

Ok thanks.

I'd set the heater at 78-79 Deg.
