New to Nanos

[kittyj]

Set up a 12 gallon JBJ NanoCube a couple of months ago, and I'm having a really hard time keeping the temperature controlled. It has reached as high as 90 degrees under the stock bulbs.

I also run a 150 gallon reef tank under 1200 watts of MH, and it stays under 85 with no chiller. Help! Any advice on how to cool it down?

Thanks,
KJ

I have a 24 and I had to get a chiller. I think alot of people do. Either that or they open the lid and use a fan.
