Sorry for pulling up such an old post,but I just put 2 55w PCs over my 29g in a canopy and the tank temp. increased by 4 degrees. The back of the canopy is open, but that doesn't seem like enough. It is pretty warm under the canopy. I was thinking of putting in a couple fans. Any suggestions?
Mr. Salty,
How did you wire the fans into the light timer? Are they AC or DC?
Thanks.
