Fans in canopy

[iechy]

Anyone have any comments about putting cooling fans in their canopies? Willthis keep things cool enough or should I build a higher canopy as well? What I was thinking was putting one fan pulling air in on the left rear and one pulling air out on the right front thinking this would both pull cool outside air across the lights as well as pulling out the hot air caused by them. Any comment or success/horror stories would be appreciated.

You could just use one fan and a vent on the other side. A taller canopy helps allows more air in. A fan is a good thing to help pull unwanted heat from the tank. ALso helps more O2 get into the water.
