Question about cooling t-5's??
Icecap Retro on a 75G. (48x18x20) 4 t-5's and 2 vho actinics. This is in a 8" hood with bulbs 4-5" off the water. Hood has an opening at the rear. I have 2 4" icecap fans that blow into the hood. (one on each side). Should this be enough cooling, or will I need to add more fans?
Edit: I should add that this hood has housed a 6 bulb vho setup for 3 years with no problems. I have one fan on a timer that runs all day. The other is on a controller, and kicks on if the tank goes from 80-81 degrees. It vary rarely kicks on. Maybe 4-5 times a year during the summer. I'm unsure how much more heat the t-5's will generate, and how much cooling they need to preserve their length of use.
