I have installed one fan on the metal halide stand blowing horizontally towards them. The fan is super loud. Annoying. it's been keeping temperature around the 80 mark but I have also noticed that my T5 actinic light stand is super hot. Both internal fans are working and clean but they're still hot.
I'm at a point I'm willing to buy a whole new light system that will do the job in my 90 gallon reef tank. I got polyps, mushrooms, anemone, clam, devil hands, kenya trees. what type of all in one lighting system would you recommend.
