I am in the process of converting my 125G FOWLR
to a reef tank. I just upgraded my lighting to 4 48" VHOs. The problem is it raised my temperature in my tank to about 84 degrees. It used to be consistently at 80 or 81. What temperature is too hot for a reef tank with some fish? I have a clown, goby, dwarf angel right now. I do not want to spend the money on a chiller so my question is what fan would be the most efficient to cool down the lighting? The tank is 60" long and I was looking at 3" or 4" clip on fans. Does anyone have experience with these and what brand is the best? Thank you for you input.
