yes, a chiller, or some fans blowing across the top of the tank or sump.. that creats lots of evaporation, so auto top off becomes a factor. I have seen some beautifull reef tanks that are shallow like your tank will be lit up with T5's and there gorgeous. I have a 240 gallon tank with 4 250's. If i didnt have temp controll it would over heat, and this is in a cool basement in colorado.
