hello all,
ive got a 90 gallon saltwater tank with glass tops on it. im looking at light fixtures now and im considering a dual 150w metal halide only fixture. my concern is heat. what are your thoughts on this subject?
ive got a 36" 4x39w t5ho on it now that is sitting directly on the glass and it will raise the temp about 1-2 degrees after being on for 9 hours. the fixture im looking at has legs on it that will raise it from the glass about 3 inches.
mostly concerned with the heat of it all. if it makes any difference they are 15k double end bulbs. also, how do 20k bulbs look?
thanks!
