I am servicing a 150 gal reef 28 in deep 72 in long w/3 250 W MH, no chiller. The temp is running mid day 84.5. There are no sps corals that need the MH only one orange monti cap frag. I have suggested changing the MH to T5’s. Would this help the over heating? And do T5’s use much less electricity?
Thanks
