Question for lighting experts....I have a 90 gal (48x18x24). I was running 2x96 watt retrofit with reflector with so-so results. I added a 2x250 watt M.H. set up into the canopy, and changed the P.C. bulbs to both actinic. The tank looks great, and my chiller keeps the heat under controll, but is this a bit overkill? should I get rid of the PC's? and get different MH bulbs? (they are 10k). any advice would be appreciated!
