Upgrading my 75G from a FOWLR to Soft/LPS and lighting is about to make my head explode. At 0ish, I can't afford to make the wrong decision.\nI'm currently using a Current PC 4 X 65W hood which only gives me 3.5 watts/gallon. The concensus seems to be to upgrade to T5 HO Hood. \nTo get to 5 watts/gallon (I do understand that PAR, LUX, etc is more important than watts, but trying to figure it out that way seems practically impossible) I have been lookoing at T5 HO 8 x 54W that would give me roughly 5.5 watts/gallon. With reflectors and fan, they run like 0. \nThen I read about people that have the same tank as me using only a\nT5 HO 4 x 54W and having good luck with SPS and clams!!!\n \nWhat should I buy?????\n \nMy tank is 48"L x 18"W x 20"H\nDon't want to buy Metal Halides because I don't want to end up running a chiller and spending a fortune on bulbs.
