Ive been thinking about lighting alot here lately and i was just wondering how many 96 watt pc bulbs would i need on my 125 gallon tank to keep LPS. I really like them alot more than the SPS anyways and if i can get by with it i dont see why i need to have MH IF i dont really need it...If MH is still the best way to go i will probably do it but i am just wondering if i could get away with like 4 or 6 96 watt PCs.......It is like 15 or 16 inches deep to the top of the sandbed.
