I eventually want to have about 100 pounds of live rock so that's almost 2lbs of rock to a gallon i have two orange fire fish and some turbo snails and red crabs and a coral angel beauty fish right now. so after i get the rock where i want it, then i want to start a reef of some anemone's, polyps and soft corals... I belive that the bulbs in the PC fixture are GE (general electric?) they are 55 w a piece i will probably upgrade these. to what I'm not sure. should i put two 10k in the PC and then run the moon lights on the reg fixture. for right now i want to put that PC to work so your suggestions would be key.....
