I just recently acquired a 90 gallon tank that came with an ice cap ballast that has four pairs 48" T8 sockets. I was not sure if the lighting worked so I bought 2 6500k bulbs to test, and it works. This is going to start as a FOWLR
tank and if I move to corals I will upgrade the lighting. In the mean time I'm not sure what other two bulbs to get. Here are my ideas: 1 10,000k and 1 actinic, 2 actinic, 2 10,000ks, 2 6,500k, or 2 50/50s. I want to know what you guys think, please help me out!
