Here's my problem currently running a 65 gallon reef and fish tank for the past four years. Just bought a 210 gallon i'm making my own refugium out of a 75 gallon tank. I've been reading a lot on led's and most people are saying Orphek system is the way to go. Yes more expensive up front but long run pays off. Metal halide everyone knows about whats your guys opinion and experience. Thanks:grumble:
