I just bought a frag tank and need to buy an LED light for it. This is my first LED purchase as I've got MH's and T5's on my main tank so I'm hoping for some advice. Ideally, I'd like to buy a lightly used LED off of someone from Reef2Reef but I'm not sure what I'm looking for. My tank size is 30x12x12. My plan right now it to keep primarily zoas, shrooms and lps. At some point, maybe I'll add a few sps frags from my main tank. Any suggestions would be appreciated!
