I may have made a mistake, I saw a deal that was amazing. I bought a 20" MH 175w with 2x24w CF for a 30g reef tank that i'm going to be starting. Unfortunately I didn't research this enough judging by the feedback that I'm getting from everyone on here. I'm just looking to see if anyone has any good experience with these, or if they are just POS. I'm already thinking about sending it back and I haven't even got it yet. Any help would be appreciated.
