175W enough for SPS?
Alright I'm stuck. Again
 Is a 175W MH gonna be enough to have SPS? The tank is only a 20 tall, and I'd rather not have a more powerful light than I need, since I do plan on running them for 8 hours a day. But if I get the 30 tall which has the same dimensions but longer, I might want something more powerful... any thoughts would be helpful.
