MH wattage & depth
I'm in the process of setting up a new tank, and can't decide which lights to use. The tank will be a mix of SPS and LPS and is 24" deep. I have a 2X400w MH fixture and a 2X250w MH fixture I can't decide which way I want to go. I have been a firm believer that you can't have enough light over a reef tank, currently i'm running 11 watts per gallon. but with the extra tank, cost and heat are becoming a concern. I thought I would throw up a poll to see what others are using.
