I'm planning on getting some new lights for my 70g reef. Right now I'm running 2 175w MH and 1 96w PC actinic. I think I'm going to get the hqi MH/t5 retro kit from hellolights. Anyways my question is, should I get 2 150w or 2 250w? It's about 20" to the sandbed, and I plan on keeping all kinds of corals.
