I am getting my 180 gallon going and need lights for it. The dimensions of my tank are 26" tall x 67" long x 24" deep. I am pretty much sure that I want to go with 3 mh's, but not sure if I should go with 3 250w mh's or 3 400w mh's. This will be my first reef tank so I cant really tell you what I am going to keep in there because I dont know much about reefs yet.
