I'm looking for MH lighting advise for a 40 gallon breeder. I have a pulse start 2x175 and a Galaxy 2x250 MH ballast and a 1/3 hp chiller. I used both over a 75 gallon with good results but following a move lost most of my corals and switched to a 40 breeder and LEDs which didn't work out too well. The 40 breeder became a FOWLR and I really want to go back to corals. So what should I do should I use the two 175s over the 40 or would 1 250 suffice?
