yep, another MH question

[me-n-my-fish]

Putting MH over my 55gal long. Reflector and all. Will 2-175 watts be enuf? or should i go 250 watts? Not really going to keep any diff. corals, but want the ones that i do keep to be happy!

175 should be fine. 1 MH for every 2 feet of tank length/width. I would go with 250 though if you plan on upgrading to a bigger tank so you dont have to go through the process all over again.

Definitly get the 250's unless you think heat will be an issue. But if you can afford a chiller don't worry about it.
