I believe Mike's magic trick is the MH lighting. When I ran my 90g set up it had 2 MH light's on it. Everything looked awesome and the overall health of the tank was great. When I went to the 225g set up, I tossed the MH and went T5. That tank never handle as well.
One day I'll set up another tank. When I do, I'll run the big power sucking meter spinning MH lighting again. But I've always been a fan of the hot heat producing MH.
Keep up the awesome good mpcart, glad to see your still rocking it!!
