BigMac, you know a lot about MH, what do you recommend for a bulb, and how often should they be changed?
I have softies, 1 trumpet and 1 brain now. I want to be able to have higher light hard corals and maybe a few SPS and clams. It's a 125 gallon with 640 watts VHO now. I'll probably keep the actinics if I make the move to MH.
I was thinking about a dual 250 wat for the ends and a single 400 watt in the center.
Also, will this be too much light for what I have now? Stuff seems pretty happy.
