If you are going to go with 2 400W MHs, don't even bother with 2 T5s. Whatever the color of the MHs, that will be the color of the light in the tank. The T5s will make no noticeable difference to the color. You won't see any "pop" from actinics if that is what you are shooting for. IMO even those fixtures with 250W MH and 2 actinic T5s are a waste. I've ran a 250W MH with two T5s on the Icecap ballast and barely noticed a change to the color. So yeah, no point.

There is definitely no need for such high powered lighting over a 75 gallon tank. IMO a lot of people go way overboard on the lighting, even with "light-loving" corals.
