As the title states, im upgrading from my 75 mixed to a 225 in a couple months. Right now the 75 has 150W DE Hqis that badly need new bulbs.

Rather than replacing the bulbs im thinking about buying a new fixture that will move to the 225 (31" deep) when the times comes. Im thinking a 250/400. This will be a single fixture on a lightrail.

A couple questions:
Would a single 400w DE on a lightrail bleach/shock my corals in the 75 after being under the 150's? I've heard people state that since the light source is not continuous that bleaching is not much of an issue when using lightrails.

What would be a good bulb to pair with a new Icecap ballast. I do have Icecap actinic supplementation also.

Thanks.
