That's rarely a problem. They may not bloom out as much,
but rarely do they really suffer from the increased lighting.

Many a times I've taken corals from low light areas and
put them right under 400watt mh lighting.

It *can* produce a problem, but rarely does.

If you want to play it safe, you can place the corals
lower, and move them up, or reduce lighting , but I'm not
too keen on the idea of the reduce lighting method,
preferring the coral moving method.

Also since you have two 150 watt small point source lights, you can

But if you put corals TOO close to the light, and they WILL bleach...


Yeah, I've heard this. I think there was a recent article in the
"Tropical Fish" rag. They recommended introducing new lightly in
increments rather then just a swap out.

I was planning to radically cut back on the hours of light and then ramp
back up to where I am when I get my new lights.

Don't know if that's necessary, but I figure it won't hurt anything.
