Actinics are on from 8am - 10pm.

I'm thinking you're right with a change every few days instead of every day.

Ok, then I think your best bet is what I said here:

It causes a lot of harm if you push it too fast. It's not a bad idea to raise the light as well as other's have suggested.

I just recently upgraded from T5 to 2 x250 MH. I started with a 12 hr actinics and 2 hr MH per day and increased the MH 1 hr per week. Also I moved some of the corals like zoos and Frogspawn lower in the tank. No ill effects at all.

Thanks. Height isn't an option, they're fixed in the canopy. I'll slowly raise the period over a couple of weeks.

Get some mesh material used for window screens and place a few of layers on top of the tank. Remove a layer every few days or so until acclimatized.

He said screening wasn't an option in his first post.
