I may be a bit oversensitive about things, but typically when I buy a coral from the store I will ask what lights are over the tank, so I will know their output versus what I have at home and position it in the tank accordingly. Except I'll never put it in the top at first, start it out half way up and then slowly move up over the course of a few days or a couple of weeks if it needs intense light.

Actually I did have it almost to the bottom, then about halfway and then to the top but I probably moved it too quickly. Thanks for the input.

The problem with asking about lighting over the tank at the store is that the corals prob haven't been there that long (usually less than a few days). This really isn't any time for adaptation. It used to bug me when stores would get in a big batch of corals (predominantly LPS) and then blast them with 250 5500K watt MH, sitting 20" above a tank, only 12 " deep. this after the shipment was boxed for 2 days in pitch black. Plus you know the lighting at the exporters was minimal. We're talking about animals that have been deprived of adequate lighting for upward of 2 weeks. Gee I wonder why they bleached - then fell apart? I like Brian's method of starting everything out low & moving them up. You can't hardly go wrong with gradual acclimation.

dj, good point about the lack of light and not being in the store very long, hadn't really thought about that!

A technique I have heard of using is with screens (like the kind used for screen doors). Just put several layers over the lighted area just above the targetd coral and then every few days or week, remove one layer. Over time it will get used to the light filtering through.
