No pro here either, but most palys do not like too intense a light. Many will even develope white spots I think it is where they have expelled their zooxanthellae.
I have had it happen to PE before and when I moved them out from directly under the Mh they regained their color.
Not that this means anything from what I understand too clean of water is not good for them either and too much running carbon can cause them to close up, but I wouldn't personally know, I don't use carbon except for emergencies.
Thanks Mike, I knew most weren't into intense light, but had read the true Armor of God prefers it, so set the plug high. Perhaps these weren't true or perhaps simply too much. I moved the plug lower thinking the same thing, so we'll see what that does. Also like you have seen that they prefer some nutrients in the water column, but with my sump I haven't had any nutrients since about week 3, even when the carbon filter is shut off.
