Rapid Tissue Necrosis often starts at the bottom but not always.

Can't really move it down so put a piece of egg-crating across the Eurobrace over it along with 5 sheets of window screen. Think that will help and if so how long should I leave the screen in place (it's also blocking the light for some Frogspawn and a Cup coral?

Mark,
My understanding of the idea is lower light (but not dark) triggers the coral to let zoaxanthelae production increase, since these host algae are not as efficient in feeding the coral in those conditions more are required to do the same job. Basically the coral feeds off the carbohydrates produced during photosynthesis, when the light is bright they produce more food than the coral needs so the unnecessary zoax get expelled. Now that said there are 3 types of zoax that produce at different rates in different spectrums and give different colours. Long story short, give the coral time to get some colour back, it will most likely be brown, and when the coral turns brown and healthy start giving it more light so it can get it's other colours back. It might take awhile. Good random flow is the most important. Now all that said, I have had several acros bleach and I just left them with no light changes and they eventually came back to full colour. Now that I said all that jibberish I would just leave it and it will probably come back fine. I see there is colour at the bottom so it should be ok. The best advise I can give is don't listen to me, I'm no expert.
