thanks for the tips. would a blackout period over for a weekend be harmful to corals?

When I did it, I only had SPS. I saw a bit of colour loss, but everything colored right back up after a few days. The GHA on the other hand seemed to draw back a bit for the first day, I think, but then it just came back worse then before. Try it though, what worked for me may not work for you and vice versa.

This is one of my threads documenting my war on hair.

Trevor, I have done the blackout a couple times. Never hurt corals none. I was using it to rid Cyano. Was allways doing 2 days no lights, but not covering tank. Cyano back in a week. Last time, 2 days covered with thick towel, and 3rd day, no lights. Then, 6 rd actinic, 3 hrs daylight on 4th day, 5th, resume light schedual. And my sand was pearly white, cyano and hair was gone. I only had a small patch of hair, never even noticed it was gone till I got that Xenia from you. LOL Which, BTW is thriving nicely.

I have acctually read of people who do 2-3 days blackout once a month to keep thinks white and fresh looking, with no ill effects. i mean, on the real reaf, they have extremly cloudy periods too, dont they?

I should mention that the colors in my SPS came back brighter and stronger then before my blackout attempt. Only the GHA responded unfavorably for me.
