A little more than a week ago I bought a friends entire 25 gallon livestock, I put it all in my 55 tank right after cleaning both my scrubber screens and I got a nice little phyto bloom (less than 6" visibility). I assume it was caused by a N and or P spike from dumping all the live sand into my sump while my algae scrubbers were weak from cleaning. I put in a aquaclear filter with some floss and activated charcoal to help strain a bit of the phyto out of the water, I was hoping to get it clear enough to organze stuff without squishing anything.
When i put frogspawn and the green star polyps in the tank, they looked amazing, they were doing GREAT. As the tank got to be about 12" of visibility I took out the aquaclear (and charcoal) and topped off the tank with a gallon of kalk into the sump (2 tsp powder and 90ml vinegar). The next day it seemed that only a couple polyps in the GSP were open and the frogspawn was only partially open as well. The day after that the GSP was totally closed and the frogspawn was very close, now it has been 3 days and the water is looking good but both of them are shut of as tight as can be. About a day ago I put some charcoal back in the tank, thinking there might be some coral warfare going on with everything getting moved, but there was no visible result.
Throughout this whole time I have been messing around with my uberbright LED fixture, trying to get everything adjusted to it without burning the crap out of them, it is possible the frogspawn got a little sunburnt, or is not happy with the light changes, however the GSP is in like 5 spots all over my tank, in high light areas, medium light areas, and in shade, since every colony is closed as tight as can be, I assume it is not the light affecting the GSP, although it is not impossible.
So now it has been 3 days and I havent seen a peep from either one. Any idea what might have caused this, and what I could do to fix it?
