I recently went through some major ups and downs in my tank. It had been stable for more than a year & I put in a new rock that leeched phosphates into my water. I started to lose corals which is why I discovered the problem. Once I removed it, the phosphates dropped, very rapidly from .25 to .07 (in 1 day) and I guess this stressed my corals even more.
Anyway, no to my question. During the process I lost several corals over night, total white bleach out. Then several started to STN. I fragged them & put them on plugs but now every couple of days a new frag or coral is starting to STN.
Is STN caused by something in the water I can remove?
All my params are back to normal & have been stable for more than a week.
