I am in trouble. Had a thriving tank up until I did an ICP test and noticed phosphates were out of control at 2.1ppm - ended up dropping it to 0.3ppm with phosguard over the span of about 50 days, and some type of process in dropping the phosphates seems to be killing my LPS. Tank is a year and a half old and here are parameters.
My only theory is potentially the alkalinity plummeted due to either the Phosguard or dropping phos. Tank normally runs at 8.7 dkh and the phosguard treatment seemed to have dropped it to 7.9 dkh. After a small water change it went back up to 8.3 dkh last night. Could this swinging be what is causing my issues or is it maybe something else entirely? At a loss trying to figure this out.
