Hi all! A couple days ago I did a sizeable water change on my tank to help remove Cyanobacteria, and all was normal in the tank was normal for a day, but yesterday evening I noticed what looked like snow on my montipora?
It was not there in the morning and nothing has been introduced to the tank for several weeks. Nitrates are near zero and nitrites are at zero, phosphates are low and I maintain dKH around 10.
Any idea what this is or how I could fix it?
