My tank has been running for over a year, my phosphate always been 0.16-0.22 corals doing great tested today, and its 0.36ppm. I noticed that calcification slowed down, my alk went up from 9.6 to 9.9 and 450 calcium to 480-490. Mag also. How dangerous is the situation? I would lose corals overnight?
