man my phosphates went up to .28!!!! Everything looked like crap and I was checking and I was overfeeding like usual but I forgot to turn on my skimmer... changed the gfo and skimmer and did a 20g water change and it's down to .03 but I think I shocked many corals for doing this... T_T my zoas are very unhappy and my center piece acro colony is bleaching... T_T
