I have 0 nitrates but I do have phosphates. Per a salifert test kit between .25 and 0. While that is high, why are my coral so unhappy. I have a biopellet reactor on week 4. I know that biopellets don't take care of a ton of phosphates but I do have gfo. It's in a bag but is tumbled with a mj1200. Not the most efficient way but still better than nothing. I should turn my reactor into a gfo reactor or just be patient? I will get phosphates test with real equipment when I can make it to that lfs.
