So I have large cell amphidinium. I have had them for about 2 months. I have kept them kind of in check. Lost an sps and 2 fish which has been a bummer. I found out I had them and took to the forum to ask. Was told I needed to dose microbacter7 and hydrogen peroxide. So I did that yesterday. my Dino’s were covering about 30-40 percent of my sand bed yesterday and PO4 was .09. Today after dosing yesterday it’s bloomed to probably 80-90 percent. And my PO4 is now at .17 according to my Hanna checkers. Obviously I am going to stop dosing. I don’t want to do water changes. I have been using phosguard to try and keep my phosphates down but doesn’t seem to be working. Also my nitrates have held steady around 1-1.5 which is why I have this problem to begin with I think and know I need to raise. I do have neonitro as well. Just wondering what to do. What’s the best way to get phosphates down without water changes?
