my tank just hit 6 months old last week and has gone sps dominant but I do still have a lot of LPS in the low lighting doing good but not great. Over the last couple weeks according to my Hanna ulr and salifert I am only barely detecting phosphate at all. Salifert is always dead 0 and the ulr is giving me a reading of 0 or 1 depending on the day so about .003. I'd like to keep my phosphate levels around .02-.03. I am running a dual reactor from BRS with gfo and carbon. Should I ditch the gfo and carbon reactor? Maybe use less? I'm already using maybe 2/3 of the recommended amount. Nitrates stay around 1-5 like I want since I feed the fish pretty well everyday. I do find it a little weird tho because I def get some algae on the sand here and there and thought that was a product of phosphate. I think this also may be why my LPS don't seem as happy as well so would definitely like to get the number up and prefer not to dose another thing if possible. Any help and advice is appreciated guys. Thanks
