Anybody have experience with this brand of phosphate test? It is what they used at my lfs to test my water. I know salifert and Hanna and red sea are among the best but who has experience with red sea it's self and how accurate? My readings are .12 and I know that's kind of high but I do not have a sps tank. Only a duncan some zoas a pulsing Xenia and a hammer and I know they don't like a "dirty" tank but not as low of levels as sps. So around where do I need to bring my phosphate down so all corals can thrive. Just bought some chemi pure elite with gfo to help remove phosphate. Thanks guys
