so i wanna keep some phosphates? or get rid of them all?test like 5 times honestly, I hate API kits lol but I would get some phosguard in a small bag, go with half the recommended amount and test again in 12 hours and then test again after another 12 hours. Phosgaurd exhaust pretty quickly but if you put too much it'll strip your tank.
