I am very confused here and maybe I am not using the Hanna Phosphate test kit incorrectly! maybe others had run into this situation. I have been having some strange issues, like mushrooms turning white in my reef tank. I did what everyone would probably do is to test all water parameters. I know that my red sea max has always run at high phosphates, but corals seem to do well as it is mainly a softy / LPS tank. I used my hanna phosphate test kit and got a 2.25 reading (ppm), so I retested and got the same reading. I was ready to start dosing slowly with Phosban-L but decided to use the Salifert test kit and to my surprise the results were .25! I don't get it and don't know what is correct here ... I will say that I had some bad experience with my hanna alk test and was always way off so don't even use anymore.
If .25 is correct, then I would not try to lower obviously and that would be an acceptable range for me. But if it is truly more then 2 then perhaps that's why some mushrooms not doing too good. I also don't want to begin dosing something like Phosban-L as it is very potent and can have a negative impact on everything else in the tank.
