We are new pool owners this year, and after a few issues, I have finally got our water looking great. My test numbers are finally looking good (still working on TA, but much lower). After an acid cleaning of my salt cell and keeping my CSI slightly negative, my chlorine issues have gone away. During all of this, my PB noted that my phosphate levels are very high and they may not be able to warranty my SWG if I do not get them down. After all I have read here, I understand that phosphates probably did not contribute to my cell scaling (it was high CSI), and I really do not have to worry about them. But for warranty purposes, it looks like I might have to.
So, I bought some professional strength phosphate remover and have been dosing for the past couple of weeks (cleaning the filter in between). The test I bought only reads up to 1000ppb, so I really do not know how high they are (or were). I have gone to 4 different pool stores to see where my level actually is, but they all just reported them as +1000ppb as well. So I have been dosing at the 5000pbb directions hoping that would be enough. I plan on adding my 4th dose today. Could they really be that high? I'm just wondering if anyone else has experience with phosphate removal or any advice they could give. Thanks.
