I have very high phosphates - I don't test these myself (yet) but got water tested in 3 different pool stores and all turned out 4000 (which I understand is the maximum their program prints - but my level is actually higher). New pool owner, first season with the pool (opened in May), I have no idea why they are so high ...
1) Do I trust the pool stores tests or order and wait to get my own?
2) Do I treat or not ? (I read in the pool school and my understanding is that over 1000 I kind of should ?)
