I went to the pool store for the first time this year to purchase supplies and just for the fun of it, I took a water sample. They now test for phosphate, a new thing at my local store. Mine is 3162; I was advised to add phosphate remover. I read an older post on this forum from a few years ago that said not to worry about phosphates. Wondering if this is still your recommendation? My water and pool are beautiful with no problems. It was open all winter. I greatly appreciate your advice.
