What’s the deal with all the concern about phosphate? It seems people who use pool stores are always being told to reduce them. Is phosphate even a concern? When did it become a thing to treat for them? How do you really know they are there? I don’t even know if I have phosphates in my water. Why would they be there? Do I even care? A by product of some chemical or organic reaction? A pic of my pool water…..cause I like posts with pics.
