Jack's Magic Purple Stuff 1 qt (2 Pack) - Pool & Spa Maintenance

I got this stuff when we got our new pool a year and a half ago and have been using it to mostly keep my salt cell from getting calcium buildup and blowing out white flakes into the pool. We have a fibreglass pool and our calcium levels have to be a bit higher according to the manufacturer. It works well.What I didn’t realise until recently is that it contains phosphates and I have been battling with high phosphate levels ( I know, there is no consensus on whether to remove phosphates, every pool professional has different opinions) for the last year, spending money on phosphate removal products while unknowingly adding phosphates. I stopped using this a month ago and my phosphate levels are way down.I just bought the Bioguard Salt scapes Scale defender and I’m going to see how that works as it supposedly does not contain phosphates according to a local rep.
