FC = 7.5 (is this level unsafe?)
All other levels acceptable.
1. I had my water tested at a pool store bc I wanted to know the metals and phosphates were 1000. Of course, they were trying to sell my PhosFree but I didn't bite. Should I add an algaecide?
2.Pool stores said nitrates were 15. Should I treat this? They couldn't do iron and copper bc they were out of the strips.
3. In the next week I think that I am going to do an absorbic acid treatment so I need to bring my TC down anyway but if I was not going to do the test, would you suggest turning off my SWG for a day to bring it down?
