Just had my water tested at the local pool store. "Jr." wasn't interested in any of my numbers but the Phosphates!!!! I, on the other hand, just wanted to get some stabilizer. I figured since I was going there I'd take a water sample just to see. These are the results:

FC = 0
TC = 5? (he put an arrow pointing down after that?)
pH = 7.2
Alk = 80
CH = 190
CYA = 0
TDS = 450
phosphates = .25

The other thing he tried to "sell" me was calcium hardness. This amazed me because he never once asked me what size my pool was, or the material (it's vinyl).

I know I need to shock and get the CYA up. Do I need to be concerned with the phosphates and the Dissolved solids???? What the heck is that anyway??
