21 foot round above ground linered pool with a 1 HP Hayard pump and a Hayward Perflex DE Filter.
I went to Leslie's and bought a pool opening kit. Spent over $100 there a added all the chemicals the way the instructions said to.
What did it get me? A whole lot of nothing! Here are my results using the Taylor K-2006 test kit.
FC = 0
CYA = 70 to 80
TA = 0
Ph = Under 7 (it turned yellow and the closest indicator on the k-2006 is orangish at 7.0 so I don't know how to get an exact number)
The starter kit had 4 bags of chlorine which apparently only raised CYA and not FC. Also Algae Control and some other cr@p.
The pool is clean, except for a little bit of dirt in the crevices at the bottom.
Water looks nice and clear. If I hadn't tested it, I wouldn't have known that it needed anything.
