I am closing my pool today. My numbers.
PH: 7.8 - 8.0 not dark enough for 8.2
CYA: 10 just a guess cause I could not see the dot at 20 and barely with tube filled all the way.
I way gonna bring to slam level at 10 CYA. Then add polyquat 60. Let run for any hour or so and start draining to blow out lines. In the past before TFP method when I opened I had to add baking soda. So I am banking on PH going low over winter. I live in Louisville,Ky so our winters are not terrible like you up north folks... I do have a mesh cover so I get all the drain through from the sky. Does this sounds ok to close?
