My CYA is high, I'm reading 88 ppm, and I know I need to drain the pool so I will by the end of the week. Yesterday, I added about 3 quarts of 12% chlorine in order to raise the level to 9 ppm according to the chlorine/CYA chart. This morning I read no chlorine in the pool. Here's my most recent readings. I used the K-2006 test kit, did it as conscientiously as possible, and it was my first attempt doing it myself (other than Chlorine and pH).
CYA 88 (opened pool 2nd week in may. read 10 ppm. using chlorine tabs and shock rose to 70 ppm in weeks. just got through turning green pool blue and developing algae again.)
I am being consumed by this pool. All of my energy is being poured into it. I feel like my back yard is a chemistry lab. All I want to do is enjoy it. Not happening.
How much liquid chlorine would you need to add to your 20k gal pool over a period of a week (7 days)?
