I have been a pool owner for 2 summers. I inherited a pool when I moved in. The person I bought from used EZ pool. I use it last year just because I was new. This year I ended up with terrible staining. I used Absorbic Acid and it took it away only to return a couple weeks later. I did the AA again, and it did not remove the staining. Now I can't seem to get my CL up. I added bleach and it did raise to 2 last night, but then it dropped overnight. (I also use a Trichlor 3 in tab inline feeder). Now today it was 0.8. Does it just take a little time to get all the AA out so the CL can stabilize? I am afraid to use shock to precitpate stains out. I am tired of the pool store info already, they really don't seem to know what is going on.
