I’m a newbie to posting on here.
I have an 21ft above ground pool and the liner is stained, tanish color that does not scrub off. I did the test and cane up with an organic stain. Th CYA was 200 due to using tabs but we have stopped that and drained the water halfway down. My numbers are-
Alk 80
PH 7.2
Ch 13
CYA 115
Is there anything I can add to the water to clean the stain up? I added a photo to show the stain, it’s all over except the small area around the steps. I have never had this problem before!
