We opened our 39,000 gal vinyl liner pol last summer. After setting all winter it's a dark green mess and u cant see 6" into the water. I know the bottom is covered in leaves since last Fall. I tested the water with the cheap hth brand test strips and readings as followed:
FC: 0 Ph: 6.4 TA: 120 TH: 200 CYA: 0
which do I adjust first? Do I Shock the pool (using Cal-Hypo) and then add Cyanuric Acid and Soda Ash or do I fix the Ph before shocking and see if the CYA levels come up on their own after shocking it, as I'm pretty sure I remember reading Cal-Hypo raises CYA levels. Thanks!
