my pool is crystal clear. I tested today using AquaChem 6 way test strips. total ch was 1 free ch was between 0-1 ph between 7.2-7.8 total alk about 120 stabilizer was about 75. I also tested salt level with Aquachek strips and is running between 4670-5080. I have ABG 15' round 1hp hayward pump my salt generator has operated since day1 but the chlorine total and free concern me. my swg runs 24 7 have been running pump about 8 hours a day. My manual for swg says to look for bubbles coming from swg to insure that it is working. What kind of bubbles am I looking for? little like air bubbles or bigger bubbles? We cleaned the cell today but it looked fine even before we cleaned it. If it isn't the swg do I need to run my pump all the time or do i need to shock it? Thanks for any help that you can give.
