Here are the latest facts:
FC is very high (>10).
Ph=8.2 and rising
foam/air bubbles are still present especially when running SWG
I have used over 40 gal of bleach in the past 2 weeks. At what point do I cut my losses and drain?

How do you determine the 15 level? Is there a test kit that measures that high? The level must be high because the color is orange instead of yellow in the test kit I have (the worthless test strips even indicate it is 10+).

I am beginning to think the foam may be air bubbles. My ph is rising. It was around 7.6 yesterday then 7.8 last night then 8.2 this morning. I think I read that aeration can raise the ph level. Do I need to add acid now to lower ph or just continue to filter? I have been running the SWG on and off to help with the chlorine levels but maybe I need to turn it off completely until the chlorine level holds. Will this amount of bleach cause the foam or air bubbles?

I am at my wit's end but I really appreciate your help
