    FC high and climbing

    Folks,

    I am running my pump on high 24/7 right now for aeration (reducing TA for borates). My TA has hit my target value of 70 and I have demonstrated the ability to raise PH by 0.5 in 24 hours with my homemade aerator. Here is my problem, I have a SWCG and it is cranking out chlorine! Latest test results:

    TC: 13 (was 11.5, SWCG set to 45%)
    CC: 0
    PH: 7.0 (added MA tonight)
    TA: 70
    CH: 20
    CYA: 40
    Salt: 3500 panel

    There has been no bather load whatsoever and the pool is clean. Should I simply shut off my SWCG for the time being? If so, how?

    TIA

    Okay ... I think I just had a duh moment .... reduced cell to 15% for tonight. I will recheck in the AM. No swimmers, no sun, and it has been cold ... all equals no FC usage ...

    You might even shut the cell off for a while and let the FC come down on its own.

    Tested this AM. Aeration is working but FC still rising. I am going to turn off the cell for today.
