    Do I have a bad SWG cell or SWG?

    All,
    I have been having problems over the last month keeping my fc at or around 5ppm.
    I shocked the pool last week in respose to my similar post to this as some suggested I may be fighting an alge bloom.

    I currently have my (oversized) SWG to 70% while running my pump ~8 hrs. a day and continue to lose FC.

    Overnight FC Loss Test resulted in an FC loss of .5
    Here is a set of numbers taken this morning:

    FC 2 (Down from 2.5 last night)
    CC 0
    pH 7.5
    TA 90
    CYA 75-78

    Curious if there is anything else I can check BEFORE I call the manufacturer and make myself soud stupid.

    Thanks

    Your OCLT would tell me you are not fighting an organics problem in your water, and that sunlight is consuming your chlorine. Is your CYA really as high as you think it is? The Pool Calculator would put your target at 4 ppm. I would bump up the % and watch it for a few days. Is your water clear?

    Water is clear.
    CYA test should be pretty close. (I was careful and thorough)

    I will bump up again and see.

    After a simple test, manufacturer told me I had a bad LED controller. No matter how far I turned up the SWG it only got to 10%.
    By the way, the customer service at Circupool gets and A+.
    Part will be here Friday and I am told it is an easy install.
