    Need to add some CYA

    Our CYA is probably less than 10. The previous owner left a bucket of trichlor 3" tabs (that are at least circa summer 2005) and I put some in the auto feeder to try to help raise the cya.

    I am trying to avoid adding the 'good stuff' until the backwashing is less.

    The tabs were stored in our basement, sealed well and stink. So they probably have some 'good' left?

    I check FC/pH every day.

    Assuming the tabs still have some power, about how many of those will it take to get my CYA to around 20 to 30?

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    It takes quite a bit of trichlor to get to a reasonable CYA level. 15 of the 7 oz tablets will get you to a CYA level of 24.
