    Pool numbers

    I am new to the BBB method and have some numbers I am questioning.
    FC 10
    CC 0
    TC 10
    Ph 7.5
    T/A 80
    CH 320
    Cya 80
    Salt 3100
    Temp 85

    I have a 8600 gal pool spa with a spa spillover in extreme South Florida gunite I beleive. It is between 2 houses and doesn't actually get too much sun.
    1.5hp hayward pump for pool and spa
    2.5hp hayward for spa only
    90 ft^2 hayward cartiridge
    80000btu jandy heatpump
    autopilot nano SWG(new)
    I am still working on the SWG setting to get FC down but I turn it down and wait a few days to see what happens.

    Your numbers look about perfect...FC of 10 is just a bit high but fine given 6-9ppm is the range for your CYA level

    Great job!

    Once you finish dialing down the SWG to get to the recommended [s:3jqhakmi]3 to 5[/s:3jqhakmi] 4 to 6 FC, you'll be golden

    Edited to correct FC levels to correspond w/CYA of 80. Yes, what dman said

    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.

    Re: Pool numbers

    With CYA at 80, your acceptable FC range is quite wide. 3 would a little low for my taste. 4 is your minimum while 6ppm is your target. That said even though this is a SWG pool...the Non-swg levels of 6-9 are also still very acceptable. 6ppm is justyour sweet spot

    Many consider anything below shock level safe for swimming. With CYA at 80 your shock level is roughly 30ppm.
