    My CC iS ZERO

    Please forgive me if I missed this, I really did try to find the answer first...

    After a very long SLAM to convert from using tablets to the BBB method, for the first time today, my CC is 0.0. Don't I wants to between .2 and .5 or is zero okay?

    Ph is 7.5
    Fc is 7.2
    Cc is 0 (I did it twice)
    Alkne is 90 (only came down 10 after adding muriatic acid to lower ph)
    Calcium 190
    Cya 60
    22,000 gallon pool---In ground--Oval--16x32---Vinyl liner -----Cartridge Pentair filter
    Pump= Century HSQ 165 (installed 2016) ---New liner in 2014 when we bought, orig. build date unknown
    Test kit Taylor K-2006---Manual vacuum---Bottom drain not in use, odd plumbing setup

    A CC of 0 is ideal. Also note there is no need for 0.2ppm resolution. Use 10ml of water for the FAS-DPD test so each drop is 0.5ppm

    A reading of 0 for combined chlorine is awesome. That's what we all strive for. Way to go, I think the lowest reading for CC for me has been 0.2 which is still awesome, but I think in my 3 years of being a cpo I have only achieved a 0 reading once. Congratulations
