    High CC

    Hi All,

    I have high high CC (2.0). I have a 20ft x 40ft inground - 30,000 gal I think. Any suggestions? Do I need to shock?

    TIA, Steve

    Welcome!

    How's the pool look? Clear? Cloudy? Green? Solid enough to walk across?

    Did you just pull the cover off before testing?

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.

    Re: High CC

    I'm using a Taylor K-2006

    This morning's readings:

    Ph 7.5

    TA 130

    FC 3.6
    CC 2.0

    CYA 80

    CH 90

    Water is clear. No algae at this point. FC seems tough to keep up lately - I have feeder wide open.

    Thanks for all of the replies!

    Short answer: yes, you need to perform the shock process. That CC is too high. For that matter, so is your CYA level and you're making it worse if you're using a puck feeder!

    You will be seeing algae soon if you don't get on it fast! Nip it in the bud!

    Re: High CC

    How do I get the CYA down? Change out water? If so, how much?
    Liquid Shock or Granular?

    When you say "you're making it worse if you're using a puck feeder" -- Are chlorine feeders bad? What should I be using?

    The only way to lower CYA realistically is by draining and refilling. Tap water has no CYA, so the math is pretty easy.

    Liquid shock or plain Chlorox bleach (or store brand equivalent - check the strength %) is what you need.

    Re: High CC

    I read "How to Chlorinate Your Pool". Is this a good plan?

    I'm going to drain some water (to the return), and refill.
    Use liquid shock (have to figure out how much).
    Will test everything again afterwards.

    Going forward I will turn down the puck feeder and use a maintenance regimen of liquid chlorine (need to figure out how much).

    If CYA doesn't go down enough, I'll repeat the drain and refill thing again.

    Does that sound like the right thing to do?
