    Welcome to TFP!!!

    If your CYA is 0, then you would lose all your FC to the sun in a few hours.

    What does the water look like now?

    Welcome grayham!

    According to your numbers it sounds like the Sun is getting the FC. Bring it on up to 40-50 and see how that does for you.

    Re: loosing chlorine fast

    Did you have CYA in the fall?
    Was this a new fresh fill?
    Did you test the CC?

    Re: loosing chlorine fast

    Hello Grayham! Kudos on doing your own tests with a proper test kit. I think we all see the same thing ... no CYA. It's like trying to keep coins in your pants pocket with a hole in it. Once you add some stabilizer in there as advised above, it will serve as sunscreen for your free chlorine (FC) and you'll see much better results. By the way ....... welcome to TFP!

    You can use either the granules or the liquid. The liquid is a bit quicker of course, but I think costs a little more. The granules have to be placed in a sock by your skimmer so it can be slowly dissolved and ingested into your skimmer.

    Re: loosing chlorine fast

    CYA granuales are by far less expensive than the liquid.

    Those are much better numbers than before. Although you may want to bring that PH down a bit to your recommended 7.5-7.8 range. Don't let the FC drop below 3. After a few more days, check the CYA again. You don't need to check that every day.
