    I am burning through the chlorine

    I put roughly a half gallon in a day. It is not in use, is that normal?

    FC 3
    CC 0
    CYA 30
    TA 120
    PH between 7.8 and 8

    Seeing grey dusty looking sediment on the bottom. We have been running the vacuum, almost every day, rained 2 inches yesterday. No swimmers yet pool is up to 75 degrees.
    Still clear.

    Not using chlorine tablets, just liquid 10%.
    Filter is cleaned almost daily as well.
    I have a 24ft round pool. 52in deep. 14k gallons. It has a sand filter. It is a chlorine pool that we got March, 2016. Above ground!

    Re: I am burning through the chlorine

    You don't have a baseline so how can you say you're burning through chlorine?

    With a CyA of 30, a FC of 3 looks about right.

    I could be wrong. I have been before.

    Re: I am burning through the chlorine

    A half gallon of bleach in a 7000 gallon pool is a lot, not so in a 30000 gallon one.

    It's best to look at how many ppm of FC you are adding daily (chlorine demand). 2-4ppm a day is normal. If you are not using the pool, but it is in the sun all day, 2-3ppm would be about right.

    I like a CYA around 45ppm and raise my CL-to around 6-7ppm. It works for me but I live in IL.

    I didn't see it was being added every day but rather just that it was added hence my confusion on a base line.

    Re: I am burning through the chlorine

    So, how many ppm of FC are you adding each day?

    Remember that when it comes to sand filters, a slightly dirty one works better. You should not be back washing daily unless your filter pressure is rising 20-25% daily too.

    In your sized pool, 18 ounces of 10% LC will raise your FC by 1ppm. So you're only adding at most 3.5ppm daily. Sun UV can easily burn that much up daily too.
