    using too much chlorine

    I just pulled my pool cover off a few weeks ago. It just started warming up in California here. I have been putting a gallon and a half chlorine daily. Whats up with that? PH is fine. I have not checked others yet. The water is crystal clear

    Yup, need to know the CYA. What is the liquid chlorine strength?

    What does thev water look like?

    What test kit you using?

    Re: using too much chlorine

    I see you listed the TF-100 testkit. How old are the reagents in that kit? Post up a full set of current test results from that kit.

    FC
    CC
    TA
    CH
    CYA
    Water Temp

    An OCLT may be warranted - Perform the Overnight FC Loss Test (OCLT)

    Re: using too much chlorine

    Beyond what the others have posted, is that chlorine left over from last year? Even if you just bought it from a store, it could still be last years and is essentially expensive salt water.

    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: using too much chlorine

    TC 5.5
    TA 80
    Calcium Hardness It comes out light pink- does that count at red?
    (Calcium = 150) ( how do yopu know it has copper? Directions say if pool contains copper add 2 drops R012 before
    adding R011L)
    CYA - it's always clear. It never gets cloudy. It goes all the way too top and I can clearly see black dot. Did it twice.
    Ph - 7.8
    My water is crystal clear.

    ps the neighbor cut down trees that now give me sun till 7 pm every day. Before sun was blocked by 1:30.
    The kit is two year old.

    Re: using too much chlorine

    2 years is starting to push the life expectancy of some of the reagents in that kit. I would recommend ordering some refills.

    Sound like you have near 0 CYA. So that means you can lose 50% of your FC in a hour of noon sun ... and likely lose it all every day.

    Raise that up to 30-50ppm (depending on your location ... add it to your profile please )

    Re: using too much chlorine

    I'll give it a shot. Thank you. When I do pool calculations it says to add 326 ounces of calcium chlorate for my calcium hardness. Does that sound right??
    Seems like alot.

    Re: using too much chlorine

    That seems like a reasonable amount of calcium . I would just Target 250 PPM
