    CYA were high

    Hello pool and spa people.............Drained half of our pool water as the cya's were 95-100 .
    Refilled pool ...(we have a well on our property) as is alot of people in middle Tn are in a pre drought or drought condition.
    First readings after a 12 hr filter cycle are as follows

    Ok I need 3 quarts of 6% bleach and the pool calculator is stating some Calcium H? should I bother with it as I am between TFP recomendations
    Thanks man and have a Happy and Safe 4th of JULY.... .................. .......................

    **** our pool is above ground 13500 gals and a sand & De combo fiter.
    13500 gallon 24x4 round above ground... for my kids and mom.Trying the BBB method
    250 gal Dream Maker hot tub ...switch from the Baquacrap to the BBB method
    I use the hot tub almost daily due to muscle and bone soreness and pain.

    What kind of pool do you have? A vinyl liner pool doesn't need any added calcium, but plaster/pebble and fiberglass pools do.

    You certainly need some chlorine. Check your CC level tomorrow. If it hasn't gone down to 0.5 or lower by tomorrow you will need to shock the pool.
