    Need Help on Steps

    Hello all,

    I've been using the BBB method for about a week. Last weekend I drained about 75% of my water to lower CYA and I shocked for days to resolve my disappearing chlorine problem. Right now things are good and my chlorine levels are getting down to an appropriate level. I tested my water and have the following results:

    CYA: 80
    pH: 7.8
    TA: 150

    I was going to work on the TA next by adding muriatic acid and aerating per the Pool School, however I wanted your input as to if I should actually drain some of my water again to lower CYA to 40-60 before continuing on? I live in Arizona and my pool receives direct sunlight from about 9 am until about 5 pm.

    Thanks in advance for your help.

    I recommend doing a little more water replacement, but not all the way down to 40-50. In Arizona with full sun on the pool all day, CYA from 50 to 60 is a better range.
