    Should I increase TA?

    Test Results:
    FC - 1.5
    CC - 0
    TC - 1.5
    TA - 60
    CH - 120
    CYA - 40
    pH - 7.2

    I am dumping some bleach in the pool when I finish writing this to bring it up to 6 ppm

    It appears that the recommended level of TA is 70-90+, 2.7kg Baking soda

    Yes, it would be good if you raised TA. How does your water look?

    My water is crystal clear (I'd like to keep it that way)

    Can I just dump all the Baking soda into the water? It will easily dissolve?

    Yes, you can just dump it in, but I prefer to premix it in a bucket and then pour that in.

    I added 2.5 kg, that's all I had left. According to the Pool Calculator that should bring it up to 79 TA. I'll have to go out and grab some more Baking Soda when I re-stock my bleach supply.

    For several years I have been adding Baking Soda through the skimmer with the basket in with no problems but then I have a sand filter.

    Baking soda is very forgiving of being added in a wide variety of ways. With some of the other chemicals it makes a much larger difference how you add them.

    Plug your numbers into Pool Calculator. See what CSI is. Then decide if you want to add more baking soda, if you even need more, and if there's anything else that needs adjusting.

    Re: Should I increase TA?

    This is off topic, but I don't think it deserves its own thread.

    I added my bleach and baking soda yesterday. Today I vacuumed the pool and OMG!!!! The water is sparkling. The heater has the water at 84 degrees and it was my first swim of the season today!

    I was admiring the water and I go thinking about shocking the pool. If I was to keep my water in balance as carefully as possible, will I ever need to shock the pool? Or is shocking something thats going to have to happen, but good pool care will decrease the number of times needed to shock each season?

    You can keep your pool balanced and not ever need to shock it. We have members (I used to be one ) that have never shocked their pools. Never needed to. I am sure some of them will be around to brag a little before too long!

    Re: Should I increase TA?

    We just put in the pool in at the end of last summer, so we don't have any landscaping yet and the grass is a bit of a mess. This is a shot I took standing on the diving rock.

    Thanks! Now that the pool is done I need to work on the rest of the landscaping.

    Re: Should I increase TA?

    The only reason I had to shock my pool recently is:
    1. I went out of town for a week
    2. The Liquidator scaled on me and stopped feeding FC
    3. My buddy watching the house has no idea how to run a pool.

    Since then I have:
    1. Solved the scaling problem with borates, which has also stabilized my pH and lowered my FC use
    2. Raised CYA to 40 to also help FC use

    As of now, I do not expect to ever need to shock my pool again! (I don't close my pool for winter, keep the water balanced year round)
