    How to do a big rise in TA

    ive just completed a Jacks copper removal program and I've been slowly bringing the water back in balance. Here are today's measurements:

    TC 3
    pH 7.3
    TA 20
    Borates 40
    CH 400 (same as source)
    Temp 68
    CA 40

    Pool math suggests 9# of baking soda to get me to 60. That's a lot! Any suggestions on adding that much? Small batches of 1-2# with checks? All at once? Can I expect some temporary cloudiness?

    Once TA is ins check, I'll work on CA.

    Thanks

    Anytime you are adding that much, its always recommended to add in 3 doses with 8 hours in between. You can then check between. Cloudiness shouldn't occur if you do it slowly, but your Ch is considered high, so maybe go even slower.

    I should mention, it's me that recommends splitting up dosing, not TFP.

    I doubt it will be an issue. Some years ago I added somewhere around 20 lbs without incident.

    Caution is the best help, however.

    I had absolutely no cloudiness and it dissolved very quickly and I got valid test results within an hour

    I just put another 2# in. I'm at 40.

    I love it when a plan comes together! Thanks for the quick help!

    Re: How to do a big rise in TA

    When I was needing to add TA, I bought 13lb bags of it at Sam's. I'd use a 16 oz plastic cup and broadcast 3 cups into the pool at a time. Test it again and add more as needed. It too dissolved very quickly.

    CSI is not that low now. If it were me, I would leave TA at 40 and maybe raise PH a little with some borax or aeration. With high CH fill water (and high TA too?), it won't be long before you wish you had a low TA. Just speaking from my own experience.

    Re: How to do a big rise in TA

    I agree with keeping it low. I keep it at 50-60 because I dose acid regularly to combat pH drift from SWG and that has a TA erosion effect. No higher than 60 for me.

    Everything's lookin great. TA at 50 and I'm about to swap out acid in doser with bleach for the winter. SWG won't be effective after this week's cold weather. And with SWG off, pH tends to hang tight.
