    Where is my baking soda going?

    I got my test kit on Thursday. I saw that my pH was low at 7.2 (I'd been taking my water tests to Leslie's before this and all this season they told me it was high > 8.0) So I added 2lbs of baking soda per the pool math calculator and let the pump run for a few hous. The next day I retested and the pH had barely budged, so I added another 2lbs. This morning, same thing, barely budged, so I added another 2lbs. Any thoughts as to where all that baking soda is going? Is there some kind of pH buffering going on? Or am I using the wrong chemical? This was my last bucket of Leslie's Alkalinity up, Sodium Bicarbonate

    Ummm..baking soda is used to raise your TA. What does your test kit show that to be?

    umph... my TA is 90, up from 70 when I tested it a couple days ago... wrong chemical... I was trying to raise my pH. I saw that pH is related to alkalinity in ABCs of Pool Chemistry, and I had this bucket of something called Alkalinity Up, so ... yeah... umph

    oops! Not worries, it will come down with addition of MA.

    The TA controls how quickly the pH rises. Generally speaking, the higher the TA, the quicker the pH will rise....

    Re: Where is my baking soda going?

    If your ph was too low, you might need a higher TA. If your cya is high and you're using tabs, you might need a higher TA.

    How are you chlorinating?

    What is your CYA?
