    Baking Soda Question

    Hi, how much baking soda do I add to a 10,000 gallon above ground pool to raise the alkinility? It's at 50 now. The boxes I bought don't have any info.
    thanks.

    If you will visit http://www.thepoolcalculator.com, you can calculate the numbers by populating the appropriate fields.

    Checking the numbers myself, it looks like 47 ounces by weight will raise it from 50 to 70.

    Re: Baking Soda Question

    Before you go raising it, tell us more about why you feel you need to raise it?

    Is your pH jumping around?
    Do you have a swcg?
    Are you using tablets to chlorinate your pool?

    You can stop SLAMing your pool when you pass the OCLT (You lose 1ppm or less FC overnight, & You have .5ppm CC's or less) & your water is clear.

    If you are using trichlor tablets, I suggest raising TA to around 150. You can use the Pool Calculator to figure out how much baking soda you need to add to do that.
