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.

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.

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

Do you have a swcg?
Are you using tablets to chlorinate your pool?
Post a full set of test results for us.

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.
