pH Level Of My Pool
The pH level of my Intex pool (15 feet diameter) is very low and I have put in 2 boxes (in total 2 lbs) of Arm & Hammer Baking Soda into the pool. The PH level is not going up. The pool is about 3,600 gallon of water.
How many boxes of baking soda should I use to raise it from 6.8 to 7.6-7.8?
Thanks for your question Ada
As a general rule for the pH level of your pool it takes 40oz. (2 1/2 lbs) to raise a 20,000 gallon pool's pH 0.1ppm.
If you don't have a Taylor Reagent K-2005 or 2006 test kit I would encourage you to get one.
It takes a little getting used to but it's worth it because it will give you the most accurate reading.
Your pool is 3600 gallons and you say you're getting a pH reading of 6.8 and want to raise it to the correct level of 7.6 - 7.8. Using the above formula you would probably need 10oz. of sodium bicarb to raise the pH level 0.1ppm. To raise the pH to 7.6 - 7.8 you would use 70 oz. or 4lbs. of bicarb.
You can get a bucket filled 1/2 way with pool water and add the bicarb. Stir it with a stick then walk it around the perimeter of the pool (starting in the deep end) with the filter running. After the water has a chance to completely circulate through the filter, about 1 - 1 1/2 hours, check the pH again and make another adjustment if needed.

Start off slowly and work your way up when adding chemicals. You can always add more but it's a bit more difficult to take them out.
