I have been transitioning my daily maintenance to my 13 year old son as he wanted to do more chores in order to increase his allowance. As he came in the back door this evening, I noticed he was carrying an acid jug instead of bleach. I learned of course that he had just poured 70 oz into the pool because he wasn't paying attention.
From PoolMath I am estimating this will lower my pH to about 6.2. It says that I should add 397 oz of Borax to raise the pH back to 7.6. There are some caveats on PoolMath however about pH changes being estimates, so I will need to let the water circulate and check in the morning.
So - any thoughts on what I should do to get this fixed? I added 25lbs of Boric acid a couple weeks ago, so my Borates are currently at about 40ppm. I'm worried about increasing the Borates too much and also what this will do to my Alkalinity which currently is about 100.
Should I go get some washing soda or soda ash instead? Any thoughts on the most cost-effective place to get these if that's the case?
