Alot more than 32 ounces of acid was added to a 15000 gallon pool to get from 8.2 pH (what you showed earlier) to the sub 7.2 level you show there.ph looks close after the tech added a quart of acid.
Yes that’s too much! Add 3-5ppm , pour it slowly infront of a return & brush the area.Thanks again - it says it would raise FC by 21. I’m guessing that’s way over the target of 3?
Just to clarify what Kim said... 15 minutes is good for liquid chemical additions.What’s the time frame for checking levels once I’ve added chemicals?
Liquid is more expensive, and you don’t have to dissolve it. Other then that none at all.Is there any benefit to dry vs. liquid CYA?
