Today I got a pH reading of approx. 7.9/8. Per the Taylor K2006 kit, I believe I am suppose to add approx. 5.5-7 lbs of dry acid into my 18K gallon vinyl pool. I purchased some from Leslies and before carefully reading the instructions, I added about 3.5 lbs of Dry Acid at once. The instructions say to not add more than 20 oz per 10K gallon pool, that means I've added approx. 24 oz more than I should have. Will this have any harmful affects to my pool?? Also, I've must of added about 20 lbs of this stuff this summer trying to battle a high pH level, is there any side effects to this?
