I got my water tested at a different pool supply place than normal (I won't mention the national chain), I didn't have time to drive the 40 minutes to the company who installed my pool who I trust.... The test said my TA was 57 ppm and to add 25 lbs of ph stabilizer. They also told me to add 3 lbs of pH lower first which I think sounds about right....I have and IG liner about 27,000 gallons with a SWCG. This is my first season with the pool I had it put in last fall. I read some posts and am second guessing the suggestion of 25 lbs. I did add about half the amount suggested in 4 applications over 5 hours. I also bumped up the SWCG to 90% for the day to bring up my FC. I will lower it back down to 30% tomorrow. Thanks for the help! This looks like a great forum.
