I just tested my pool and my TA is 190. Is that to high for a vinyl pool, 20,000 gallons. No other problems. Pool is crystal clear. I recently added absorbic acid to try to get rid of stains on my step, which didn't work. I was wondering if this would raise my TA. Do I need to worry about the 190 or is is OK? By, the way I just started using BBB this year and I am thrilled. This is the best my pool has ever looked. Thanks for all the help
