I just got the TF 100 test kit and tested my pool. The results are as follows,
Calcium Hardness 550
Total Alkalinity 220
PH 8.2, I keep lowering the PH with dry acid but it keeps rising back up.
According to pool math I must drain pool by 1/3 and add 78 oz of dry acid.
Is there any other way to adjust pool parameters without draining?
