Just completed a new pool and it was filled with water 3 weeks ago. Having been testing (Taylor K-2006) and following BBB for about a week. Plaster company came back out this week and repaired plaster - lowering pool water level about 8 inches and refilling. Below are my test results
23,000 IG gunite pool, standard plaster
pH 8, was 7.2 before plaster was repaired
CYA 28? a little less than 30
I am decreasing pH again and will work to increase CYA (40?) and CH (260?). Let me know your thoughts and advice on these results and target given the new pool. Thanks in advance for your help.
