I have a ~15,000 gallon pool (pebbletec) that I began maintaining myself last fall. We recently had a pretty heavy calcium scale line (12-year old pool) blasted off and I was hoping the draining required to do the work would help with CYA, but it wasn't really enough to make a dent.
Chlorine tabs have been used exclusively, but I am planning to make the switch to liquid. CYA has basically stayed at 90 since I started doing my own testing. Just did fresh testing and also realized my CH was higher than I realized, likely because I was not initially getting to the final blue color before stopping the drops/counting.
Based on these numbers, should I consider doing a partial drain and refill to gear up for the summer? While on the high end, it seems like these are manageable and that the CYA may come down over time if I stop using the pucks.
