Preparing to add NaCl this weekend. Have the TFP Kit, CYA is over 100, If I dilute current pool water by 50% then it goes to approx 60. Currently dumping water. The pool was previously chlorinated with tablets. Question, how did CYA build-up so high in the pool? Did years of tablet use and stabilizer addition create this scenario, or does it happen by some other mechanism? Tempted to drop the pool volume to around 40% prior to refill to allow for a target CYA of about 50? Thoughts?
Thank you...
