My wife is not crazy about using the BBB method. She put something in front of me that reads as follows:
"If chlorine concentrations are above recommended levels (5.0 ppm for super-chlorination, or 10.0 ppm for shock) for long periods of time, gradual bleaching for most liners will occur"
Is there any validity to this? My levels spike up to about 7 ppm daily and reduce down to 4 ppm daily based on my CYA. My CYA is 40-50 (around 50) with minimum of 4 and target of 6. Because of daily loss, the 2 ppm difference is not sustainable. The pool will go through 3-4 ppm per day.
Any thoughts? Thank you.
