My CL consumption has now increased from less than 0.5ppm/day (winter) to around 2ppm/day thanks to the summer weather. Does the CL consumption rate behave in a linear fashion or does it drop faster starting from higher levels? Like would it drop faster from 20 to 10ppm than it would from 10 to 0ppm? Or would it take roughly the same # of days dropping the same 10ppm amount? Thought I read about this last year, but can't find the thread now.
This is all assuming I have no algae bloom or anything serious.. just basic weekly maintenance. Pool is always balanced and clear thanks to BBB. Also my CYA is about 70.
