From a sample taken in the morning a few hours after the salt generator was shut off. The system was run for 12 consecutive hours overnight.
FC - 0.6
CC - 0.4
PH - 7.6
TA - 110
CH - 800
CYA - 40-50
I have the generation level set to max (100). I will be checking the chlorine levels again later today to compare.
I have a small amount of visible algae on the walls at the waterline. Aside from that, the pool is clear. I have been adding about 1/2 gallon of 10% liquid chlorine twice a week to supplement the salt system. If I don't do this, the pool will begin to green in about 2-3 weeks.
The salt system is an AquaRite and is about 3 years old. The salt cell was replaced last year. It initially made a higher level of chlorine (maybe a month?) but seems to have dropped down to the same levels above. I've been battling this problem from day one it seems, and have all but lost faith in SWG in general. The pool builder hasn't been much help beyond replacing the cell. They have their own store and seem to be more focused on selling me some snake oil to fix my problem (surprise!!). I get a different answer from every employee I talk to. The same holds true for other pool stores.
Is it possible that even with CC of 0.4 I have a chlorine demand high enough to keep the salt system from really doing a good job? Maybe my CYA level isn't high enough? Also, I have a waterfall feature, which I run constantly when the filter/SWG is on. Could this be contributing?
Any help is appreciated!
