I have done a lot of reading on this subject and am still a little confused.
My FC has gone from a 5 to 3.5 over the course of a week. The latest readings are as follows.
This morning at 10AM
FC 3.5, system was not generating at time of test due to 50% setting
CYA 40-45, still not sure how accurate my readings have been
Wtr 83 deg
% out 50%
So what is the correct chart or numbers to use. i read one article where is says Most saltwater chlorine generator (SWG) pools appear to prevent algae at a minimum FC level of 4.5% of the CYA level as compared with the roughly 7.5% of the CYA level shown in the "Min FC" column for manually dosed pools.
Having said that then 4.5% of my CYA level of 45= min FC of 2 which I know is probably too low.
My Aqua rite manual says to maintain a CYA of 60-80 with 80 the best and FC of 1-3.
Just want to make sure I am understanding what ratio to use for salt system.
