I have a Frog and only recently learned (from here) about the unfortunate side effect of increasing CYA. I'm using only the chlorine cartridge, not the mineral.
If I keep it on a fairly low setting (say 1), can anyone give me a rough idea of how long it takes to start having a signficant effect on on CYA? For example, could it increase it from 50 to 57 in a single week? What if it were on a higher setting?
I'm wondering if I might have misread the CYA test in my K-2006. (Judging exactly when I can no longer see the black dot is a bit iffy for me.)
