I helped my neighbor through a SLAM a couple of years ago. I tried to talk her into using TFP but she declined and went back to pucks. She asked for my help again recently because, of course, she was fighting an algae outbreak...one she couldn't beat. Now, unfortunately, her CYA is up to 110 (at least that was my estimate using the CYA test.) She didn't want to change water out prior to doing the SLAM so I conducted it at the elevated CYA level. It took four days but there was no drop in the chlorine level last night and no CC so the SLAM is completed.
Other than having to conduct a SLAM at a high chlorine level, are there negative effects of living with a high CYA level? She will change out the water over time and she will be using TFP philosophy (with my help) so her CYA will be declining and no longer growing. She has purchased a TF-100 test kit and I will help her do her tests.
And, yes, she remembered when I told her she would be stuck with high CYA and fighting a continual battle with algae!
