So here's a very newbie question. If CYA is a stabilizer it should maintain whatever the corresponding FC level is according to the CYA/chlorine chart, right? Why then the need to add anymore bleach at all?
I know that this is a sill question but I just wanna make sure my thinking is correct. Even though CYA is a stabilizer the FC level will still diminish, just not as quickly, right? So daily bleach is still needed.
