This may sound stupid, but bear with me here.......
I came to this site because I had a CYA over 400. I solved it with a drain, and am fine, but this question comes from all the reading I've done on this. Over and over, everyone says the only way to lower CYA is a drain. Yet, when someone has Ammonia in the pool, their FC and CYA go to zero, because of the Ammonia. So, could you force the pool to an Ammonia state, let it kill off the CYA, then SLAM to get your pool back to normal? I realize this will take a lot of Chlorine to kill off the Ammonia, but that may be more desirable than a drain for some people.
So, what causes a pool to turn to Ammonia, and can it be forced?
