I have read several comments from "aylad" that say he runs his pool at high CYA levels (and presumably high chlorine as well). What's the advantage? I'm currently running at FC=13.0, CYA=80. Ph=7.6, TA=100, CH=200. The forum has been invaluable in helping me with my chemistry. I guess I'm trying to decide if I should drain partially to reduce CYA or let it ride.
