New pool owner in a week. Took back the Frog System and decided to go with BBB. Thanks for all of the info.
My question is this--If CYA stabilizes the Chlorine, why is more needed as more CYA is in the pool? Meaning--why does that chlorine become "unavailable" (my translation--as more CYA=more Cholrine needed to maintain)? And if it is unavailable, what good is it?
Hope this makes sense.
