BTDG:

Relax: there are situations where higher CYA levels are called for. aylad runs her pool high because there's SO much loss due to sun and biologics she needs more stabilization. So she compensates by running a higher residual FC level.

But SWGs need higher CYA levels and lower FC levels. I'm not sure of all the chemistry, but years of watching the SWG people has me convinced.
