    Default What CYA level?

    According to Ben...

    _Stabilizer_____Min FC____Max FC___Shock FC
    _______ 0________1________3__________10
    _10 -__20________2________5__________12
    _30 -__50________3________6__________15
    _60 -__90________5_______10_________ 20
    100 - 200________8_______15__________ 25

    All Units in PPM

    I plan to switch to the 3B regimen. Question is what CYA level? Pool is in full sun 8~10Hrs/day in upstate, NY (temps range from high 60s to mid 80s in season). What are the pros/cons of low/high CYA?
