Trying to figure my FC goal:
SWG 70 for CYA
recommendation according to Pool School at http://www.troublefreepool.com/content/128-chlorine-cya-chart-slam-shock
CYA (Stabilizer) 70
Minimum FC 3
Target FC 5
However, if I use Pool Math, set for SWG, Plaster, it recommends:
CYA (Stabilizer) 70
Minimum FC 3
Lower Target FC 8
Upper Target FC 10
Which target should I be using? I had always been using the Pool School Target of 5, but noticed PoolMath is recommending 8-10. Has something changed?
