New to the forum and just beginning to digest this CYA-dependent FC dosage.
I have a couple of questions.
1. Does CYA affect the FC measurement in any way? Will the FC that is bound to CYA still be measured by pool testing kits? I am using Lamotte's ColorQ Pro7.
2. Since I am the manager of a small private pool (20-30 swimmers/day) I am somewhat reluctant to operate the pool at higher than 3 ppm FC levels (I currently have a CYA reading of 75 ppm). Although I understand that at the end of the day it is the CYA/FC ratio that determines the effect of chlorine on swimmers and garments, are there any official publications that I could use in order to convince common people that is is safe to swim in an 8 ppm FC pool?
