If one has iron issues, wind born dirt and iron, and pollen, but maintains a pH of 7.3, and sufficient sequestrant ppms, would it be better to maintain chlorine on the high side if the CyA, in a non-saltwater pool, is 50 ppm? Or even in a saltwater pool at a a CyA of 80 ppm.
The reason for asking this question is that at higher CL levels of say 8 or 7, in this theoretical example, the HOCL level would be higher than say at 5. I am lead to understand, higher HOCL levels oxidize considerably faster than the reserve OCL-, which oxidize at a far slower rate. Would this then oxidize pollutants entering the pool more efficiently than at the lower chlorine level of 5, for pools with wind born dirt and iron, and pollen issues? Thereby taking oxidized metals, and other pollutants, to the filter at a rate this faster acting HOCL can keep up with, thereby reducing potential staining issues; allowing these oxidized pollutants to be eventual removed during backwashing.
Or would the reverse be true, or would it make no difference?
If higher levels were better, would the higher reserve of OCL- also help to maintain control of contamination? As OCL- can keep the HOCL level at a higher constant, in that % HOCl (vs. Total Free Chlorine) does not change between FC 8 7, and 6, but at 5, and 4 ppm, drops from 1% to 0.9.
I realize that the consumption of chlorine might be increased somewhat, if the level is kept higher. That would be OK if overall stain control could be improved upon.
Thank you to those that might help
