I have recently replaced the SWCG in my way over-chlorinated (50+ ppm) new to me pool and fired the PB. Yesterday the FC was at 11 so I'm finally nearing the time where I'll be using the SWCG full time for chlorine. Problem is, I have no idea where to set it. The PB was using bleach because the old cell and controller were shot when we moved in. I understand that chlorination is a factor of SWCG percentage and SWCG/Pump runtime. Pump Runtime X %SWCG Opeation = Minutes of Chlorination
How does this plan sound?
The plan is to set it to 30% once FC drops to about 7 or 8 based on a FAS-DPD test and see what happens daily. Hopefully it will slowly drift to 5 or so and then I'll tweak it from there to maintain 5 based on the FC/CYA chart.
