Until recently I ran the pump for 2x3hr sessions per day for total 6hrs per day, the SWG was set at 50%.
Consistently getting FC results 6.8 to 7. I wanted to drop this to 5 so I set a new regime at 1x 3 and 1x2 for a total 5 hrs per day with SWG set at 100% expecting that dropping 1 hour pump time per day and increasing SWG from 50% to 100% would pretty much cancel each other out. However within 2 days the FC dropped from 7 to 4.8, my question is......does pump time have a far greater impact on chlorine product than output setting? Perhaps something like FC=0.8PT + 0.2OP where PT = pump time and OP=SWG output?
