Just wondering what the consensus is on SWG runtimes and reducing PH rise. I've read enough on this forum to know that the operation of a SWG inevitably means PH rise and reducing runtime (and elevated CYA) is the goal. My question... is it the chlorine output setting or the actual runtime that contributes most the the PH rise. In simple terms, supposing I can keep my water adequately filtered and chlorinated in 8 hours/day on output setting 50%, would I be better off running my chlorine output on 50% for 8 hours or 16 hours on 25% to keep the PH in check? For the sake of this argument, I'm not caring about electricity costs.
BTW - the examples above are hypothetical to keep it simple. In my smallish pool I've managed to get everything working good in the cooler weather running the pump for 6 hours a day on the SWG's lowest setting which is approx. 10% chlorine output. Every now and then I bump it up to level 2 if the FC has dropped a bit. In hotter weather I need to run it higher, but I assume my PB over-specced my SWG to allow for this (thanks Phil)... all good considering he was still the best package out of all the quotes I got.
