Tony, thanks for the response. It is appreciated.

They way I was looking at things, in a pool without SWG, there is no correlation between chlorination and filter run times. But with an SWG, there must be, since the SWG will be generating chlorine ONLY if there is water flow (isn't that the function of the flow switch -- to ensure that water is flowing through the system otherwise gases may build up in the SWG cell?)

I don't get the significance of the 100 minute cycle you mentioned. (Just me perhaps). BTW, I think the last part of your example (minutes 200-240), there will only be 20 minutes (50% of 40 minutes) of SWG "on-time". Bottomline is this -- if the SWG is set to 50%, then it will only be "on" 50% of the time that water is flowing (filtering) in the system. In doing some more reading on SWGs (the Aquarite in particular), its spec sheet says it will generate up to 1.45 pounds of chlorine per day. That would be @24hours filtering/pumping time. At 8 hours per day (my schedule), one-third of that amount of chlorine would be produced if I set the switch @100%. So the question is -- will 0.48 pounds of generated chlorine be enough to sanitize the pool?

Using the bleach calculator from this site MIGHT be useful in answering this question. So, using bleachcalc, I plugged-in my relevant numbers: 30,000 gallon pool, 6 PPM desired PPM target, 100% bleach strength for generated chlorine (would this be correct?). The result says I need to add 2 cups, 7 ounces to the pool. I don't know how to equate liquid chlorine volume with generated chlorine's "weight".

Am I making a valid comparison here?

Maybe someone who is familiar with that calculator can tell me if
