A P.S. to Sean,

I seem to recall that the typical settings people are using with the salt chlorine generators is that they are on less than 50% of the time. Is it possible to have them on 100% of the time (when the pump is running), but operating at a much lower power level? Don't the lower power levels operate efficiently even at lower levels of CYA? If that is the case, then the simplest thing for owners of SWG to do would simply be to use the lowest power setting and increase their % on-time accordingly.

Of course, running at 100% means you have no leeway for the system to increase this if more chlorine is needed (due to increased chlorine demand), but if your system would instead just vary the power as needed (instead of the time) then this approach might work. What do you think?
