Due to the way the SWG works, I think (my own opinion) that it is better to run longer but lower so that the pool is more constantly chlorinated. SWGs work low and slow (low level of chlorine added, so more time is needed). You can vary the % of output, but what you are really doing is varying the amount of time during the ON cycle that CL is being generated, not the amount of CL generated (at least with the Aquarite). So, by running longer but at a lower %, the CL generation gets spread out, so (maybe) there is less of a roller coaster effect on FC in the pool. That is one of the reasons for using a 2 speed pump, it reduces the cost of running the pump so I can run it longer. (Hope this makes sense).
Yes, makes sense. Thanks!
