I have studied a lot about switching to SWG. I have a 27' round, AGP w/17,150 gal. I have been looking at the Aqua Trol since I can plug my twistlock pump right in to the panel. I don't really want the extra expense of having to wire the pump to the panel then the panel into my outlet box. But.... is the Aqua Trol, rated for pools upto 18k gallon, sufficient to keep up? I live in the western Chicago suburbs, we can get some real hot, sunny days and lots of rain in the spring. I never really have a large bather load 2-3 people at a time max. What I don't want is to have to add a manual dose of chlorine now and then because the SWG can't keep up.
Also, I like to keep FC around 3ppm. With a SWG, if the FC were to drop to say, .5 (because of heat, rain, bathers....)will a SWG produce enough chlorine fast enough to boost the level of FC before it drops to 0 requiring a shock?
