After a year with my new pool, I'm now toying with the idea of switching to salt. All of my pool equipment is Pentair with the exception of my Intermatic mechanical timer (T21004R). I don't use the timer in the Intermatic, it's really only being used as a power distribution panel since my IntelliFlow VS pump has a built in timer. With that said, I'm trying to find the most cost effective way to switch to salt. It's my understanding that if I want to add a Pentair SWG I will also have to invest in a power supply as well as an automation system. After some quick math, adding all of that would cost anywhere from $1500-$2000. Is there a more cost effective system out there, maybe one that is self contained with its own power and control system built-in? Also, I'm thinking the yellow area in the picture below would be a good place to add the SWG, thoughts?
