It is a shame that the PB discouraged you. You have a nice set up with IntelliCenter, latest Pentair VS pump, good size cartridge filter. Plan to add a IntelliChlor 20 SWCG and you will have a perfect setup, be able to control everything via your phone app.When we designed the pool, our designer steered us away from SWG. I'm not against it, it just sounded from him and some of the reddit forums like snake oil. But looking around here, seems like lots of the folks are SWG.
