Weve had this pool going on 3 years. Its a 14K gallon plaster pool with a Polaris SWG. It has never really worked correctly and doesn't appear to have ever been a popular system. We had the system replumbed last year to replace some broken valves and add in a heater. This year we want to add another SWG to the system and wanted to get some input as to what are some good options. Price is a concern, but so is ease of use and control.
