I am in the market for a new saltwater generator and am looking for input from other saltwater system owners. I currently have a Polaris AutoClear for which the cell has reach its end of life (I think). So, I have to decide if I want to replace the cell for a discontinued system or replace the entire system. My fear is that if I replace the cell that something else might go out and I'll have to replace the system anyway after purchasing the cell or that the cell might not even be the problem (all indications are that it is the problem). Does anyone have any feedback they can offer on the CircuPool RJ series systems or comparable systems? Also my pool is an 18x36 grecian 3.5-8.5 deep. I need to know where I can get the total water volume. I haave found sources that state it is from 23,000-33,000 gals. My guess is that it is somewhere between.
