I recently upgraded to the RODI from Marine Depot - a 100 gpd value unit. It’s been working fine. Our well water has about 450 tds going in and has been 0 coming out. I’m running water today and tested it and it’s at 16 tds. I go through DI resin very quickly but at least 1/3 of it is still blue. Any ideas what’s going on? I do have resin so I could change it but it’s not exhausted yet. I think I’ve only been using this unit for a month or two on a 32g tank so it hasn’t gotten much use.
