So I have a RO/DI system that the filters were bad in and I just upgraded to a new system with new filters. The question I have is, the two tanks I have (125gal with 75gal sump and a 90gal with a 25gal sump) have been running for about 6 months with my TDS at 180. Can I do water changes with the new system with a TDS of zero or do I do a complete water change. Also after I get this all turned around , will I notice a difference in the tanks?
