It looks like this inside a "fancy" glass mixing chamber.Has anyone ever tryed this?
I agree, it's probably DI mixed resin. If you want soft water do it the right way, get an RO unit - much cheaper in the long run as well.Looks like a knock off ADA Softenizer. Uses a Ion Exchange resin probably similar to a DI filter that would be on an RO setup. ADA might be able to give you more info on it as it looks the same.
