Howdy,
When you say "brine type", I assume you refer to the regeneration of the cartridge?!
In general, the best way to soft water is reverse osmosis. Ion exchangers (such as those that are regenerated by brine solution) add other ions to the water (sodium & chloride), maintaining conductivity of the water constant. Part of softwater tanks is also conductivity, so I don't think it's a good way to go.
