What is the best way to recharge the intank, but removable, water softener?
From the Insanely Long Water FAQ: another_jim wrote:This is the small softener sold along with the Silvia that fits on the intake hose end. The softeners sold with other machines look identical, so this may be a generic product. I was told to recharge mine weekly with a few tablespoons of pure salt in a highball glass. The test result is based on this procedure. This softener also does not completely eliminate hardness. In my case, it reduces hardness from 150 mg/l to about 50 mg/l. The performance is about equal to a new Brita jug filter. Weekly recharging keeps it at this level. At this level of softening, my water still generates scale, but at about half the rate of unsoftened water. The softening creates close to zero LI water at coffee brewing temperatures, albeit with higher alkalinity than hardness. The combination of a new Brita and hose end did reduce the water to a 20 mg/l nonscaling level.
