Abstract
A liquid treatment apparatus or system having a liquid treatment medium bed which is regenerated by passing through it a solution formed by dissolving a solid in a liquid. An automatic control system initiates a regeneration cycle when necessary. Indicia are provided in association with the container containing the solid material such that an appropriate indicia will represent the amount of solid material in the container. By providing the control circuit with the indicia, the control circuit will record the amount of solid material remaining and initiate an alarm when the amount of solid material remaining is below a predetermined level.
