An apparatus for controlled dissolution and dispensing of a water treatment chemical including a chemical chamber disposed above a humidity chamber through which water flows at a controlled rate. A metering device controls the migration of moisture into the chemical chamber for dissolution of the chemical and for feeding of the chemical into the water passing through the humidity chamber. The water/chemical solution exiting from the humidity chamber enters into a settling chamber and is then directed to the water supply.
