Abstract
A chemical controller device for delaying the distribution of chlorinating chemicals into a swimming pool is disclosed. The chemical controller includes a floating dispenser with an inlet port and an outlet port. The floating dispenser contains the swimming pool chlorinating chemicals. A plug of a suitable chemical which dissolves in the pool water sealably blocks the outlet port and prevent contact between the chlorinating chemicals and the pool water. The chemical plug dissolves in the pool water over a period of time and then starts the chlorination process. The length of the chemical plug determines the number of days before the plug dissolves and thus when chlorination of the pool will commence.
