## Abstract

A water treatment device which is attached to the feed hose immediately above or behind deep water pool cleaner. Includes a cylindrical body that is slotted on either side within which a water treatment substance is housed. An outer cylindrical sleeve that rotates over the main cylindrical body is used to regulate the flow of water over the water treatment substance such that quiescent conditions prevail inside the holder. The device is equipped with buoyant end caps as to minimize impedance of pool cleaner to which is it attached. Provides distribution of dissolved water treatment substance throughout the entire body of water from the bottom up.

## Claims

### Claim 1

A dispensing apparatus for dispensing chemicals to purify the water in a swimming pool, said apparatus comprising:
a semi-transparent, plastic, main body slotted on opposing sides to allow water to flow and contact an encased water purification material; said body having an "L"-shaped slot at one end and a permanent cap fitted on an opposite end, said cap having an air chamber defined by a permanent disc to provide buoyancy; and
a semi-transparent, plastic, cylindrically shaped control tube with oblong slots, which fits over said main body to control the flow of water through the main body slots by rotating the control tube over the main body; and
a removable cap fitted with a pin to engage said "L"-shaped slot, said removable cap having an air chamber defined by a permanent disc to provide buoyancy; and
plastic straps for attachment of said apparatus to a hose.
