Dispensing systems
A non-dissolvable immersible dispensing puck in the shape of a dissolvable halogen puck when the dissolvable halogen puck is in an undissolved state with the non-dissolvable immersible dispensing puck physically interchangeable with a dissolvable halogen puck when placed in a dispenser for normally holding only a set of halogen pucks to enable a single dispersant dispenser to be converted to a dual dispersant dispenser without changing the structure of the single dispersant dispenser by placing a dispenser within a dispenser wherein only one of the dispensers may be provided with adjustable water ports.
1. A non-dissolvable immersible rigid dispensing puck comprising:
a rigid circular top member having multiple water ports therein;
a rigid circular bottom member having multiple water ports therein;
a rigid cylindrical sidewall having multiple water ports therein joining said side top member to side bottom member to form a closed rigid container having a dispersant compartment therein, said multiple water ports in said top member, said bottom member and said sidewall allowing water to flow in and out of said dispersant compartment; and
a dispersant comprising a granular source of metal ions located and retained in said dispersant compartment, and
a set of resilient strips on the rigid circular top member spaced around the periphery of the puck, each strip extending axially away from the rigid circular top member and having an inward facing lip for attaching the non-dissolvable immersible rigid dispensing puck to a halogen dispenser.
2. The non-dissolvable immersible rigid dispensing puck of claim 1 wherein the top member, the bottom member and the sidewall are fixedly joined to each other to form the non-dissolvable immersible rigid dispensing puck.
3. The non-dissolvable immersible rigid dispensing puck of claim 2 wherein a diameter of the non-dissolvable immersible rigid dispensing puck is about 3 inches.
4. The non-dissolvable immersible rigid dispensing puck of claim 1 wherein the granular source of metal ions comprises a silver ion source, a copper ion source, or a zinc ion source, the puck optionally further containing clarifiers, algaecides, algae stats, or aluminum sulfate.
5. The non-dissolvable immersible rigid dispensing puck of claim 4 wherein the multiple water ports comprise openings of a fixed size which are sufficiently large to permit water flow therethrough but sufficiently small to retain the granular source of metal ions within the dispersant compartment.
6. The non-dissolvable immersible rigid dispensing puck of claim 1 wherein the top member, the bottom member and the cylindrical side member comprise a non-dissolvable polymer plastic.
7. The non-dissolvable immersible rigid dispensing puck of claim 1 wherein the rigid circular top member, the rigid circular bottom member, and the rigid cylindrical sidewall form the closed rigid container as a rigid one-piece container having the dispersant compartment therein.
