A liquid dispensing system is provided for automated dispensing of a plurality of liquid reagents into a recreational body of water. The liquid dispensing system includes a cartridge apparatus defining a cavity, and a cartridge front wall. A plurality of liquid reagent containers are included, each containing a respective liquid reagent and each being disposed in the cavity in a manner permitting access to each respective liquid reagent through the front wall. A docking assembly is provided having a dock manifold device, and is releasably coupled to the cartridge apparatus between a first condition and a second condition. In a first condition, the cartridge apparatus can be removably coupled to the docking assembly, while in the second condition, the cartridge apparatus is lockably mounted to the docking assembly in a manner permitting fluid communication through the cartridge front wall from the respective reagent container to respective fluid passages of the manifold device. The dispensing system further includes a dosing engine having a valve manifold device that includes a plurality of intake ports and a dispensing port. The intake ports are fluidly coupled to the respective dock manifold fluid passages, via connection tubes, and the dispensing port is configured to deliver the liquid reagents to the body of water. The dosing engine further includes a valve assembly fluidly coupled to the valve manifold device to manipulate the flow distribution between the respective intake ports and the dispensing port. The respective liquid reagents can then be selectively dispensed to the recreational body of water through the dispensing port.
