An inflatable massage pool comprises a pool body defining an inflatable cavity and a water receiving cavity. A water inlet assembly, located in the inflatable cavity, is configured to provide one of a filtered water flow or a massage water flow to the water receiving cavity. The water inlet assembly includes a water inlet pipe and a water flow guiding device. The water inlet pipe has a water inlet passage in fluid communication with the water flow guiding device for delivering one of the filtered water flow or the massage water flow to the water receiving cavity. The water inlet passage and the water flow guiding device delivers the massage water flow and the filtered water flow into the water receiving cavity in different paths or the same path, thereby reducing welding points on a pool wall, lowering the manufacturing cost, and reducing the difficulty in pipeline arrangement.

A control box of a massage pool is provided and includes: a filtering water pump unit, including a filtering pump body, a filtering water inlet pipe connected between the massage pool and the filtering pump body, and a filtering output pipe. The control box further includes a massage pump unit, including a massage pump body, a massage inlet pipe connected between the massage pool and the massage pump body, and a massage output pipe. The control box further includes a water outlet pipe configured to output water to the massage pool, and a three-way connecting pipe fitting. The three-way connecting pipe fitting includes: a first branch pipe having a distal end connected to the filtering output pipe, a second branch pipe having a distal end connected to the massage output pipe, and a third branch pipe having a distal end connected to the water outlet pipe At least one valve is configured to alternately open and close a first flow path from the filtering output pipe through the first branch pipe.

A method for treating water in a spa or a hot tub includes, for example, suspending a water treatment dispenser from an upper end of a filter cartridge disposed in a skimmer of the spa or the hot tub. The dispenser includes a water treatment material. A supply of water is passed from the spa or the hot tub into the skimmer and through the filter cartridge so that the dispenser suspended in the filtered water in the filter cartridge is operable to dispense the water treatment material from the dispenser, and a supply of treated filtered water from the filter cartridge is returned to the spa or the hot tub. A cover, for example, may be employed when the dispenser is not used.
