A filter well mountable dispenser holder securable within a hot tub filter well with the dispenser holder supporting replaceable dispersant containing dispensing cartridges positionable within a circulating flow of water through the filter well to thereby release dispersants therefrom without preventing the circulating flow of water from passing through the filter media proximate the dispensing cartridges.

The present invention provides a method for comprehensive monitoring, analysis and maintenance of water and equipment in swimming pools said method implemented by one or more processing devices operatively coupled to a non-transitory storage device, on which are stored modules of instruction code that when executed cause the one or more processing devices to perform: —acquiring continuous data from acoustic sensors; —propagating said data to an online remote server, —applying machine learning algorithms at the online remote server configured to incorporate the acquired data and provide recommendations and control parameters, and —providing an online interface to access said recommendations for at least one of: pool owners, pool servicemen, pool maintenance companies, pool vendors and pool retail dealers, wherein applying said machine learning algorithms comprising applying an acoustic model trained to learn the behavior of said data acquired from said acoustic sensors and to identify at least one of a device failure, location of a failure, type of failure, and the mutual effect between/among devices/instruments undergoing failures and other devices/instruments in said pool system.

Systems and methods for providing network connectivity and remote monitoring, optimization, and control of pool/spa equipment are provided. “Internet-of-Things” (IoT) functionality is provided for pool and spa equipment in a flexible and cost-effective manner. Network connectivity and remote monitoring/control of pool and spa equipment is provided by various components such as a network communication and local control subsystem installed in pool/spa equipment, and other components. Also disclosed are various control processes (“pool logic”) which can be embodied as software code installed in any of the various embodiments of the present disclosure.

Chlorinators with multiple spaced gas traps and flow sensors are detailed. The sensors also may be protected, at least somewhat, from contact with scale build ups by interposition of a mechanical barrier. Ramps or other geometric restrictions may be used to increase water flow to some or all of the gas traps. Additionally, the chlorinator housing may be configured so as to route, or focus, gases toward a small-sized, high point thereof.

A publicly accessible urban beach entertainment complex is disclosed, with a man-made tropical, pristine-clear lagoon as the centerpiece of the complex. The lagoon includes a surf feature and surrounding the lagoon are entertainment, educational, sports, and commercial facilities. The complex has a controlled public access and provides the look and feel of a tropical beach with clear waters and sandy beaches. In addition a method for efficiently utilizing facilities and land that are vacant, underutilized, have limited uses, or that are contiguous to or nearby recreational, educational, sports, or commercial venues is disclosed. The method providing a publicly accessible urban beach entertainment complex with a centerpiece man-made tropical-style pristine-clear lagoon having a surf feature. The method allows for generating revenue and increasing efficiency by pairing vacant sites, underutilized sites, limited use land, or sites that are contiguous to entertainment, educational, sports, and/or commercial venues with urban beach entertainment complexes. The complex preferably has a controlled public access, thereby allowing entrance upon payment of a fee.

A float feeder device helps make a Chlorine Generator Unit easier to install, and prevents a pool filter pump from drawing air and losing its prime while the suction created by the pump draws concentrated chlorinated water. The device regulates the flow of concentrated chlorinated water from a chlorine generator to water to be treated. The device includes: a float housing and a float assembly that moves up and down within the housing. The float assembly has a float with an elongated stopper member that projects downward and has a conical stopper end. An output port allows concentrated chlorinated water out from the bottom end of the housing. A rubber O-ring at the output port permits flow of concentrated chlorinated water only through the rubber O-ring, and receives the conical stopper end to form a fluid-tight and air-tight seal whenever the conical stopper end is seated on the rubber O-ring.

A method for treating water in a spa or hot tub includes, for example, supporting one or more water treatment dispensers from a supporting structure in an upper end of a filter cartridge disposed in a skimmer of the spa or the hot tub. A first dispenser includes a first water treatment material and the second dispenser includes a second different water treatment material. A supply of water is passed from the spa or hot tub into the skimmer and through the filter cartridge so that the first dispenser is disposed in the filtered water in the filter cartridge to dispense the first and/or the second water treatment materials from the first and/or dispensers, and a supply of treated filtered water from the filter cartridge to the spa or hot tub. One or more caps, for example, may be employed when the first and/or the second dispenser is not used.

A floating dispenser having an external float or an internal float for supporting a cartridge or cartridges for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser having cartridges rotationally positionable with respect to one another to control the rate of dispensing while the dispenser floats in an upright condition with the floating dispenser changing its flotation orientation in response to consumption of the dispersant or dispersants in the a cartridge to thereby provide a visual alert to replace a spent cartridge with a fresh cartridge. In addition, the inventions described herein permit changing the dispensing nature of the system from a multiple dispensing system to a single dispensing system without changing the floating characteristics of the floating dispensers through replacement of a dispersant in one of the cartridges with an inert or ballast material that has no effect on the water characteristics.
