    Abstract: A water level detection system in a pool, spa, fountain or water feature, the water level detection system being provided with a tap line coupled to a plumbing line on a suction or supply side of a filtration system and admitting water from the pool, spa, fountain or water feature such that the change in level of the water in the tap line corresponds to a change in level of the water in the pool, spa, fountain or water feature. A sensing module has at least one sensor for detecting the height of a column of water or the pressure of a column of air in the water tap line. A controller is coupled to the sensing module and adapted to collect the data from the sensors that detect changes in the level of the water level of the pool, spa, fountain or water feature, communicate the detection of such a change, and report such a change to initiate addition or removal of water from the pool, spa, fountain or water feature body of water to adjust the water level in the body of water to a set point.

    Abstract: A pH balancing solution dispenser having an upper body portion and a lower dispenser body portion. An interior support portion is provided with a dispensing grid and an at least one piercing mechanism thereon. A dispenser lid and an at least one dispensing mechanism are provided wherein a container of pH balancing solution is placed within the upper body portion and situated in communication with the piercing mechanism. The container is pierced and opened and the pH balancing solution flows from the container through the dispensing grid and is stored for distribution by the at least one dispensing mechanism. A unit controller can be provided to meter a dose of pH solution when instructed by the pH balancing solution dispenser to balance the pH of the body of water based on the estimation made by the unit controller using the measured operational time.

    Abstract: Some embodiments provide a motion control system controlling an image projected from an underwater projection system in a water feature, pool, or spa. The system includes a rotatable base and a mirror support member hingedly coupled to the rotatable base. A first motor is coupled to the rotatable base and is configured to rotate the mirror support member in a first plane. A second motor is coupled to the rotatable base and a fixed mount, wherein the second motor is configured to rotate the rotatable base relative to the fixed mount thereby rotating the mirror support member in a second plane.
