Abstract: An environmental control device for aquariums, ponds, or terrariums includes: a casing; an environmental control device, adapted to control an environmental condition of the aquarium, pond, or terrarium; and an NFC communication device configured to communicate with an external unit. The external unit is configured to exchange data with the NFC communication device so as to monitor and/or control an operating parameter of the environmental control device or an operating condition of the environmental control device or environmental condition of the aquarium, pond or terrarium.

Abstract: A metering unit for the controlled supply of a substance inside an aquarium tank comprises a containment box and a dosimetric pump which is actuated by an electric motor, both being associated with the containment box. The containment box has at least a first connection element and at least a second connection element which is suitable for being connected to a corresponding first connection element of an additional similar metering unit.

Abstract: A fluid-dynamic pump which is suitable for circulating water in an aquarium includes a rotary device, an electric motor configured to move the rotary device, a pump body which houses a printed circuit board which that controls the electric motor and a temperature sensor that detects the temperature of the water of the aquarium. The temperature sensor is positioned on the pump body.

Abstract: A skimmer (1) for aquariums comprises a base (10) and a container (20) which is provided with at least two lateral connectors (21, 22) which comprise a main connector (22) and an auxiliary connector (21). The skimmer further comprises a cup (30), in which the foam is collected. The base comprises at least four openings, a first opening (11) and a second opening (12) opening inside the container (20) and being connected to a third opening (13) and a fourth opening (14), respectively, so that the skimmer can operate at least in two different configurations: a first single-pump configuration and a second double-pump configuration.
