    A switching or variable-voltage system (also known as a "wavemaker") is commonly used in reef aquaria to more closely simulate the movement of ocean water. [ 1 ] Water circulation is vital to proper biological filtration of most saltwater aquaria (particularly those using the Berlin Method ), and is useful in freshwater aquaria for allowing ...

    en.wikipedia.org/wiki/Calcium_reactor

    A feed pump takes aquarium water into the reactor, controlling the volume of water exchange. This is important because a high rate of water flow into the reactor can reduce its efficiency, thus resulting in underproduction and a waste of CO 2. Some reactors siphon water into the input of the reactor's re-circulation pump.

    en.wikipedia.org/wiki/Aquarium_filter

    Canister filters were initially designed to filter drinking water, under low pressure. Canister filters for aquariums [17] use high water pressure, from a properly powered pump, to force water through the dense filter media. A pump can draw water from an under-gravel filter, and run it into a canister for double filtration.
