Circulation pumps

Eheim - Circulation Pumps for Your Aquarium!

Corals in saltwater aquariums depend on solid water flow: since they can't swim to their food, the food has to come to them. But freshwater aquariums can also be equipped with circulation pumps for various purposes. Canister filters can filter large volumes of water, but an even, powerful flow throughout the entire water column is best achieved with circulation pumps. For these cases, EHEIM has come up with a powerful and flexible solution. Thanks to its integrated ball joint, the streamON+ can be swiveled by 180°, and it can be mounted both vertically and horizontally. Suitable for smaller aquariums as well as large tanks of up to 500 liters.
For flow that comes even closer to a natural aquarium, EHEIM offers the Streamcontrol flow simulator. It lets you imitate changing water currents like those in rivers or on coral reefs. It has two sockets and can control several pumps at the same time. This way, every aquarium can be supplied individually with suitable flow.
