Water circulation is important to a healthy closed aquatic environment. Without it, the system can become unstable, leading to the growth of algae and other unhealthy substances. This is true for marine and freshwater environments.

The most efficient way to move the water is by using a pump and/or powerhead. Fortunately, hobbyists can choose the right pump and powerhead for their aquarium from the full range of Rio Aqua Pumps/Powerheads, which are designed to work in a variety of aquatic environments.

All Rio products offer high performance at an affordable price.

They use the finest in modern technology and materials to create the best pumps and powerheads in the industry. The ceramic shaft and durable high-impact plastic make the pump reliable and long lasting. Magnetic rotor technology offers low maintenance and high reliability and because it does not use oil, it cannot contaminate your aquarium environment.

Although the Rio delivers a high flow rate with tremendous pressure capability, it is quiet to operate. The fully submersible Rio Aqua Pumps can be used to operate wet-dry and under-gravel filters, venturi protein skimmers, fluidized bed filters and any other equipment that requires a pumped water supply.

Rio Aqua pumps can also be used as return pumps for sump tanks below the aquarium or within the aquarium itself, wherever circulation is required, in both fresh and salt water.

The Rio400 pumps up to 400L / 144G per hour. These pumps make great recirculation pumps or powerheads. Please note that although this pump can be used as a return pump for a wet-dry or Berlin system, Aquariumpros.com does not recommend using this pump for this purpose. Please see our line of heavy-duty submersible pumps, which are designed for use as filter return pumps.

Fully submersible, titanium-shaft, Rio pumps offer a variety of uses - circulate water, drain/fill your tank, even power a waterfall! Their tremendous pressure makes them excellent for skimmers. Includes: mounting bracket, suction cups, venturi attachment, intake strainer, and U/G adapter.
