Evolution Aqua Tempest Filter - Pond Filter and Water Polisher

Introducing the new Tempest from Evolution Aqua. The Tempest filter is an innovative polishing system for ponds that will help to deliver crystal clear, healthy water. Supplied with Evolution Aquas New K+ Media. Designed to be used in conjunction with any filtration system, the Tempest offers additional mechanical and biological filtration. The Tempest filter can also be used on quarantine systems or as a standalone filter on smaller ponds up to 5,000 Litres / 1,100 Gallons / 1,320 US Gallons. The Tempest filter is easy to install and is simple and quick to clean, by way of a unique, patent-pending, air syphon design. During the cleaning process, air is drawn into the filter as it empties which causes the water to agitate, effectively cleaning the K+Media. Water is pumped up through the Tempest filter. The K+Media moves to the top of the filter, becoming a mechanical barrier that traps debris as it flows through the system. Waste is trapped in the K+Media until the cleaning cycle dislodges it and it gets flushed away. With the pump turned off, slide valves closed, and waste valve open, air is drawn into the filter. As air and water mix inside the filter tube, the media starts to move chaotically, dislodging the trapped waste. Dirty water then exits the filter tube at the bottom via the waste line, leaving clean media.
