Evolution Aqua Tempest Filter

Evolution Aqua Tempest Filter





Innovative Polisher For Ponds


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. 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.   


Using Evolution Aqua’s K+Media as the filter media, particles down to one micron can be filtered. Not only that, K+Media is the result of extensive research and development, moulded with minerals for faster maturation times.


Evolution Aqua filter media has been independently tested by IFTS (Institut de la Filtration et des Techniques Séparatives).




How it works

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.


Easy to clean

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.




Tempest filters can be installed on a variety of set-ups. For best results the optimum flow rate is 5,000 LPH / 1,100 GPH / 1,320 US GPH. Maximum flow rate is 7,500 LPH / 1,650 GPH / 1,980 US GPH.

On larger systems that require a higher flow rate, multiple Tempest filters can be installed in a modular system.




K+Media is designed and manufactured by Evolution Aqua. This advanced media, with its innovative design and class leading surface area provides enhanced biological and mechanical filtration. As Evolution Aqua extrude the K+Media, minerals and enzymes are added to the raw material. 


The result of this process, unique to Evolution Aqua, is a filtration media that not only outperforms most of its competitors due to its large protected surface area, but also answers the problem of how to speed up the time taken to mature your filter.
