The Tempest filter is easy to install and is simple and quick to clean, by way of a unique, patented air syphon design(UK Patent No. GB2550495B).
During the cleaning process, air is drawn into the filter as it empties which causes the water to agitate, effectively cleaning the K+Media.
Independently Tested Filter 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.
The Tempest Filter can be cleaned in matter of minutes, by simply turning the pump off, closing slide valves and opening the waste valve tap.

Installing the Tempest Filter
There are a number of ways the Tempest Filter can be installed on your pond system. Below are some typical installation ideas.
PLEASE NOTE: The slide valves fitted to the Tempest Filter allow connection to 1½” pressure pipe. If installing the Tempest Filter using flexible hose you will need to fit a reducing sleeve (EA Code: M35-050) and a 1½” solvent weld stepped hosetail (EA Code: HOSETAIL15) inside each slide valve.
To allow the Tempest Filter to give the best performance, it is important that the flow rate is no more than the 5,000 litres per hour. Some of the installation examples show aby-pass that will enable you to increase the flow through the pond.

New advanced filtration media
Plastic media, for use in biological pond filters - specifically in moving bed bio reactors, was pioneered by Evolution Aqua, some 20 years ago. In recent years, other plastic media have come onto the market, usually with the aim of trying to get more and more surface area. However, one drawback to using plastic media has always been the time it takes to establish a stable biofilm – essential for good filtration.
After many years of research, Evolution Aqua have now developed a new media that not only gives class leading surface area, but also overcomes the problem of long maturation times.
K+Media is designed and manufactured in the UK 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 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.
Increased surface area
With a new shape and profile, K+Media has also been designed to have an increased and class leading surface area, meaning an overall surface area of 1,350m2 per m3. More importantly for biological filtration, the protected surface area of K+Media is 1,025m2 per m3. This allows a stable bio-film to form and remain intact when used in moving bed biological filtration, as in the new Nexus+.
Stable bio-film development
The shape of K+Media optimises the amount of “quiet zones” within the media where a stable bio-film can develop. Whilst K+Media keeps the integral profile of K1 Media at its core, there is an extra layer of cells and fins around the outside of each piece that enable microscopic organisms such as Rotifers and Vorticella to thrive. This is an additional benefit as competitor media do not have such “quiet zones” that would allow these higher lifeforms of filter feeders to develop. The bacteria and organisms that form within the bio-film ensure the media delivers optimum levels of biological filtration in the moving bed, which has been proven filtration technology for many years in the fishkeeping hobby.
