The Evolution Aqua Tempest Filter is primarily designed as a polishing system for ponds. It uses the latest EA filtration media, K+ Media, to produce crystal clear, healthy water. This filter can also be used as a stand alone filter for smaller ponds up to 5000ltrs as the K+ media acts as mechanical and biological filtration. Straight from the box this filter is easy to install as comes complete with everything you need. The Tempest filter is easy, simple and quick to clean, with their unique, patent pending air siphon design. Whiles in the cleaning process, air is drawn into the filter as it empties that causes the water to agitate, effectively cleaning the K+Media.

This filter works best when using the supplied K+Media. This media is capable of removing particles down to one micron! On a single pass, testing has proven that the media is capable of removing all particles down to 25 micron when used at the optimum flow rate. Not only that, the K+Media has been scientifically proven to have a much faster maturation time compared to most medias on the market.

How the tempest works:

Water is pumped up through the Tempest filter, Then the K+Media floats to the top of the filter, becoming a mechanical barrier that traps debris as it flows through the media. The waste is then trapped in the K+Media until the cleaning cycle dislodges it and it gets flushed away.

How to clean the tempest:

  1. Turn off the pump
  2. close both gate valves cutting off the inlet and the outlet
  3. Open the waste valve tap (located at the bottom)
  4. Close the waste valve tap once emptied
  5. open back up both slide valves
  6. Turn on the pump
