Use this innovative filter for crystal clear pond water.
Easy to install, this new filter from UK brand Evolution Aqua has a unique patent pending air syphon design to simplify cleaning. The filter contains hi-tech K+ Media that are agitated and cleaned by air that is drawn into the filter as it empties. Particles down to 1 micron in size can be filtered out by the K+ media.
Water is pumped into the filter from the pond and the floating K+ rises to the top of the filter body forming a mechanical barrier to trap the debris in the water. The waste stays there until the cleaning cycle disturbs it and it is then flushed away.
Cleaning is easy, turn off the pump and open the waste valve. Air is drawn into the filter, causing turbulence in the water to dislodge any trapped waste. The dirty water then exits the filter leaving only the cleaned media behind. It is important that the filter is installed upright for this to work properly.
Multiple Tempest filters can be installed in parallel on larger ponds, they can be used as the sole filter or alongside another filter to improve clarity.
