Frequently Asked Questions

Follow the steps below to clean the Tempest filter:

STEP 1: Switch pump off.

STEP 2: Close all slide valves on inlet and outlet.

STEP 3: Open the tap(s) on the waste valve assembly. Air enters the filter causing the filter media to move and clean as the water drains to waste.

STEP 4: Once the water has emptied from the filter(s) and the media sinks to the bottom, close the tap(s) on the waste valve assembly.

STEP 5: Open all slide valves on inlet and outlet.

STEP 6: Turn pump back on. Water will re-fill the tube and media will rise to the top.

Tempest Filter - Cleaning

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.

Total surface area = 1,350m2 per m3

Protected surface area = 1,025m2 per m3

Diameter = 10.2mm

Length = 8mm

 

 

 

1. Check the air valve is not blocked.

2. Check the slide valves are fully closed.

3. If the media is very dirty this may cause the pack to clump together.Multiple cleans should clear this.

4. If the white end cap at the bottom of the filter is full of waste it is possible to clear this by switching off the pump and unscrewing the waste valve assembly, allowing the blockage to clear.

It will take a few days before the media starts to behave as it should. During this time it is likely to clump together and not agitate freely during cleaning. This will only last a few days.

The white end cap at the bottom of the filter may be full of waste. It is possible to clear this by switching off the pump and unscrewing the waste valve assembly, allowing you to clear the blockage.

Check the O-ring is seated correctly on the inside of the waste valve assembly.

The white end caps at the top and bottom of the filter are glued on. It is possible to unscrew the waste valve assembly at the bottom of the filter once the pump is turned off and the filter has been emptied during a cleaning cycle. This will allow you to access the inside of the cap to clear out any waste or debris. There is a grill plate inside the end cap to prevent the media escaping which can also be cleaned carefully. The inside of tube will clear accordingly every time the media in the Tempest is cleaned and water flushes to waste.

The Tempest arrives pre-filled with 7 litres of K+Media. You also receive the waste valve assembly, which simple screws onto the bottom of the filter, two slide valves and connection pipes which must be fitted using solvent weld adhesive to the inlet and outlet, and two pipe clips to help wall mount the filter. Wall fixings are not provided.

The tempest can be installed with the return below the water line as it returns the water back to the pond under pressure.

We would recommend fitting a one way valve between the filter and the pond so that it doesn’t syphon back from the pond when the tempest is turned off.
