With PSS being the future its thought that demand for the technology will be such that the standard range of pump fed Cloverleaf multi bay filters with a conventional vortex will only be produced in very small numbers from 2007 onwards.

Explanation Of PSS: In brief Cloverleaf’s innovative but uncomplicated design for the PSS (Particle Separation System) can as a single bay/module be used in a stand alone situation (providing mechanical & biological filtration), and could also make a superb filter if attached to a skimmer. Alternatively the PSS (as a single module) can be hooked into any existing pump fed multi-bay filter system where it would replace any vortex bay - with any existing vortex then being converted into a bona-fide biological bay/chamber.

The key design concept of the PSS is to remove/trap suspended particles/solids from the water which would typically flow straight through many vortex bays and thus pollute any biological media. This is especially the case in that small diameter vortex units are not the ultimate in efficiency. In brief then the PSS can be classified as a highly refined vortex unit, which of course means that any existing filter (or bays) require far less maintenance - also meaning a greater biological bed is established. Who could ever argue that this is not a great asset worth having ?
 
Trapping of particles/solids is achieved via Cloverleaf’s uniquely designed and manufactured long life Particle Separation Media (PSM) which is retained in suspension at all times. When the PSM (media) becomes blocked it is time for it to be cleaned via the airstone ring, however any blockage which is visually indicated by water flowing up through the central overflow does not substantially reduce the flow rate through the rest of any filter system (where applicable) - so general flow rates/performance are never greatly restricted. Biological integrity of the PSM (media) is always fully maintained in that it is always ONLY ever cleaned via oxygen rich mature pond water.

Although Cloverleaf spent many months experimenting with numerous existing floating media from international sources, various shortcomings led to the final decision for the company to invest in expensive tooling costs in order to manufacture the PSM media at its own new Essex based factory - with the media design being based on that used by a UK national water supply utility company.
 
To summarise, the PSS is British at its best and contributes to a better pond environment together with less pond maintenance at a price that can only be described as most reasonable. Unlike perhaps some manufacturers the Cloverleaf design concept is not solely based on having to rip out and cast aside any existing filtration system, when the option does exist to retain any existing pump fed system if desired.
 
Please note air pump’s are not supplied as part of the PSS, but Cloverleaf’s C82 Air Pump is great for the job.

Cleaning of the media is achieved via the following easy steps:
(1) Close isolation valve on PSS bay
(2) Switch off submersible pump
(3) Activate air ring/air pump for several minutes
(4) Turn off air pump
(5) Immediately open PSS bay waste valve to discharge foul water
(6) Wipe top perforated plate in bay with a few sheets of kitchen roll paper
(7) Re-activate system

Do not clean the PSS unnecessarily. Only do so when the overflow is seen to be operational. If PSS1 or PSS2 is connected into an existing multi bay filter system and the media to that system requires cleaning then also close the isolating valve on the PSS first in order to prevent foul water from running back to the pump.

Please make reference to the above explanatory text together with the diagram and adjacent photo (on left) for an understanding of how all PSS filters are constructed & function.

The PSS1, PSS2 and PSS3 models are stand alone modules based on Cloverleaf’s existing VH2/1, VH3/1 and VH4/1 pumped fed “Compact Range” filter units. As mentioned above, these 3 filters can be used in various applications including solely on their own, linked to a surface skimmer device, or connected into an existing pump fed multi bay filtration system. On the latter setup any existing vortex bay should thereafter be converted into a biological bed.

Refer to adjacent diagram (on left) for reference on connecting a PSS module into an existing pump fed multi bay filter.

Incorporation of the PSS advanced technology into the CL Professional range has meant a far greater increase in filter efficiency to the degree that maximum pond capacity ratings can be increased by 100% beyond the standard CL range. This means the ADTEC - CL2 is suitable for Koi ponds up to 5,000 gallons (22,500 litres) or Goldfish ponds up to 10,000 gallons (45,000 litres). The ADTEC - CL3 is suitable for Koi ponds up to 7,500 gallons (33,750 litres) or Goldfish ponds up to 15,000 gallons (67,500 litres) with the ADTEC - CL4 being suitable for Koi ponds up to 10,000 gallons (45,000 litres) or Goldfish ponds up to 20,000 gallons (90,000 litres). All of these ratings are naturally subject to Cloverleaf's standard guidance notes on fish loads, pond depth etc, as described elsewhere on the website.

The stated efficiency or performance gains are possible principally due to the PSS media (or PSM) preventing contamination of biological media in other bays. Whilst the prime function of the PSM is to act in a mechanical capacity the media itself also has a large biological capacity, especially when the media cleaning process only ever involves mature pond water and compressed air (oxygen). Furthermore it should be noted that the conventional brushes (installed as standard to bay No2) are not needed for mechanical filtration purposes, and thus via protection from the PSM will act as an additional quality biological bed.

The diagramatic drawings (shown on the left) illustrate the flow pattern and media arrangement for any 4 bay ADTEC filter, with a further diagram illustrating how the pump fed filters can be sunk below ground level and connected up to a bottom drain.

Price Notice: As a rough guide the optional integration of the PSS into standard filters like the CL4  will increase costs by approx 15%.
