| Introduction To The CL Professional Range | |||
| Few manufacturers in the world have put as much effort into designing a flexible and good value range of multi-bay filters suitable for the Koi pond as Cloverleaf, and how refreshing to not only know that they are British but to acknowledge they offer first class technical support to customers/end users. Key features of this well constructed compact "CL" range are the options of the filters being pump or gravity fed (meaning below ground), whilst being very simple to maintain. The incorporation of vortex bays, and skilful use of mechanical and biological bays using quality mediums encompassing good water flows are further attributes that make the range a superb and sound investment. For very large ponds all filters can be happily installed as pairs - linked to separate pumps or bottom drains. All systems are supplied complete with valves and waste kits, together with a heavy duty lid | |||

This drawing illustrates the general design concept to both the Cloverleaf “CL” and “Genesis” range. As can be seen key beneficial features are numerous, starting from the principles of up and down flow through the tanks thereby keeping the water in contact with the mediums for as long as possible. Apart from the advantageous separation and settlement of solids in the vortex bay, the generation of an “upflow” and the incorporation of settlement areas (with drain down valves) ensures that the filtration mediums stay cleaner for longer – thus promoting larger colonies of beneficial bacteria, and by default thereby establishing a healthier pond environment. The thoughtful design layout of the vertical transfer ports also provides the highly useful bonus of being able to incorporate air stones (where desired) without the need for the pond to appear similar to a witch’s cauldron. | ||

This image of a green Cloverleaf CL2 (with lid removed) will better illustrate the option of adding aeration via a separate airpump and airstones. This technique is highly desirable where heavy fish loads exist. | ||

This 4 Bay unit comprises of a first stage vortex bay, with Bay 2 being fitted with mechanical brushes, Bay 3 acting as a main biological bay with a Japanese Matting and Bay 4 serving as the secondary and final biological/mechanical stage - incorporating foam and the highly proclaimed aqua rock/alfagrog. Note:- Pipe inlet size 110mm (4") - Outlet 82mm (3"). | ||

Size 1220 x 1220 x
860mm. Suitable for Koi ponds up to 3,750 gallons (16,875 litres), or
Goldfish ponds up to 7,500 gallons (33,750 litres). General description as
for “CL2” filter. Note:- Pipe inlet size 110mm (4") - Outlet
110mm (4").
Note: CL1, CL2, & CL3 are supplied complete with heavy duty lid, together with waste valves and pipes.

| Below: Cloverleaf CL4 | |||
|
Size 1600 x 1600 x
1200mm high. Suitable for Koi ponds up to 5,000 gallons (22,500 litres),
or Goldfish ponds up to 10,000 gallons (45,000 litres). As standard this
system is supplied without a lid, and without any filtration mediums – thus giving
the pondkeeper full flexibility in choice. A "CL4 Optional Media Kit"
is available at extra cost as shown on the diagram with 28 Brushes, Jap-Mat, Foam & Aquarock.
General description as for
“CL2” & “CL3” filters. Note:- Pipe inlet size 160mm (6")
- Outlet 100mm (4").
The site installation of the CL4 model is unique to the range, in that pressures on the casing welds brought about by the weight of water (approx 1 ton per bay without media) requires that the unit needs to be placed on a firm level concrete base, and partially encased in concrete to provide lasting stability and a long life. This applies regardless of whether the unit is pump or gravity fed, and the attached diagram illustrates the basics of what needs to be achieved. Should any further technical clarity be required do not hesitate to contact the Cloverleaf office. |
