Key features of the “Compact Series” (suitable for pump supply only) are the small footprint when space is restricted, coupled with the innovative design concept of incorporating an integral vortex style cavity for the settlement of solids – thereby reducing maintenance. Filtration mediums comprise of multi foam layers offering both mechanical and biological attributes, with high performance “Aquarock” forming the foundation for a biological bed for colonisation from beneficial bacteria. This range can also be used as a superb separate system for connecting to a skimmer unit. All units are supplied with a timber slatted lid, together with waste valve set.

The “Genesis” range of multi bay in-line filtration systems are available in 3 sizes, and whilst generally emulating the design concept and standards of the “CL” range they are better suited to the mixed ornamental pond, or the small Koi pond where high fish loads are not present. The range offers very good value for money, and with its neat design and low height is hardly ever obtrusive in any garden setting. Filtration mediums are the same as the “CL” range, with only genuine Japanese matting being used where applicable.

Size 1050 x 510 x 630mm. Suitable for Koi ponds up to 1,250 gallons (5675 litres), or Goldfish ponds up to 2,500 gallons (11,250 litres). This 2 Bay unit comprises of a vortex bay together with a biological/mechanical bay incorporating foam and the highly proclaimed aqua rock/alfagrog. This unit would also be very useful if fed from a skimmer unit on a larger pond. Note, all Genesis range are supplied with slatted timber lids. Note:- Pipe inlet size 110mm (4") - Outlet 82mm (3").

The F20 De Luxe Bio Clear model is 640 x 460 x 430mm high, and will cater for Koi ponds up to 1,200 gallons (5,350 litres) or Goldfish ponds up to 2,200 gallons (9,800 litres).

The "F20" model seen here could be expressed as a simple 3 bay unit, with the spraybar discharging into Bay 1 with its mechanical nylon brushes, with the water thereafter upflowing through Bay 3 with its biological "flocore" medium - following which the water downflows into Bay 2 (the central bay) travelling through the 3 layers of foam and the high performance biological "Aquarock" medium before returning to the pond. The filter comes complete with all media and fittings. A flushing valve is fitted to allow the accumulated waste at the bottom of the filter to be washed out with ease. The filter is 24"L x 18"W x 18"H (holds approx 25gall). A stepped hose allows any size flexi hose to be used for the inlet and the outlet is 50mm (2").
