The dilemma of very high fish stocks overloading an existing filter system has frequently meant replacing the entire system or adding to it in a conventional manner, but often the case is that there is insufficient floor space (or finances) to execute either option. This is where the economical Fluidised Bed filter fully comes into its own, and providing that the existing system can adequately cater for mechanical filtration, then a vast improvement in water quality will be evident.

The ability of Fluidised Bed filters to biological cater for extremely high level fish loads has been well documented, . Only after considerable field and laboratory research can Cloverleaf offer the very best in FB’s – assisted greatly by the unique specification of silica sand used, and which is scientifically known to offer superior bacteria colonisation than that achieved by coral sand and other common types used. Studies would indicate that the unique Cloverleaf biomass silica media has such impressive properties that 3kg will support the same volume of beneficial bacteria that might otherwise only be achievable if using 50 sacks of average filter rock or gravel.

Cloverleaf FB’s are manufactured in 3 varying sizes, and are available in two designs – (1) Pumped with gravity return (2) Pumped with pressurised return. Unlike some other manufacturers products the Cloverleaf range incorporates a non return valve to prevent the loss of sand via any siphoning actions.

As a guide to flow rates and application of use, approximately 10% of the ponds volume should be directed through the Fluidised Bed filter. By the nature of design and media used FB's should only be installed on existing mature ponds where adequate mechanical filtration also exists.

Fluidised Bed Type M25 - Gravity Return

Fluidised Bed Type M25 - Gravity Return
Ref: CLFBM25
The M25 gravity return FB unit will cater for heavy stocked ponds up to 2,500 gallons (11,250 litres), and is best served from a high pressure pump offering around 470gph (lsuch as Blagdons Amphibious P2000) – with final operational flow rates of around 250gph. This unit is approx 600mm high (24”) with a 110mm (4”) diameter core containing 3kg of silica sand, together with standard 38mm (1.5”) inlet pipe manifold including a Cloverleaf Side Valve on the inlet side, together with a non return valve. Outlet/gravity return is for 50mm (standard 2") rigid pipework. The M25 will support up to 50kg (110lb) of fish load.

Fluidised Bed Type M140 - Gravity Return

Fluidised Bed Type M140 - Gravity Return
Ref: CLFBM140
The M140 & M140P (pressurised) will both cater for heavy stocked ponds up to 14,000 gallons (63,000 litres). These impressive units are approx 2000mm high (80") with a 110mm core (4") containing 12kg of silica sand. The M140 model requires a 1/4hp pump (similar to that used on the Cloverleaf Junior Pondvac) with an operational flow rate of around 1,400gph. Remaining pipe specification of M140P is similar to the M70P. The M140P will support up to 200kg (440lb) of fish load.
