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. This is where the ‘Fluidised Bed Filter’ comes into its own, and providing that the existing system can adequately cater for mechanical filtration, then a vast improvement in water quality parameters will be evident. As a guide to flow rates and application of use, approximately 10% of the ponds volume should be directed through the Fluidised Bed Filter.
The ability of Fluidised Bed Filters to biologically cater for extremely high level fish loads has been well documented, Cloverleaf offer the very best in FB’s – assisted greatly by the unique specification of biomass used, and which is scientifically known to offer superior bacteria colonisation than that achieved by coral sand and other common types. Put into perspective, studies would indicate that the unique Cloverleaf biomass 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. FB’s should only be installed on existing mature ponds where adequate mechanical filtration also exists.
The M25P pressurised throughout FB unit will cater for heavy stocked ponds up to 2,500 gallons (11,250 letres) – with an ideal final operational flow rate of around 200/250gph. This unit is approx 600mm hgih (24”) with a 110mm (4”) diameter core containing 3kg of biomass, together with standard 38mm (1.5”) pipe manifolds including 2 ball valves. The M25P will support up to 50kg (110lb) of fish load.
The M70P pressurised throughout FB unit will cater for heavy stocked ponds up to 7,000 gallons (31,500 letres) – with an ideal final operational flow rate of around 700gph. This unit is approx 1000mm high (40”) with a 110mm (4”) diameter core containing 6kg of biomass. The superb 2000mm high M140P will support up to 200kg (440lb) of fish load in ponds up to 14,000 gallons (63,000 letres).
