Description
The BioSmart 18000's large filter foam surface ensures clean, clear pond water. The in-situ foam cleaning mechanism enables convenient cleaning of the filter foams without the need for removal from the filter box. An integrated pollution level indicator signals the right time for cleaning. The addition of an optional Oxytex pond aerator will further improve the water quality and health of fish, other aquatic life and plants, and it will improve filter performance by up to 25%.
- Maximum flow-through 5500 litres/hour
- Special filter foams (red and blue) for highly effective nitrification, as well as for de-nitrification (green)
- Cleaning via the sludge drain by simply pulling the integrated slide valve
- Long service life thanks to high-quality materials in functional design and first class workmanship
- Integral thermometer to monitor water temperature

Biosmart filters include Oase distinctive filter foams, with maximum surface area for beneficial bacteria, which transform toxic ammonia and nitrate into harmless nitrogen. Foams are easily squeezed clean, in situ, by the innovative compression mechanism | Integrated UVC Technology The integrated ultraviolet clarifier (UVC) ensures safe elimination of algae and pathogens on the Biosmart 7000 & 14000 filter models. | The optional use of OASE BioKick filter starter will dramatically increase the amount of beneficial bacteria within the BioSmart Filter and will colonise the filter foams to help break down waste matter organically. | ||

Pond Turnover Rates: The pond stocking levels will determine the required turnover rate which in turn determines the required pump flow rate. Typically, an ornamental pond without any fish will require the pond volume to be circulated at least once every 6 hours; an average stocked pond (with up to 1 kg of fish for every 1000 litres) will require circulating once every 4 hours; a heavily stocked pond including Koi (with up to 3 kg of fish for every 1000 litres) will require circulating once every 2 hours.
Pump Flow Rate: The pump flow rate, typically in litres per hour (lph) or litres per minute (lpm) is determined by the vertical lift, in metres, from the surface of the pond to the outlet pipe AND by the friction losses through the system. The narrower the pipe bore the higher the friction losses, so always use the maximum hose diameter.
Effect of raising the filter outlet: Raising the filter outlet pipe height, typically for a watercourse or waterfall, will reduce the flow rate from the pump thereby increasing the amount of time it takes to circulate the dirty pond water through the filter. This effectively reduces the maximum pond volume that the filter system can cope with and may mean you will require a larger pump. Please contact us and we would be happy to advise you.
Dissolved oxygen (DO) is a major contributor to water quality. Installing an optimally sized OASE OxyTex Aerator Set will substantially improve water quality and fish and can improve filter performance by up to 25%. See the chart above for improvements in pond volume.
The importance of regular maintenance (cleaning): High flow rate = effective filtering. As the filter media (e.g. foams) remove dirt and waste from the pond, so the friction loss across the foams will increase, thereby reducing the flow rate and the effective performance of the filter. It is therefore essential to keep the filter foams clean.
