Oase ProfiClear Premium Discharge Module L

Final Stage Biological Filtration for ProfiClear Premium L Systems

The Oase ProfiClear Premium Discharge Module L is the final biological polishing stage within the ProfiClear Premium L modular filtration system. Positioned after the Moving Bed Module, it refines water quality before clean water returns to the pond.

Designed specifically for large koi ponds and high demand systems, this module increases biological processing capacity while stabilising water parameters. By incorporating high density ClearWave Blocks, it provides substantial additional surface area for nitrifying bacteria to colonise and mature.

As a result, ammonia and nitrite conversion improves, overall clarity increases, and system stability strengthens in heavily stocked environments.

How the Oase ProfiClear Premium Discharge Module L Works

Water flows directly from the Moving Bed Module into the Discharge Module through dual 150 mm inlets.

It then passes through densely structured ClearWave Blocks, which provide extensive biological settlement area.

Within this media:

• Ammonia is converted to nitrite
• Nitrite is converted to nitrate
• Dissolved organic waste is biologically processed

An integrated aeration connection allows optional air pump integration. When aerated, oxygen availability increases and biological efficiency improves further.

Finally, purified water exits through dual 110 mm outlets and returns steadily to the pond.

Technical information

Practical setup advice

Before ordering, think about how this product fits into the full pond setup. Compatibility, maintenance access, pipe or hose size and future servicing are often just as important as the headline specification. A product that is technically suitable can still disappoint if it is installed with restricted flow, poor access or the wrong supporting equipment.

Where possible, plan the main product and the accessories together. This makes installation neater, maintenance easier and the final system more reliable over time.

• Match the pump flow to the filter and pond volume, allowing for head height and pipework losses.
• Keep unions, valves and waste outlets accessible for cleaning and maintenance.
• Use suitable hose, pressure pipe or DN discharge pipework where specified by the manufacturer.
• Check compatible UV bulbs, quartz sleeves, media and spare parts before the pond season starts.

Plan this product as part of the complete filtration layout, rather than as an isolated item. Check the recommended flow rate, inlet and outlet sizes, waste connection, access for cleaning and the space needed for routine servicing before installation. A well matched filter system is easier to maintain and gives more reliable water clarity over the long term.

Filter setup notes

Compatible Oase Discharge Pipework

This Oase product uses DN-sized outlet or sludge-discharge connections, so it is worth planning the pipework before installation. Use the matching DN pipework for the connection size stated on the exact filter or module, and avoid reducing gravity outlets unless the system has been designed for it.

• Oase DN110 Filter Discharge Pipework
