Oase BioSmart Set 14000
Foam filtration and UV for a garden pond
The BioSmart Set 14000 combines filter foams with a 11W UV clarifier. The foams catch debris and support filter bacteria; the UV helps control suspended algae that turn the water green.
This set includes the Filter Pump 3500, rated at 3,400 litres per hour maximum, and 3 metres of 19mm hose. Plan the return and waste pipework to suit your pond.
Choose the stocking rating that fits
Oase lists up to 14,000 litres without fish, 7,000 litres with fish and 3,500 litres with koi. These are maximum guidelines. Fish numbers, feeding and sunlight can change the filtration needed.
Plan an unrestricted gravity return
Water is pumped into the filter and returns to the pond by gravity. Keep the DN 75 outlet and return route clear, with the necessary fall. Allow room to lift the lid and reach the cleaning handles and waste connection.
The filter can be recessed by up to one-third of its height when the installation still allows the correct return level and access. Check the whole pipe route before setting the base.
Cleaning and water checks
The external handles let you compress the foams in the housing and release dirty water through the sludge drain. The soiling indicator helps with cleaning; it does not measure ammonia or nitrite. Test the pond water while a filter is maturing and after changes to fish load or equipment.
Keep the UV quartz sleeve clean and replace the lamp as instructed. Isolate the UV before servicing or draining its water chamber. Clear-looking water alone does not establish good water chemistry.
