The OASE BioTec 30 is a popular classic amongst Koi carp enthusiasts. Featuring a 4-stage filtration process and optional integration with a Bitron C UVC.
The water is firstly passed through brushes and mat meshwork to remove any coarse debris before reaching a series of filter foams, which house beneficial bacteria to assist in the breakdown of pollutants and nutrients. The filter foams vary in density staged from coarse to fine, allowing for particles to be removed from the pond water efficiently. The simple design and operation make this filter a low maintenance but highly effective Koi filter capable of filtering ponds up to a maximum volume of 120m³ (120,000 litres).
This filter requires a pump (not included).
