Biotec 5.1 / Biosmart 18000 filter foam set

Set of genuine OASE Filter Foams.  The filter foam set consists of 2 x blue (Coarse grade) foams, 1 x red (Fine grade) foam and 1 x green (anaerobic) foam.  Suitable for direct replacement in the following OASE Pond Filter Systems:

• BioSmart 18000 Pond Filter
• BioTec 5.1 (now rebranded as the BioSmart 18000)

Please note that it is important to use genuine replacement sponges as cheaper replicas can drastically reduce the filter performance, both mechanically and biologically.
