Pond Filter Media

Proper filtration is essential for maintaining clear water and healthy fish in both garden ponds and home aquariums. We offer a wide selection of top-quality mechanical and biological filter media to optimise chemical, particulate and toxin removal from your pond or tank.

Choose from various foam, sponge and mat configurations to capture debris and particles as water flows through. Filter floss pads polish water and remove fine sediment. Bio-media like K1, bioballs and textured ceramic shower media promote growth of beneficial bacteria that processes waste and converts toxins.

Media tailored for koi ponds filters out larger waste while aquarium media focuses on creating crystal clear water. Shop by pond size or aquarium volume to meet your specific filter needs. Keep water purified and fish healthy with premium filter media for all freshwater applications.
