We’ve created our collection to be very similar to the K1 filter media and K3 filter media you might have purchased elsewhere previously. This plastic moving bed filter media is ideal for use in larger filtration applications, such as pond filters, where a large amount of biological filter media is required. Choose from different quantities, with both our K1 and K3 filter media available in 1 litre, 2 litre, 5 litre, 10 litre, 25 litre, or 50 litre bags. Use our compatible K1 or K3 filter media to encourage beneficial bacteria to colonise and subsequently help to remove harmful ammonia and nitrate levels from the water. 

K3 or K1 filter media is a great low-maintenance filtration option for your garden pond, as it’s designed to move freely within your filter. This constant movement helps it to self-clean, so there’s no maintenance required. If you’re not having to clean your filter as often, you won’t be risking losing as much of that beneficial bacteria growth, ultimately benefiting your koi pond further.
