KK3500 media has a surface area ratio of 3,500m2 per m3, thanks to its circular design or ridged edges, giving a surface area that is unrivaled for bacteria. 

KK3500 can be easily installed into a standard biological filter or moving bed filter, and can be retro-fitted to existing systems to enhance performance as well.

This media comes with the largest surface area available, meaning better bacteria capacity within the system which will really benefit your pond filter as nitrogen and ammonia broken down more quickly, to a less harmful nitrate, keeping the water quality at its very best, and benefiting any fish within.
