Dennerle Nano Bio FilterGranulat
Grain size: 2-4 mm
Contents: 300 ml
Nano Bio FilterGranulat is a powerful, long-lasting filter material for breaking down harmful substances in the aquarium. The granules consist of baked clay minerals with a very porous structure. This provides a very large adhesion surface for bacteria, which makes good biological filtering possible.
Use Nano Bio FilterGranulat to fill a Dennerle Nano FilterModule or FilterExtension. Rinse the granules thoroughly to remove any grit caused by transportation. For maximum and continuous performance, half can be replaced every 3 months. With a 300ml capacity, the FilterModule or Extension can be filled 3 times.
