Filter material for the Dennerle corner filter - optimal solutions for every filter problem

The Dennerle corner filter for nano aquarium is equipped with a filter element made of fleece as standard. Here in the online store you can get replacement filter elements for the corner filter, by which you can replace clogged filter elements. We also have other solutions that you may need, for example, if the aquarium is more crowded.

For example, if you would like to significantly increase the filter area and the settlement area for the filter bacteria, the Dennerle Nano Bio FilterGranulate is a good choice. Please note when purchasing that you absolutely need either the Nano Filter Extension or the Nano Filter Module for the corner filter to use this porous filter granulate!

Thanks to the fine pores, enormous amounts of pollutant-degrading bacteria can settle on the granulate, which effectively biologically clean the aquarium water in your NanoCube and free it from ammonium, ammonia and nitrite.

Algae plagues are history with the Dennerle Nano AlgenStop. This filter medium removes phosphate from the water, thus taking away one of the main nutrients from algae. In doing so, you limit excessive algae growth and strengthen the algae's competition: Your aquarium plants. Nutrient imbalances often lead to algae growth, and with the Nano Algae Stop filter granulate from Dennerle you can effectively curb algae growth. The phosphate remover is either filled into the Nano Filter Module or into the Nano Filter Extension.

Nano Active Carbon is used to remove pollutants from tap water or medication residues, for example from planarian control, but also to remove water turbidity and yellowish discoloration - these are small pellets of activated carbon that do not release algae-promoting phosphates and do not get dirty. They fit perfectly into the Dennerle corner filter - either in the filter module or in the filter extension.
