Dennerle Nano FilterTubes, 500 ml

The Dennerle Nano Filter Tubes are a filter material for the external skim filter.

The Nano Filter Tubes are a powerful long-term filter medium for the Nano External Skim Filter and are suitable for both fresh and saltwater. Thanks to their large and porous surface, the tubes provide optimal living conditions for useful filter bacteria. The filter material becomes biologically active after a short time and thus ensures the efficient breakdown of ammonium and nitrite.

Application:
Before use, you should rinse the Nano Filter Tubes thoroughly with tap water to avoid abrasion caused by transport. You should replace half of the filter material every 6 months to ensure constant pollutant degradation.
