Dennerle Nano Filter Extension

The Dennerle Nano Filter Extension is a clip-on additional filter for the Nano corner filter and Nano corner filter XL.

Bacteria play a crucial role in the biological balance. It is these invisible helpers that continuously eliminate fish excretions, plant and feed residues. Each type of bacteria specialises in certain substances. Therefore, only the "right" bacteria guarantee the quick and safe breakdown of the waste materials typical of aquariums.

The Nano filter extension can be attached to the Nano corner filter or the Nano corner filter XL in a few simple steps and is particularly recommended for fish stocking. It increases the filter performance or can be used for short-term additional filtering with phosphate binders or activated carbon.

Application
Fill the nano filter extension, rinse it briefly for possible transport-related abrasion and clip it on. You can fill it with nano filter media such as the biofilter granulate, algae stop or active carbon.
