Dennerle Nano Corner- filter Replacement Cartridge, 3 Pcs

Your fish and all other residents should feel as comfortable as possible in an aquarium because this is where they spend their entire lives. Good water values are therefore crucial for good health. If these are not correct, the animals can become ill and possibly even die. In order to achieve good water quality, it is necessary to regularly reprocess the water in the aquarium. Especially when refurbishing, but also when changing partial water, it is, therefore, necessary to prepare the tap water to suit the fish and also to replace filter media from time to time.

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.

With the replacement filter element, you can easily replace your filter medium in the Nano corner filter and the Nano corner filter XL. The large surface is ideal for filter bacteria, the filter performance is excellent and contributes to crystal-clear and healthy water. The 3-layer special fleece is used for efficient filtering and reliably holds back suspended matter and small particles. You should replace the filter element at regular intervals in order to ensure permanent good operation.
