Dennerle - Replacement Rotor for Nano Corner Filter

Original Dennerle replacement rotor for Nano corner filters. An essential component to always have on hand to ensure continuous filter operation.

💡 Expert tip: The rotor is the component subject to the most wear in any internal filter. Keeping it as a spare prevents sudden interruptions in filtration, which even for a few hours can stress fish and compromise the biological balance of the tank.
