Dennerle Corner Filter Replacement 3 pieces

Pack of 3 original Dennerle replacement filter cartridges for Nano and Nano XL corner filters. 3-layer, large-surface fabric for efficient filtration and consistently crystal-clear water.

💡 Expert tip: Replace the cartridge at regular intervals to maintain maximum filter performance. Having a stock of 3 pieces is the right choice: you'll never be without a replacement when you need it, and the biological filtration of the tank will always remain active.
