Overview
Product description: Kaldnes 8 wings are constructed with an 8-branch flower structure, with a diameter of 16mm, a length of 10mm, and a contact surface of 800 m2/m3. Suitable for large filter tanks that require moderate high performance and energy efficiency. Please note that the biofilm adhering to the surface of the particles needs 7-15 days to stabilize before easy movement occurs. Also, pay attention to the placement of the aerator and mixer, as well as their intensity, to ensure suitability.
This product gear is commonly used for freshwater planted tanks, nano aquascapes, and routine maintenance — always match capacity to your tank volume and livestock.
