Fluval C-Nodes C2/C3 100g 14023 Fluval C2/C3 C-Nodes Biological Filter Media 100g for Fluval C2/C3 Hang On Filter Customer Rating  N/A Add Review Ask Question $15.95 Qty : < > Product Description Reviews (0) (View All) Questions (View All) Fluval C-Nodes feature a complex pore system where beneficial bacteria will thrive. Their unique star shapes provide a higher filtration surface and more biological power than most biological media, resulting in a healthy aquarium environment. Directions: Remove protective plastic bag and rinse C-Nodes thoroughly before use. Place them into biological trickle chamber. Over time micro and macro tunnels of the C-Node pore system will become clogged. It is suggested to lightly rinse with aquarium water or replace 1/2 the quantity every 6 months. Never replace all the C-Nodes at one time, as the valuable colonies of beneficial bacteria would be lost. 100g Add Review There are no reviews for this product.
