Remove protective plastic bag and rinse C-Nodes thoroughly before use. Place them into biological Trickle Chamber. Over time the micro and macro tunnels of the C-Node pores system 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.
