The Aquatic Edge 40" flexible hose brush allows you to clean and maintain your aquarium hoses, easily and quickly. It will clean hoses up to a 5/8” diameter and up to a 36” length. Use it often to help maintain a clean and fresh aquarium.
Instructions: Disconnect hose. Insert the plastic cord end through the entire length of the hose so that it protrudes at the opposite end opening. Grasp the protruding end of the plastic cord and pull it through the hose until the brush exits the tube. Run warm tap water through the hose to flush any loosened particles. Repeat as necessary, until hose is thoroughly clean.
