Jardin Aquarium Water Filter Pipe Air Tube Hose Cleaning Brush

This little brush would have been perfect for cleaning the hoses on my Rena Filstar if the cable had been longer. The brush itself is just the right diameter, about an inch. The cable is made of a somewhat stiff clear plastic and is 3 ft long. It's stiff enough that you can push the brush into the hose if the hose is too long to thread the cable through and pull it out the other end, or if you want to clean the inside of the Filstar's output bar. It was a little too stiff to work through the elbows in the Filstar's input and output assemblies, so a longer cable to push through from the opposite end would have been helpful.
