250mm, 500mm & 1000mm Air Tube Diffusers
These Air Tube Diffusers are designed to be a dropped in your water system, they come with a rubber membrane which is wrapped around a hollow PVC tube.
It is naturally buoyant so you may also add small stones to the inner tube to increase weight so it stays put on the bottom of your pond or lake should you wish to ground it. The air slots provide a steady flow outlet to maximise aeration.
These tubes are commonly used in waste water treatment systems, aquariums and hydroponics systems.
To clean, simply wipe with a rag and clean water occasionally.
