The Hozelock Medium Air Stone is designed to produce a steady stream of fine air bubbles when connected to a compatible air pump using 4mm airline. Ideal for increasing oxygen levels in ponds and water features, it helps improve water circulation and supports a healthier aquatic environment.

Manufactured from a durable ceramic compound with a plastic hose connector, this heavy-duty air stone is built to sink to the bottom of the pond, allowing bubbles to rise through the water and break the surface. It is suitable for use with a wide range of medium air pumps, including the Hozelock Air Pump 1500.
