This water stone is designed in such a way that the air is divided into many small bubbles. This ensures that the oxygen is easily absorbed into the water and the water is properly set in motion. This small bubble stone can be connected to an air pump with a 4/6 mm air hose and is suitable for smaller aquariums. It is advisable to always fit a check valve to ensure that the water cannot flow out of the aquarium via the air hose. Suitable for both freshwater and saltwater.
