Aquarium and pond inhabitants need oxygen to live. Air stones, also called diffusers, transport air from a diaphragm pump (air pump) into the aquarium or pond. The air bubbles from the air stone into the water to the water surface. The air bubbles release oxygen to the surrounding aquarium and pond water on their way to the surface and also move the water surface. The water surface becomes larger due to the movement and can absorb more oxygen from the air.
