JBL PROSILENT a400: Powerful air pump with 2 connections for perfect aquarium aeration

Air pumps (also called diaphragm pumps) pump air into the aquarium or pond. The air enters the water through air stones and thus increases the oxygen content. Partly through the small bubbles dissolving oxygen into the water on their way to the surface, but mainly through air bubbles moving the water surface as they rise and thus increasing the surface area. The larger surface area enables a greater uptake of oxygen from the air.
