Venturis

A venturi is a device that injects air into your pond water to ensure adequate pond aeration.

Water is pumped through the venturi, and the restrictor creates a vacuum that sucks air in from the tube above water level, and then mixes with water inside the venturi to cause bubbles that aerate the pond water. It is used to improve pond aeration and movement of water in the pond and increase the oxygen level in the water.
