Air Stream Diffuser

The Air Stream Diffuser for pond aeration is very efficient. It moves and degasses twice as much water with the same amount of air as the smaller 7” stone.

The Air Stream bottom diffuser easily moves hundred of gallons of water per minute from lower depths in a pond or lake bottom. By adding oxygen through an air diffuser, a gas transfer occurs which highly improves water quality and clarity. This degassing also removes foul smelling gasses and improves oxygen levels lower in the water.

How it works

The design of the air stream diffuser uses three 14″ small bubble diffuser tubes.  With the smaller bubbles, which break off faster, you will receive better gas transfer and more gallons of water movement.  This improved gas transfer using smaller bubble sizing will greatly reduce the nitrates, carbon dioxide and other gases in the water column.

24″ Tee Diffuser

Using an air lifting process for pond aeration, this Perforated Tubing Bottom Diffuser will de-gas and circulate large volumes of water per hour. Cleaning the water of algae feeding nutrients and growing good bacteria. Because of the larger amount of surface area the bubbles are smaller and the gas transfer is better. These diffusers are non-clogging as well. Bottom aeration moves hundreds of gallons per minute with only air.
