Scott Aerator Bubble Pro Max XL Sub-Surface Aeration System

Sub-Surface Aerators and Diffusers

Adding a sub-surface aeration system is the perfect way to increase your pond's or lake's water quality and oxygen levels while maintaining its natural appearance. Sub-surface aerators utilize diffuser modules that sit at the bottom of your pond and are connected by weighted tubing to an air compressor on shore. The compressor pumps much-needed air to the very bottom of the pond to de-stratify the water column and infuse oxygen into the water. The membrane on the diffuser breaks the air into tiny bubbles, which are released into the pond. As these bubbles rise to the surface, they carry the low-oxygen bottom water upwards, where it mixes with the oxygen-rich surface water. The constant mixing causes the water column to de-stratify, allowing harmful gases to be released into the atmosphere.

The Bubble Pro sub-surface aerators work great as pond de-icers as well. General rule of thumb for de-icing with a diffuser:  You’ll achieve a 2 foot wide circular opening for every foot of depth the diffuser is placed at.  Example: If placed at a depth of 1 foot, the diffuser will provide an opening approximately 2 feet in diameter. If placed at a depth of 5 feet, the diffuser will achieve a 10 foot circular opening.  Of course, this is an extremely general rule as temperatures will go up and down throughout the winter, and wind chills can play havoc as well.  The agitation of the diffuser pushes warm water from the bottom to the surface.  That warmth coupled with the water movement helps open up an area above the diffuser.

On extremely cold days and during periods with low wind chills it is not unusual for this opening to shrink or even ice over.  However, as long as the compressor is running, the ice will be thin and the air will be escaping through very small honeycomb holes in the ice.  Basically, stay off it and wait for the temperatures to come back up and the holes will open again.

Designed for easy installation, our aerators come with a two-year warranty on the motor and a five-year warranty on the tubing and diffusers. 

Bubble Pro Max XL Sub-Surface Aerator

Adding a sub-surface aeration system is a great way to boost water quality and oxygen levels while maintaining the natural appearance of your pond. This style of aerator has four diffuser modules that sit at the bottom of the pond, connected by weighted tubing which is in turn connected to an air compressor onshore. The compressor pumps much-needed air to the bottom of your pond, ensuring adequate oxygen levels during hot summer months.

Air is pumped from the compressor through the weighted airline to the diffusers at the pond bottom. When the air reaches the diffuser, several thousand small air bubbles are created. These bubbles rise to the surface and produce an upward current. Water at the pond bottom is lifted to the surface where oxygen is replenished by the atmosphere.

The Bubble Pro Max XL comes complete with four diffusers; four lengths of 100-foot by 3/8″ Quick Sink weighted tubing; a 3/4-hp, rocking-piston compressor; a valved air outlet assembly with individual controls for each hose and a pressure relief valve; and all required fittings and clamps. Designed for easy installation, the Bubble Pro Max XL comes with a two-year warranty. Also available for 230-volt power.

The Bubble Pro Max XL works as a pond de-icer too!
