Scott Aerator Sub-Surface Aerators

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.

Designed for easy installation. They're great as pond de-icers too!
