Bottom Aeration

Why Aerate Your Lake?

Lakes collect rain, fertilizer runoff, waste, and organics that rot at the bottom, creating odor and harmful gases. Bottom aeration is the most eco-friendly solution—it oxygenates the entire water column, reduces muck, prevents fish kills, and keeps water healthy from the lake bed to the surface.

How Bottom Aeration Works

Compressed air travels through weighted tubing to diffusers at the lake bottom, creating millions of tiny bubbles that rise and mix water layers (thermocline). This oxygenates deep water, helps bacteria digest muck, releases harmful gases like ammonia at the surface, and keeps water moving to prevent stagnation and mosquitoes.

System Components

Compressor

Housed in a cabinet near power. Contains compressor(s), air manifold, cooling fans, and connecting airlines.

Weighted Tubing

Delivers air from compressor to diffuser. Weight keeps tubing anchored at the lake bottom.

Diffusers

Receives air and diffuses it into tiny bubbles that aerate the entire water column from bottom to surface.

Sizing Guide: Most systems use 1 diffuser per acre with 100 feet of airline. Complete kits available for lakes up to 6 acres. For larger or uniquely shaped lakes, contact your Anjon Sales Representative for consultation.
