Bottom Aeration

Why Bottom Aeration Matters

Bottom aeration creates healthy ponds with clean, clear water. This low-pressure, high-volume process infuses oxygen into pond water while releasing unwanted gases. It provides constant circulation to prevent algae and muck buildup, reduces mosquitoes, and creates ideal conditions for fish and plants. In winter, it keeps a hole open in the ice for essential oxygenation.

Adding an Anjon or Savio system gives you healthier fish, cleaner water, less odor, less muck, and an overall healthier pond environment.

Lake Aeration Benefits

Aerating a large pond or lake can seem overwhelming, especially when it spans several acres. A lake naturally collects runoff, organic debris, and waste from its surroundings. Over time, this material settles on the bottom, where it decomposes, creates odors, and releases harmful gases. Because a pond can't be vacuumed or sealed off, aeration is the most effective and environmentally friendly solution.

There are two main aeration methods: surface aeration, which uses fountains or circulators to oxygenate only the top layer of water, and bottom aeration, which circulates and oxygenates the entire water column from the pond floor 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.

Sizing Your Aeration System

General Rule: Most systems use 1 diffuser per acre with 100 feet of airline.

Complete kits are available for lakes up to 6 acres. For larger or uniquely shaped lakes, contact your Anjon Sales Representative for a custom consultation.

Key Factors:

• Lake size (acres)
• Average and maximum depth
• Lake shape and bottom contour
• Distance from power source to diffuser locations
