Build Your Own Aeration System

The most common ways of aerating ponds and lakes is either buy using a shore-mounted air pump, compressor or blower and feeding air into diffusers in the pond or lake. Placement of the diffusers depends on size, shape and depth of the pond or lake and the understanding of the ultimate goal of the aeration. Another method invloves surface aeration or fountain aeration. Ponds that are designed for raising fish will require a different aeration system than a decorative pond that is shared by multiple homeowners.Here you will find a selection of highly rated air pumps and diffusers as well as weighted airline and splitters to build a reliable aeration system for any sized pond or lake. Contact us if you require assistance with sizing of air pumps and placement of diffusers.
