Founded by Robert "Bob" Heideman in 1978, Aquatic Eco-Systems Green, Inc., started as an Orlando-based lake improvement company specializing in aeration and destratification. Through his research, Bob developed highly efficient synergistic airlift diffusers for lake aeration.

The company branched out from lake aeration and began to sell aquaculture, aquarium and pond and water garden products as well. AESG quickly became known across several aquatic industries as a premium source of goods and technical advice. Their cost-conscious philosophy—recycling packaging material, buying in bulk, focusing on energy efficiency—resonated with a community passionate about economy as well as ecology..

Many of the top aquatic system designers around the world started using AESG’s equipment and expertise to build everything from public aquariums to fish hatcheries. The company proved that it was able to serve them while keeping its commitment to less experienced customers and everyday aquatic needs. Further becoming a source for all things aquatic, AESG added system design and equipment repairs to its list of services.
