Pond Boss Forums AERATION Systems questions 1/4 HP pond aerator pump

Try calling one of the aeration companies. It's not only about the pump size, it's about how many CFM air it can furnish at the depth that you will need to place your diffusers.

For instance a 25' deep pond will need a rocking piston type compressor whereas a <15' deep pond could use a rotary vane compressor.

Look at the warranty and ease of rebuilding too, AND if parts are available to rebuild the compressor. We are distributors for Vertex and Stoney Creek aeration supplies. Compressors we sell are from 1/20th hp to 1 hp.
