You don't need a lot of Hp to aerate your pond. Depending on the diffuser type and required cfm, you could aerate your pond on 1/3 Hp piston compressor. You might want to consider using a membrane type diffuser rather than air stones. They require very little cfm and maintenance. What is the size and depth of your pond?
