David,

Letsrodeo and Theo are correct. The compressor needs to be an oiless rotary vane, piston or blower type. This removes any posibility of oil discharge in the water.

Secondly, you will burn out your compressor pretty quickly. It is not made to push volume of air but pressure. The pressure tank will drain quite rapidly and the compressor will be building it up continuously.

As for systems, the sky is the limit to what you want to do or I should say your wallet is the limit. I would look into the resource guid on the Pond Boss web page and start calling to size a system for you.
