Spencer welcome aboard. Your pics help alot along with your descriptions and goals. Your two pronged approach with aeration and tilapia are wise.As far as aeration and doing it yourself look into two airstations with your depths. I can suggest a standard Vertex Coactive model for the deeper bowl and a Shallow water model for the neck. A compressor that supplies from 2.5 cfm to 4.2 cfm will be plenty. This can be from a 1/4 hp to a 1/3 hp rotary vane or a wob-l piston type compressor depending on how long your lines will be from the compressor.As far a a manifold and valve setup feel free to look at our Economy Series for ideas on how to build your own.Let us know any other questions you may have.
