Pond Boss Forums AERATION Systems questions Gast Rotary Vane Compressor Anyone using this ?

Ok great. I have had my eye on one. I am thinking about 3 Double stations 6 total Vertex 9" Disk . Do you have other recommendations on disk. I was thinking about building my own bases out of pvc . I have 230v Avalible is there any advantage running 230 over 115?
Thanks
