Well I finally decided on a system and hope I didn't do wrong. Found a dealer half way across the country who took some time with me and found a good solution for me. I'm getting a Vertex Air 2 system except without the Vertex cabinet. Instead I'm getting a cheaper "Poly" cabinet with a fan and ventilation built in.
The dealer realized that I was just putting the cabinet in a barn on a farm so suggested to me that I really didn't need to spend the extra money on the fancy Vertex cabinet but he strongly recommended their equipment. So all the components; compressor, diffusers etc. are the Vertex system.
He managed to convince me that I am better off biting the bullet and trenching. Considering I have access to a friend with a backhoe who has offered to trench for me, I might as well do it. Now he did suggest burying it 2.5 feet deep so I guess I'll do that. The land is flat so it can't be uphill to the compressor unfortunately.
I guess I could install a check valve at the compressor. Is this what you mean by a water trap Bill?
I've had quite a bit of farm runoff into this pond over the last few years. I made the mistake of not fencing it off from the cattle and since I got the cattle, weeds and algae have exploded. Suspect getting the water moving will do it some good. Cattle have been put up for sale so the situation won't continue.
