Pond Boss Forums AERATION Systems questions Cautious diffuser placement question

Thanks for the recommendation!

We have run air line underground over 1,200 feet to a pond. We were pushing more air than you need, and we went with 1 1/4" poly tubing for the run. While you might be able to get away with the 5/8" tube, I'd feel better if you ran 1" i.d. tubing. Less restriction over that length run, and less chance for a dip in the tubing to collect water during the winter and freeze.

I have a client that is using 3/8" ID tubing to run 900' to his pond, but he is only pushing 1 CFM of air that distance and he is seeing about 3 PSI back pressure from the friction of the air going through the line. He also has problems during the winter of it freezing up and plugging. We installed a anti fre3eze system from Koenders to solve that problem. It injects Isopropyl Alcohol into the line to prevent it from freezing.
