Check out this link this is the system I put in and have great success with it. My pond is about 1 acre and about 8 or 9 feet deep. Another member on this forum used this same system though in 15 feet of water. Diffusers set at about 12 feet.
http://forums.pondboss.com/ubbthreads.php?ubb=showflat&Number=229082#Post229082I have about 350 bucks in it. Here is a quick list of what I have.
Eco Plus 7 pump.
75 feet of 5/8 th inch weighted hose from Ted Lea.
Self made base from the side of a computer and PVC spliting off 3 ways. Weighted down with 4 forklift wheel bearings.
3 9 inch fine bubble diffusers from diffuser express. They work great. Here are a few other pics.
Why do you think you need air in 3 different spots? Is your pond that oddly shaped? Just asking?
