Well I have not had air for long but I have had it for 4 years now. I can tell you this from what I have seen.
1. My pond does seem to be cleaner.
2. My fish do seem to be more active and in GREAT shape and color.
3. I am holding more fish now with air than I could without air running.
4. As old as my pond was losing a couple of inches of muck a year was a must! I now have lost close to 5 to 8 inches and that's a LOT spread over a 1 acre pond!
5. Here in the south it gets soooo hot my 1 acre pond can get real warm and mixing that water to keep things stable is a must for me I think.
6 Your air acts as a large filter for your pond just like in an aquarium if you will. It helps keep things cleaner!
Hope this helps!
