My well water drops about 2 feet to the pond so I assume the splash and the force of the water hitting creates some sort of oxygen.. Or is that way to small to make a difference?
I think you are looking for water surface contact with the air. Mixing in bubbles is not really adding the air. I think the more you can have the water become in contact with the air the more O2 you will end up in the water.
See I thought with these air stations it was just like an aquarium and the station was adding air to the water from the bubbles. But that is not really the case even in the aquarium. The case is that your moving the water to the surface where it can take in the O2 more then the bubbles contact with the water.
A lazy river into the pond from a water source would be a great idea. I do not know for sure but I do feel adding our cool water to fill our pond over our water fall triggers something in our common shiners and emerald shiners to populate like crazy.
Cheers Don.
