When I was going through this discussion with Bill he said to have a look at the rocks. As soon as I did this I could tell we were at a very high level of air in the pond water. I was told another good indication is to take a glass of the water and let it sit over night and see how many bubbles are in it.

There are so many factors like alga, plants, water temp, and number of fish or how active the fish are.
