Jim set up our berm to have the water go over four falls before running down an 8 foot stream into the pond. He saw that as getting pretty near full oxygenation. Phyllis Hiya Phyllis, There was an article, but now I can't remember whether it was in a magazine or on the web regarding this, with stats. What I remember from it was that water falling on rocks got the highest score, then fountains, then airstones... I believe. I'm only positive about the water falling on rocks. ~ jan ------------ Zone 7a, SE Washington State Ponds: www.jjspond.us |
