Brilliant. I'm following now. Why don't they teach this kind of stuff in school?!?!
Since my pond is shallow, 2' of water, is there a reasonable limit to which you would be able to pump up? I assume the venturi's ability to pick up solids lessens with more head... or maybe not? Also with such a shallow area would the introduction of air in addition to the pumped water have an affect? I'm assuming that the air needs to be introduced below the water line to achieve it's affect? (But again maybe not!)
