AH thats the part I missed, The part about it being well water, I am interested in the circulating process of the pond, I think my bottom diffuser is lifting ok, I just want to make a surface skimmer that concentrates my surface trash using 1/2 pvc and swim noodles postioned so that the leaves and stuff are trapped for easy removal. With my pond being in the timber every little bit I can get out before it sinks will help. I may look into a submersible pump and put a nozzle on it to see what type of flow I can get out of it
