Thanks for all the input; as with many questions there are no cut and dry answers. I'm installing a new system in a pond that is starting it's 4th year with warm-water fish (LMB/BG). Deepest spot is 10' with an average of 5' over about a 3/4 acre pond. Plan is to place one diffuser in the 10' area and one 150' away into the shallower end. I'll do this in March when the water temps start to change over. Pump capacity is 3-4.5 CFM at 30 PSI - depth of my pond no issue here. Does anybody see any issues with going directly on the bottom with the diffusers and letting the windmill system run full-time (wind alloeing) - as I am not near the pond - No suplemental feeding is in place.

Thanks
Joe
