Excellent idea Rainman. We're in synch on this. In our case the bog is after the main pond, so we're hoping to pump from the outlet of the bog to the the top of the stream/falls, and into pond from there. Good call on the diffuser as well. Did I read somewhere that these need to be moved around depending on the season? If I'm cycling 6500 gph through pond, would this be enough movement?
