Pond Boss Forums AERATION Systems questions waterfall question

Dave - It depends on the amount of water the pump moves as well as the distance it will be moving it, but I tend to go about twice the size of what the pump's outlet pipe is when doing runs between 12 and 16 feet or so. Also, design the system so you have as few turns/corners in the pipe as possible.

To maximize the "look" and sound of lots of water, you'll want to do very level ledges, not a variable cobble type fall (see rockytopper's pic above and note how it is a series of ledges). It's not really a single waterfall, but rather a series of very small waterfalls, one after the other.
