As aquarists, we are all aware of the need for biological filtration and most of us also understand the principles involved as well. Waterfalls

When I first started my pond two years ago, the only aeration/moving water was from a small fountain and sprinkler head with an attached foam filter sitting in the middle. Although this was adequate to keep the fish alive and the pond from turning into a scummy slough, I would have preferred something that looked a little more natural. Next year I had a waterfall.
