If a water feature you can assemble in a day is more your speed, this is the project for you. This fountain is designed around a stone from which the water will flow out of into a gravel-filled reservoir below, and circulate back up through the rock with the help of a pump. You can either look for a rock, that comes pre-drilled, at local stone suppliers, or you can drill a hole through it yourself with a rotary hammer drill. Best of all, this water feature requires very little maintenance because it was designed to not require a collection pond. Locating it out of the sun reduces algae growth, keeping the water fresher.
