How to Make a Natural Pond Filter With Sand & Gravel
Making a natural pond filter with sand and gravel is an environmentally friendly way to keep pond water fresh. This is important whether the pond contains fish or not; without a filtration system, the water will become stagnant. Garden ponds are a common yard decoration that contain small decorative plants and often ornamental fish. In addition many ponds also contain rocks, fountains, streams and waterfalls. A natural pond filter will go a long way toward keeping a pond fresh and aesthetically pleasing. Does this Spark an idea?
