Natural filtration systems for ponds.

The use of the word natural here refers to the pond filtration system not the esthetic look of the pond. I ll deal with esthetics in a future post on how to build ponds. In a natural pond the water soil plants and animals all live in harmony. Natural garden pond design in a conventional backyard pond design algae levels are controlled by adding chemicals and using a mechanical filter and a circulating pump that cost up to several.

Plants provide a means of natural water filtration absorbing excess nutrients oxygenating water and removing harmful substances. Pottery bog filters are great for small ponds or additional filtration for larger ponds. Size is determined by pond surface. No one comes along to clean the pond or to aerate it.

Biological filters which combine mechanical and bacterial filtration help. Directions for creating a partition bog gravel filter follow the usual directions for building a liner pond. The movement of water across plant roots in a natural filter encourages increased nutrient consumption leaving less nutrients available for pea soup algae to thrive. A natural filter need only be 10 of the pond surface area to be effective.

But introducing water plants and scavengers such as water snails and tadpoles into a pond is an easier and less expensive solution.
