In a natural pond the water soil plants and animals all live in harmony.
Natural filtration systems for ponds.
I ll deal with esthetics in a future post on how to build ponds.
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.
A natural filter need only be 10 of the pond surface area to be effective.
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.
No one comes along to clean the pond or to aerate it.
10 to 30 percent of the pond surface should make up the bog.
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.
By absorbing nutrients and covering a large amount of surface water plants will compete with nuisance algae and help prevent weeds growing uncontrolled.
Biological filters which combine mechanical and bacterial filtration help.
Keeping even the smallest ponds clear and free of algae can be challenging.
Directions for creating a partition bog gravel filter follow the usual directions for building a liner pond.
