The filtration system is of key importance in keeping your Koi pond water crystal-clear and free of chemical pollutants. There are three types of Pond Filtration:
- Biological Pond Filtration
- Mechanical Pond Filtration
- Chemical Pond Filtration
Mechanical Pond Filtration: Refers to the physical removal of debris from water by materials that trap large and small particles.
Chemical Pond Filtration: Removes pesticides, colors, odors, organic waste, excess nutrients and other harmful chemicals from your pond. Ultraviolet Clarifiers, carbon and zeolite are examples of products to be used in your filter for chemical filtration.
Biological Pond Filtration: This is where your pond filter provides a place for beneficial bacteria to grow on special media. These bacteria remove harmful dissolved pollutants and nutrients from pond water. Known as the "Biological Filter" these beneficial bacteria convert poisonous compounds such as ammonia and nitrite, into less toxic nitrate. The end by-product, nitrate, is used as a food source by aquatic plants. This continuous process is called the nitrogen cycle.
