Filtration is the process by which your pond is cleaned of impurities. Once the water reaches the filter it usually passes through three key stages: 1 UVC Radiation If your filter has a built-in UV unit this exposes the water to UVC rays which cause microscopic single cell algae to flocculate (that is to stick together to form larger pieces). This action causes this suspended algae to die and fall to the bottom of the pond. This clears the water and the solid particles are sucked up by the pond pump. 2 Mechanical Filtration Dirt such as fish waste and algae particles generated by UVC radiation are caught in physical mechanical barriers. Foams are a typical example - often with multiple grades to catch even the smallest pieces. 3 Biological Filtration Dirt-free water then passes through a bed of bio-media. This material will often have a multi-surface appearance for healthy bacteria to stick to and thrive. Such bacteria break down ammonia into Nitrite. Nitrite is broken down into nitrate. Main types of pond filters available: The traditional ‘Box’ filter sits pondside or at the top of a waterfall. Pond water is pushed into one end and returns via gravity from the other. These filters are generally larger and provide a massive area of filtration media to cope with larger ponds. A more modern approach is to house the filter media into an airtight cannister. The water enters the filter under pressure and leaves it under pressure allowing the filter to be hidden. Great for smaller ponds - these filters provide maximum landscaping opportunities.
