The rate of water flow through the biofilter will have a major effect on its results. A fast water flow will not allow the bacteria to clean the water completely and may even dislodge the bacteria from the media. Care should be taken when cleaning a biofilter. Mechanical elements should be rinsed in a separate container of pond water. The biomedia should not be disturbed enabling the beneficial bacteria to remain.
Filter designs differ depending on planned placement.
Some small filters are designed for underwater use, usually near the submersible pump. Other filters are designed for in-ground use, however, the lid of the filter should be above ground for easy access, yet the filtration media is situated below water level, concealed underground. There are also those filters which are above-ground units. Selecting a filter for your pond based on pond volume alone is not enough.
