Pond Filters and Types

Pond-filters.net provides reliable information about the many types of pond filters, including intake, submersed, in-line, external, and combination pond filters. The respective advantages and disadvantages of pond filters as well as general pond care and maintenance are topics which are also covered by this site.

Pond filters, also known as biofilters, are an important part of pond care which provide for many different aspects of a pond’s needs. These include breaking down the waste of the fish, which can be dangerous. They remove dissolved wastes from the water, as well as certain particles. By removing many nutrients which algae survive on, they discourage its growth. Much of this serves to protect the pond pump from debris.

Different types of pond filters are used for different reasons. The first step in successfully maintaining a pond is to become acquainted with the right filter for the particular pond.

Intake filters are very small and only suitable for preventing damage to the pond pump. They are not ideal for thorough waste removal. However, they are inexpensive, easy to clean, and can often create fountains and waterfalls.

On the other hand, submersed filters are generally larger and more versatile. Along with protecting the pump, these filters also aid in maintaining water quality. Cleaning does not have to take place as often as with an intake filter. While an intake filter often needs to be rinsed daily, a submersed filter may go days to weeks without being cleaned. This pump also may have fountain or waterfall attachments added.

An in-line filter may operate in either an above-ground or submerged fashion. These are sealed canisters which operate under pressure. In-line filters may be filled with chemical, mechanical, or biological filtration media.
External pond filters tend to be the largest of pond filters. These are located above ground, somewhere near the pond itself. Some versions may be buried as well. These may work with a variety of media. However, they usually work with large foam sheets for mechanical infiltration. Several gallons of plastic or porous biological media may be located underneath.
It may be days to weeks, even to months, before an external pond filter needs to be cleaned. The biological filtration is very efficient and for that reason can support the largest quantity of fish. Of course, the above ground infiltration means that this unit is especially easy to clean. These may be less of an aesthetic choice, however, because the size and above water location will make them difficult to hide. Also, water leaving the filter is unideal for waterfall creation.
As different filter types have different strengths and weaknesses, many people find it advantageous to use a couple pond filters in combination.
For a large pond with larger fish, an adequate pond filter option is crucial to ensure that the fish stay healthy. It is also important to avoid the spread of bacteria and disease.
A pond filter works ideally in combination with other pond equipment. A UV sterilizer is another important appliance for pond maintenance. A UV clarifier or simply a UVC are alternate names for this device. Finally, a pond pump is also a crucial item when it comes to pond care.
