Garden Pond Filters

Welcome to the 43 new Subscribers.

Do you know the benefits of having a Garden Pond Filter?

Besides removing solid debris from the pond, a filter matures to provide a supportive environment for beneficial bacteria that break down soluble waste. A filter also provides oxygen for your pond, fish in poorly oxygenated water will become stressed and die.

Most first time Pond builders think filters are just for clean water to see your fish. Filters are so much more important than having clean water to see your fish.

Koi are large, active fish that produce large amounts of waste and use up lots of oxygen. Pond fish are just like any other animal in that they excrete waste that will be toxic if left to accumulate in their bodies. That is the function of a pond filter; to reduce the deadly ammonia from the waste your Koi produces. Ideally your pump and filter need to process the total volume of the pond at least once every two hours. Remember, do not switch off your filter for more than 12 hours or the oxygen-dependent nitrifying bacteria will start to die.

Garden Pond Filter Options

For a small garden pond an internal filter will sit inside of your pond. The internal filter will generally consist of large foam blocks that replace the pumps strainer. When first matured, this type of filter is undoubtedly very efficient, but it suffers from the inevitable drawback of area blocking caused by a build-up of heavy solid waste products and the formation of colonies of anaerobic bacteria.

External filters consist of an external chamber placed outside of the pond. Although external filtration systems are considerably more expensive to build and more complicated in their construction, they are far more effective and maintainable. Draining debris is simple and analyzing water quality and condition is effortless. External filters fall into two main groups, those which are pump fed and those fed by gravity.

Pump-fed single-chamber filter units are the most widely used. They can be installed in minutes, even on an existing pond. There are easy to find in commercial pond shops, even for a large 2,000 gallon pond.

Gravity-fed multichamber filters are constructed or installed at the same physical level as the pond so that the water level in both is identical. Therefore, if water is drawn from one end of the filter, gravity carries a fresh supply to the filter. Irrespective of how many chambers are used, water will flow from chamber to chamber, passing through successive blocks of media as it progresses. Water is transferred from chamber to chamber via transfer ports, and these must be of sufficient size to ensure there is no restriction of flow. This is an excellent filter system but it is relatively expensive unless you can design your own.

Pressurized filters are totally sealed and can be buried, with the return consisting of tubing feeding directly into the pond or through a waterfall. This makes pressure filters sympathetic to the natural look. They are a small size, tend to block quickly, and need regular maintenance. They are suited to smaller ponds.

A Skimmer Filter is suitable for medium to large ponds up to 5,000 gallons. It is installed adjacent to the pond through the pond wall.

A Garden Pond Filter is the best filtration system you can have to keep Koi alive and healthy, unless you have a natural stream flowing through your yard.

Filtration Systems must be treated like the living entities they are. If they are not provided with oxygen, water, and food, they will deteriorate and die. For this reason, a bio filter must be run continuously, ensuring that the bacteria are provided with the materials for life.
