Your Pond Filter Has an Important Role in Keeping Your Pond or Water Feature Clean and Clear Your Pond Filter Has an Important Role in Keeping Your Pond or Water Feature Clean and Clear

When a home owner starts the education process about how to build a backyard pond and waterfall is important to understand some of the basic science involved in developing and maintaining a healthy eco-system.

The filter a vital piece of the puzzle in helping you keep your pond water clean and clear. To aid you in the cleaning and maintaining of your pond or water feature you need the proper filter. This will save you time, and allow you to relax by your water garden instead of working on it or fighting with it to keep the water quality at an acceptable level. Some filters will require regular manual cleaning while others are fitted with an automatic back wash flush cycle that is virtually self cleaning. Some filters with back wash systems can be installed so that the back wash cycle will act as an irrigation system in nearby flower gardens.

There are several different pond filters available today.

Biological Filters
If you’re hoping to house your waterfall in the most natural environment possible, it’s a good idea to look into a biological filter. This filter uses healthy bacteria in the water to absorb ammonia, and turns harmful nitrites into helpful nitrates. These bacteria need a large surface area to live and they act as a natural filter system. The biological system has an intricate sponge-like filter media which is a hospitable environment for these hard-working, beneficial bacteria.


Mechanical Filters
Biological and mechanical filters, in essence, work together. Although you can use a biological filter on its own, it’s a good idea to trap the larger particles and sediments through the mechanical filters before allowing them to filter through the biological system. The mechanical filter consists of a box skimmer, a debris net, and a filter mat which catches the waste before it even enters the pump area. The mechanical filter catches all of the sediment but the tiniest particles which are cleaned up by the biological filters.

You can also find newer filters which contain a biological and mechanical filter system in one. These are known as pressure or gravity filters. They are quite convenient and growing in popularity. However, as convenient as this may be, some say that two separate filters is the more effective way to go. Other filter systems include vortex filters, sand filters, and U.V. filters. These are slightly less appealing to the naturalist, but once again, it largely depends on preference.

I recommend first time pond builders purchase a water garden pond kit as these kits come with equipment that is calibrated and designed to work together to create a healthy pond ecosystem. The filter provided is designed to properly filter the correct volume of water as indicated on the kit box. It is a great idea to understand the function and operation of your filter, however if it purchased with a kit you do not have to worry about purchasing the wrong filter for your application.

For pond owners who are experienced and familiar with water gardening you may want to do some customization and incorporate some additional filtration for a variety of reasons. In this case, it is important to understand what you are expecting from your pond filter and then take the time to educate yourself regarding your options and which filters will fit your application best.
