Natural ponds do not need a pond filter, since Mother Nature takes care of all of that. However, in order to keep a pure and healthy manufactured pond, the pond must have a solid filtering system. Pond filters prevent the water from becoming cloudy so that you can gaze at your fish. A pond without filter systems installed can become filthy and toxic to your fish. The small, physical, rotting substances within the water cause it to become filthy and very unpleasant to smell.
Pond filters do take some upkeep but they are worth having in your pond. It is debatable by some as whether to use pond filters in their ponds, it is a personal option of course. Having a filter depends on whether you plan to have fish, the types of fish and number of plants as well as the size of the pond. If you neglect to add a pond filter to your manufactured pond, you can expect the pond to become green, cloudy from muck and green algae. This is not how you want your lovely garden pond to turn out.
Pond filters are made of a variety materials such as polyester knit type materials, bio balls or even sponge like materials. Pond filters allow you to have a constant flow of pure cleaner water by catching and growing solid bacteria, which aids in keeping a proper pH balance. Keep in mind the larger the area that catches and grows these solid bacteria the greater your pond will be. To promote a well functioning balance in the eco-system of your pond water, pond pumps are required.
Depending on the model, size and other bells and whistles, you can expect a filter system for your pond to run from $40 and on up. Your option will depend on the size and volume of the pond, the type and number of fish and plant life as well as your budget. It is best to err on the side of the pool filter rating being higher than the size of your pond rather than to buy one which is too small and will not be enough for your filtering needs. You can choose from submersible or external pond filters.
Submersible Filters
Submersible pond filters are highly versatile, as there are so many different filtration modes. These modes include mechanical, chemical or biological. They are great for cleaning a pond and are useful in other ways as a water-filtering element, such as a water fountain. The drawback of submersible filters is that you may have to get into the water to clean them.
External Filters
These are the largest type of pond filters and they support the big numbers of fish. They rest beside the pond and are much easier to maintain. However, they are let down by their visibility and size, although some strategically placed pond plants work as a excellent camouflage.
