Which Pond Filter?

Choosing the right pond filter does not have to be a difficult decision. Often the choice is governed by what you want to use your pond for i.e. keeping fish or creating a water garden. To begin you pond filter selection you first need to narrow down the wealth of pond filters available to you by answering some simple questions.

Firstly, how big is your pond? By measuring the volume of your pond you will immediately start to exclude some of the small pond filters or heavy duty pond filters.

Where will your pond be situated? Will you be able to access your pond filter easily? Answering this question will help you decided whether an internal or external pond filter will be best for you.

If, for example, your pond is snuggly fitted into your garden design then you may want to opt for an internal filter. This will sit within your pond and use a small pump and an inlet to cycle the water through its filtration system.

If, on the other hand, your pond is centrally located with easy access to all sides than an external filter may be best. These efficient pond filters sits just above water level and removes toxins and contaminates. For larger ponds these external filters are ideal as they are the most efficient filtration systems available; especially when coupled with a U.V. steriliser. To avoid these filters being easily seen they can commonly be secreted in amongst a water rockery or dense foliage. If opting for an external pond filter then you will need to make a further selection of either a biological filter or a pressure filter.

Another consideration when choosing a pond filter is maintenance. Different filters will require different levels of maintenance to ensure optimal performance throughout the year. Biological filters, for example, need to be run constantly throughout the summer season (March – October). In October/November the filters can then be disconnected and cleaned before being reinstated in time for March of the following year.

Pond filters used for water gardens typically have to be maintained less than those used for fish ponds, for example, especially if expensive fish such as Koi are being kept in the pond.

When buying a filter for a fish pond it is always a good idea to ask the friendly staff on hand as although the above rules serve as a rule-of-thumb, individual circumstances can dictate that one pond filter is preferable over another.
