Pond Filtration

Why Are Pond Filters Important: Pond filters are essential for keeping the water in your backyard pond healthy and crystal clear. When waste from fish breaks down, it releases harmful chemicals like ammonia and nitrites. Not only is a fish’s waste harmful; but decomposing leaves, dirt, and debris that fall into your pond also introduce dangers. By removing all the harmful chemicals from the water, filters the longevity of all your fish.

Bio Filter: Bio-filters work by culturing beneficial, natural bacteria in your pond with biological filter media. Since these colonies of bacteria are naturally occurring, this is an appealing choice for anyone who wants to make their pond as organic as possible. Keep in mind, the bacteria that grow in your bio-filter need a constant supply of water to stay alive, so expect to run your filter pump year-round.

Mechanical Filter: Mechanical filters work by trapping dirt and debris to make your water clear. The pump pushes unfiltered pond water in one end and runs it through stacks of mechanical filter media arranged from coarse to fine thickness. Along the way, the media catches larger debris first and the smallest particles last. Another benefit of mechanical filters is that they are relatively easy to clean, but need to be cleaned frequently to rinse out debris.

Choosing The Best Pond Filter: The first thing when choosing the best filter for your pond is to determine the size of your pond. Choose an appropriate filter that is rated for how many gallons of water your pond holds. Next, determine how densely populated your pond is. If you have a balanced pond with at least 50% plant coverage, then you can buy a filter without a UV sterilizer, since the plants also help clean the water. Choosing between a mechanical and biofilter is down to personal preference, however, we do recommend purchasing a mechanical filter if your pond has a lot of debris.
