Pond Filters

Why Ponds Need Pond Filters?

Since ponds aren’t naturally aerated, debris from plants and fish waste can lower the level of oxygen in the water. This lack of oxygen can cause both the fish and the plants to die. Pond filters are designed to solve this problem, cleaning the pond and providing a breath of fresh air for the pond habitants. Pond filters might not be needed for ponds that only have a few fish. However, if there are a lot of fish in the pond, a pond filter will help to keep the water conditions livable.

Pond filters are designed to do a number of tasks that help to clean the water. They break up dangerous fish waste into smaller pieces that wouldn’t otherwise decompose. Pond filters also help to remove dissolved waste from the water, purifying the water from these potential toxins.  Algae growth is a problem in ponds because the waste from the fast spreading plant depletes oxygen in the pond. Pond filters remove the nutrients that algae needs in order to live, reducing the amount of algae that can grow in the pond.

The kind of filter that is used depends on the size of the pond and how much plant and fish live in the pond. One or more filters can be used in conjunction with each other for larger ponds. A mechanical filter can be used to protect the pump by separating large particles from the water. A skimmer keeps debris from falling into the pond water. Biological filters are used to remove toxins released from fish and plants.

Filters can be used even if a pond is purely ornamental. It might not work to keep the water 100% clear, but it will keep large particles and debris from falling into the water and clogging up the pump.
