-Different Types of Garden Pond Filters

Pond Skimmers
Skimmers are garden pond filters, also known as mechanical filters that require some type of screen, basket, or net to trap waste. Skimmers are normally installed around the surface of a garden-pond and drags in the top-layer of water, filtering-out floating waste like grass, sticks, and leaves. Skimmers are vital for preventing free flowing debris from ultimately plummeting to the floor of a garden-pond and putrefying. The amount of debris floating within a pond will establish how frequently the filter will be detached-from the skimmer to get rid of debris.

Biological Filters
Biological filters consist of useful bacteria inside the actual filter that sanitizes the pond water at a molecular level. In order to decompose ammonia within the fish-excrement, a biological-filter will be required. Biological filters metamorphoses destructive ammonia into nitrates, that then turns into a form of food for vegetation inside the pond.


Mechanical filters with a pond skimmer are quite efficient; however, it must be installed on the exterior of the garden-pond because it can occupy such a wide area. Therefore it is best suited for large garden-ponds. Many people prefer a combination of mechanical and biological filters. The best thing to do is to consider where you have space to install your garden pond filter and how you want the outcome to appear.
