Pond pump pre-filters act as a mechanical filtrater to prevent leaves and other large debris from entering your pump. They save you time while also preventing excessive wear and tear on your pump. Pond pre filters also increase the biological filtering ability of your pump dramatically using a special type of foam. The foam or filter sponge helps to create a large surface area for beneficail bacteria to grow on, which increases the biological filtration of your pond.
Our pond pre filters are suitable for use with ponds, aquariums and aquaponics systems and can be used on both pond and fountain pumps.
