We carry a wide variety of replacement filter
media for your Koi pond.

Bacteria convert harmful by-products from aquatic
animals into less harmful nitrates.  This process
occurs naturally in nature's lakes and streams.  In
a Koi pond these bacteria are found on the walls of
our ponds. They also can be found on the inside
walls of the pond plumbing, attached to the
skimmer basket, and on the rocks that form a
waterfall.

The reason it is important to consider what filter
media to use when we build biological filter
systems, is to increase the available surface area
for these bacteria to colonize. The important
consideration is to keep the pollutants and
unwanted debris out of our ponds, while keeping
the beneficial bacteria in our systems.

If you have any questions regarding the proper
media, feel free to contact us for help.
