Pond Biological Filter Media

Biological media works by using its surface area to produce and house bacterial colonies that feed off nitrates and phosphates, both pollutants that can cause algae and other water problems.

The media also filters out tiny particles of dirt and grime to improve the clarity of the water in your pond. The media often takes the form of ceramic, plastic or sponge materials that create a porous surface-great for bacteria to grow. This is a great, natural way to cleanse your pond of unwanted nasties and pollutants.

When cleansing biological media, always wash in pond water, this will retain the essential bacteria.

We have a large range in stock, from expert brands such as Evolution Aqua and of course our own branded Swell range, which is of the same fantastic quality and at an even better price.
