Collection: Filter media

For a pond filter system to function properly and for the pond water to be cleaned, the right filter media are required. If the correct filter media are used, the biological balance in the garden pond can be regulated or positively influenced, and pollutants can be filtered out of the pond water. Through appropriate filter media, such as Bioblocks, Bio+ or Biomedium, pollutants are biologically broken down and excreted. Biological filtration plays an important role in fish and koi ponds, thus creating an optimal living environment for your pond inhabitants.
