There are many filtration options for modern Koi ponds. In fact selecting which is best for you is one of the biggest challenges simply because there is so much choice.

Most successful Koi filtration systems consist of two primary stages: Mechanical & Biological. While these functions are completely separate, it’s important that your choices are compatible and that they work together effectively as a filtration system – system being the operative word!

Mechanical Filtration: Is the physical process designed to remove physical organic material.

Biological Filtration: Is the chemical process designed to facilitate the conversion of harmful waste chemicals produced by our Koi into essentially harmless chemicals.
