Product Information

Alfagrog is a very porous biological filter media that has a large surface area for bacteria to congregate in. As a Swell own brand you can increase the quality of life in your aquarium at a cheaper price than most other brands, whilst still getting the same rich, high quality material.

  • Approx Weight 13.5 kg
  • Approx 1 Cubic foot in volume.

Alfagrog is ideal for use in any biological filter system. It is very popular among koi keepers and commonly used in multi chamber filter systems.

Replacing plastic filter media with Alfagrog will massively increase the biological capacity of your filter.
