Alfagrog Ceramic Biological Filter Media

Improve the biological performance of your filtration system with Alfagrog Ceramic Filter Media. Manufactured from highly porous foamed ceramic, Alfagrog provides an exceptionally large surface area for beneficial bacteria to colonise, helping support efficient biological filtration in ponds and aquariums.

The open, porous structure encourages the growth of nitrifying bacteria that naturally break down organic waste, helping maintain cleaner, healthier water. Its lightweight yet durable construction allows excellent water flow throughout the filter while providing long-lasting filtration performance.

Unlike many alternative filter media, Alfagrog is chemically inert and pH neutral, making it suitable for freshwater aquariums, marine aquariums and pond filtration systems. The irregular 10–45mm pieces create excellent water circulation and maximise the available surface area for biological filtration.

Whether you're building a new filter or upgrading an existing system, Alfagrog offers a reliable, economical and effective solution for maintaining healthy water quality.
