Alfagrog – Biological Filter Media
Alfagrog – Biological Filter Media –
A porous foamed ceramic material, which is lightweight, strong and inert.
It’s high surface area makes it the natural choice for colonisation by micro organisms in biological filtration systems, resulting in cleaner water.
Benefits of Alfagrog over other filter media:
- Extremely high surface area
- Highly porous
- Inert, pH neutral
- Available worldwide
Selected clays and raw materials are rapidly sintered at high temperature. This is to produce a foamed ceramic porous mass, which is crushed and sieved to a convenient particle size.
