Alfagrog is 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
- Lightweight
- Economical
The Alfagrog range of porous ceramic filter media is made under controlled conditions in Staffordshire, UK.
Selected clays and raw materials are rapidly sintered at high temperature to produce a foamed ceramic porous mass, which is crushed and sieved to a convenient particle size.
Alfagrog is available in a wide range of sizes giving the end user optimum media surface area in varying water flow rates.
The manufacturing process ensures that no substances are present to adversely affect the health of fish or plants. The material is pH neutral and can be used in both freshwater and marine applications.
Sold in pre sized amounts to fit 1 tier of our filter range. So to fill a shower completely you will require 3.
