ESV Granular Activated Carbon 3.5 lb.

ESV Granular Activated Carbon 3.5 lb.
Granular Activated Carbon based on bituminous coal provides the best combination of pore size, large particle size, high surface area, low ash, and hardness for chemically filtering aquarium water. In addition, test results confirm no leaching of phosphate. The high hardness level of this carbon prevents the dispersion of particles throughout the aquarium, which can occur with softer grades of carbon. This carbon meets American Water Works Association and Food Chemical CODEX requirements.
