fluval biomax's unique manufacturing process provides enorjmous surface area with appropriate pore and tunnel dimensions to support various essential bacteria. Micro-tunnels comprise 85% of the "fluval Biomax" pore volume, providing oxygen to nitrifying bacteria, ensuring rapid removal of toxic ammonia and nitrite. Micro-Cavities account for 15% of the internal pore volume, providing habitat for other species of bacteria, which require oxygen poor conditions to optimize water quality.
