2 L format is designed for use with smaller canisters and power filtration
Deep pore structure with interconnected micro-tunnels offers vast surface area for billions of beneficial nitrifying bacteria to establish and thrive
Linked cavities permit free and even water flow, discourage blockages and prolong contact time for superior and effective biological filtration
Allows for the establishment of a high concentration of nitrifying bacteria to reduce ammonia and nitrite quickly and efficiently for a healthier aquarium
For best results, rinse monthly using aquarium water and replace partially every 6 months
For optimal filtration, place in the last stage of the filtration process
Usage: For most aquariums, 1 filter basket layer of BIO-FX is adequate. For higher bio loads, additional BIO-FX can be used
