product highlights

The Fluval BioMax provides an optimal environment for the colonization and growth of beneficial bacteria. The unique bio rings have a complex pore system that provides an optimal environment where beneficial bacteria can thrive. Fluval BioMax also reduces and controls ammonia and nitrate.

Features:

  • Suitable for freshwater, marine or reptile environments
  • For the Fluval U2, U3, U4 Underwater Filters

    Includes: Bio Media, 170 g (6 oz)
    Intended Pet(s): Fish
    Compatible With: Fluval U2, U3, U4 Underwater Filters
    Advice for Use: NEVER use tap water to clean filter media as this will kill the beneficial bacteria that helps keep your water healthy. Rinse in a bucket with water taken from your aquarium. To ensure constant presence of beneficial bacteria, do not replace all filtration media at the same time. For best results, replace 1/2 quantity of BioMax nodes every 5-6 months.
    Caution: NEVER use soap or detergents, as traces of cleaning products will harm aquatic life.
