Establish a healthy ecosystem for your fresh or saltwater aquarium with API Bio-Chem Stars Filtration Media for Biological Filter. This biological filter media, named for its unique star shape, provides a home for growing massive colonies of nitrifying bacteria that convert harmful ammonia into nitrate. This nitrogen cycle occurs naturally in all underwater environments. Formed under a patented production process, API Bio-Chem Stars Filtration Media for Biological Filter has a 50-70 micron internal pore network that provides four times more surface area for bacteria colonies than ceramic rings. Ideal for aquarium start-ups, it can also be used as part of your aquarium maintenance routine and will not break down or clog filters.

Key Benefits
  • Provides four times more surface area for colonization than ceramic rings.
  • Provides more growing area than plastic balls, foams or under gravel filters.
  • Advanced polymer material has optimal pore size for maximum oxygen and water transfer.
  • Use when starting or maintaining aquarium as part of the nitrogen cycle process.
  • For use in fresh and saltwater tanks.
