Bacteria King Bio Media

Bacteria King is an ultra lightweight bio media that is extremely porous to enhance the growth and colonisation of nitrifying bacteria.

Its extremely porous structure ensures that fast and efficient biological filtration takes place in your aquarium, and helps to clarify aquarium water quickly and naturally.

Bacteria King has up to 400 times of decomposition rate, which means it breaks down ammonia and nitrite very quickly and prevents nitrogeneous wastes from reaching harmful levels in the aquarium.


The benefits of Bacteria King:

  • Inert, non-toxic, safe for aquarium use
  • Highly porous media
  • Large surface area for bacterial colonisation
  • Removes ammonia and nitrite by bio filtration
  • Does not alter water pH or mineral balance
  • Can work even in small bio filters due to high surface area of each piece of media
  • Clarifies and revitalises aquarium water


Bacteria King is a suitable bio media for the following applications:

  • Freshwater Aquarium
  • Marine Reef Tank
  • Koi Ponds
