"Exxodus-bac Brick" is an extremely porous filtration Brick that encourages bio-filtration and bacterial colonization in aquariums and aquatic systems.

  • Designed to be used in marine and freshwater aquariums with a pH of 7. 5 or over. Highest porosity and largest useable surface area, per unit weight or volume, of all filtration media available.
  • Provides large amounts of anaerobic surface area for bacterial colonization for denitrification, and sulfur doping to act as an electron donor to accelerate the process in freshwater, ponds or marine applications. Provides over 71, 000 square feet (6, 596 square meters) of surface area per liter of medium; one brick has about 125, 000 square feet of useable surface area for bacterial colonization.
  • Reduces phosphate and dissolved organics. Doped with Aragonite to buffer pH, preventing acid buildup which eventually would kill healthy organisms and reduce capacity.
  • Stays wet for days, allowing bacteria to remain viable after an equipment failure and ready for the repair.
  • Made in the USA.
