ExxodusNitryx is an extremely porous filtration medium designed to be used in all aquariums and aquatic systems for bio-filtration. It literally has the highest surface area of any filtration medium in the world, by far, yet it provides excellent flow characteristics! Each liter of ExxodusNitryx provides over 71,000 square feet of surface area internally for bacterial colonization, providing for nitrification (if employed aerobically) and vast amounts of anaerobic or anoxic surface area to foster denitrification, as well. One brick provides about 100,000 square feet of useable surface area for bacterial colonization. In addition, ExxodusNitryx is unique in that it is doped with sulfur particles which act as an electron donor for the cultivation of large amounts of anaerobic microbes to provide for a huge denitration capacity - much larger than any other known material. It may be used as your primary or only bacterial denitration medium. It works extremely well in nano aquariums, as well as systems of all sizes. It is particularly well suited to reef systems with live rock including FOWLR systems and will not foster problems that alcohol denitrators may. Use in a canister filter, reactor, or other type of aquarium filter with SLOW water flow. Primarily designed to be submerged to foster anaerobic or anoxic conditions, but may be employed in a drip system for more nitrification.
