Exxodus BAC 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 Exxodus BAC provides over 26,000 square feet of surface area internally for bacterial colonization, providing for nitrification and vast amounts of anaerobic or anoxic surface area to foster denitrification, as well.
Exxodus BAC will reduce the levels of toxic ammonia, nitrites and nitrates, as well as phosphates and organic pollutants in all aquaria.
It may be used as your primary or only bacterial filtration 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 bio balls may.
Use in a canister filter, reactor, or other type of aquarium filter with good water flow. Works well submerged or in a drip system.
