exxodus•nitryx
unique ceramic filtration medium providing highest possible surface area and doped with sulfur for denitrification in ponds, reefs and planted aquariums with a pH of 7.5 or greater
The Continuum advantage
Exxodus•Nitryx is an extremely porous filtration medium designed to be used in all aquariums and aquatic systems with a pH of 7.5 or greater, 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•Nitryx provides over 40,000 square feet of surface area internally for bacterial colonization, providing for nitrification (if employed aerobically) and vast amounts of anaerobic or anoxic surface area for denitrification.

Keith Gibson –
Installed Exodus•Nitryx in my planted tank with a pH of 8.0. The water clarity improved noticeably within a week. The filter runs smoothly and the tank has maintained stable ammonia and nitrite levels. Great surface area for beneficial bacteria to colonize.
Edward Abraham –
Used it in a reef tank with stable pH. The denitrification helped reduce nitrate buildup. Flow is consistent and the ceramic media doesn’t clog easily. Works well with my existing filtration system.
Emma Hunter –
Felt like a significant upgrade from my previous filter media. The surface area is impressive and the sulfur doping helps with nitrate reduction. A bit more expensive, but worth it for long-term stability.
