Brightwell Aquatics Xport NO3 Brick
Overview
Brightwell Aquatics Xport NO3 Brick is an ultra-activated denitrification brick engineered to provide enormous anaerobic surface area for nitrate reduction in marine, reef, pond, and hard freshwater aquariums. Doped with elemental sulfur and aragonite, it supports powerful bacterial denitrification while buffering pH at the bacteria surface, helping maintain long-term water quality and stability in high-bioload systems.
Key Features
-
Ultra-porous ceramic brick with massive internal surface area for denitrifying bacteria
-
Doped with elemental sulfur to act as an electron donor, accelerating biological nitrate reduction
-
Designed specifically for denitrification (NO3 reduction) in marine, reef, pond, and hard freshwater systems
-
Also helps reduce phosphate and dissolved organics, improving overall water clarity and quality
-
Aragonite-doped structure helps buffer pH at the bacteria level, preventing localized acid buildup that can kill colonies
-
So porous it will wick water and stay wet for days, helping bacteria survive temporary power or flow outages
-
Ideal for use in sumps, large filter chambers, or dedicated denitrification zones
-
Works especially well when seeded with bacterial cultures such as MicroBacter7, MicroBacter Clean, or MicroBacter Start
