Advanced Nitrate Removal Media
Designed to effectively reduce nitrate levels, this specialised filtration media supports the final stage of the nitrogen cycle within both freshwater and marine aquariums. By encouraging the growth of anaerobic bacteria, it helps convert accumulated nitrate into nitrogen gas, which is safely released from the system.
 
Promotes Anaerobic Bacterial Growth
Using proprietary treatment technology, the nano-ceramic beads within each block are specifically engineered to establish and sustain anaerobic heterotrophic bacteria in low-oxygen (anoxic) environments.
 
These bacteria — including species such as Paracoccus denitrificans and various Pseudomonads — carry out the process of denitrification, breaking nitrate down into harmless nitrogen gas and effectively exporting excess nutrients from the aquarium.
 
Completes the Nitrogen Cycle
While aerobic bacteria convert ammonia to nitrite and then nitrate, this media supports the crucial final stage of the cycle. Through denitrification, nitrate is reduced and removed, helping maintain improved water quality and long-term system stability.
 
Installation & Usage
Place directly into the sump.
Stack two Anaerobic Blocks horizontally.
Position a Denitrification Catalyst between the two blocks as illustrated in the product guide .The Denitrification Catalyst will gradually dissolve during operation and should be replaced approximately every two months to maintain effectiveness.
 
Capacity & Compatibility
Suitable for: Freshwater and marine aquariums
Treatment Capacity: 2 blocks treat up to 1,000 litres (264 gallons)
 
By combining advanced nano-ceramic construction with proprietary bacterial cultivation technology, these Anaerobic Blocks provide a targeted and efficient solution for long-term nitrate control in modern aquarium systems.
