Aqua Medic Deniballs are great for fresh and salt water aquaria to help reduce nitrates. Available from Swell UK.
A filter material and bacterium food for the Nitratereductor is available from Swell UK.
DENIBALLS are made from a special biologically based plastic material.
In the absence of oxygen, anaerobic bacteria metabolize this material.
The bacteria are used for the reduction of nitrates - reducing nitrate to nitrogen gas.
For the NITRATREDYCTOR 5000, about 5 litres (1.3 gallons) are required. Changing the DENIBALLS after approximately 12 months is recommended to ensure safe and maintenance free denitrification in fresh and salt water aquarium.
