Product Information

DENIBALLS are a filter material and bacterium food for the Nitratereductor, made from a special biologically based plastic material. Bacterial colonies will grow on the surface area which will provide biological filtration within the unit.

This material is consumed by the oxygen free bacteria that forms in the chamber, this bacteria reduces the nitrates in the water to nitrogen gas.

For the Aqua Medic Nitrate Reductor 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.
