A supplied membrane bag is filled with nitrate-reducing carbon source 'nitrate fluid' and installed inside the reactor as a slow-release system.

This nitrate filter uses alcohol to fuel the bacteria that convert nitrate to nitrogen gas via a reduction process. Like all nitrate filters, there is a period of seeding and creating an anoxic environment within the reactor, which can take some time, however, once established the filters are very robust and efficient in their ability to remove nitrate from the water.

David Saxby spent great amounts of time and effort working with Deltec in Germany to create a new range of nitrate filters which would overcome many of the problems that are commonly found with this kind of reactor.

The nitrates in his 3,700-gallon aquarium had crept up to the 50-60 ppm level due mostly to the 400+ fish that the tank houses and was having an effect on the bright colours of some of the corals. Working with the aim to make the new nitrate filter as simple and effective as possible it took about 10-12 weeks to bring the nitrate in his complete system to zero and involved many adaptations to the reactor.

The new units are alcohol-fed, which can be added by syringe, osmotic bag or by a peristaltic pump and are capable of being pressurised so that they can sit in a cabinet below the tank if you do not have a sump.
