Starting: Before starting, the Nitratereductor is filled with aquarium water and controlled for
leaking and the right position of the sealing. Close both clamps tightly. The internal circulation
pump can be switched on.

Connection to an existing aquarium
If a Nitratereductor is connected to an existing aquarium with a rather high nitrate level, the inflow
of aquarium water should not immediately be started. The bacterial growth is enhanced by the
addition of 1 tablet of Denimar per day. If after 8 - 10 days, the nitrite has disappeared from the
reductor - a residual concentration of nitrate is harmless - the water flow can be switched on.
Connection to a new aquarium
If connected to a new aquarium, the bacteria does not have to be fed within the first 4 weeks, as
the nitrate forming bacteria Nitrosomonas and Nitrobacter need this time to develop and to oxydize
the whole amount of ammonia and nitrite into nitrate.
Feeding: The feeding has to be adjusted according to the nitrate loading of the aquarium. It can
be controlled with a redox probe (see options). In a normal loaded tank, one tablet per day is
sufficient. It is possible to feed several tablets (up to 3 pcs.) at once. Then, the filter needs no
feeding for several days.
After some time, a slimy bacterial biomass is formed in the Nitratereductor. This a normal process.
A high bacteria population ensures a high removal rate of nitrate.

Feeding with Deniballs
The white Aqua Medic Deniballs are made of a biodegradable plastic material. This plastic material
is also produced biologically - the raw material is produced by bacteria. This new plastic material is
completely biodegradable. It can be used by denitrifying bacteria in the Nitratereductor to remove
nitrate. The Deniballs supply the surface area and the food for the bacteria at the same time. This
means that a Nitratereductor filled with Deniballs has not to be fed for a longer period - up to one
year. The Deniballs need - especially in a salt water tank - a longer period to reach their full
capacity. During this four to eight weeks, 1 tablet of Denimar per day has to be added.

Maintenance
1.
Control the flow rate: The flow rate through the filter has to be checked regularly. The
optimum is approx. 0.5 to 1 l/hr. This has to be readjusted from time to time.
