Connections
The following connections are located at the Sulphur-Nitratereductor:
-
Inlet:
Here, you can connect a 6 mm air tube. At the inflow, you find an adjustion valve to
adjust the flow rate. The best value is approx. 0.5 - 1 l/hr (approx. 1 drop per second). The
adjustion at the inflow causes a delay until you can read the adjusted drop number at the drop
counter at the water outlet. The drop counter is mounted inside the aquarium, close to the
water level. If the flow rate is regulated in the outlet, the valve may not be closed completely
in order to allow produced nitrogen to escape. During the start phase in the first weeks, the
outlet valve should stay completely open.
-
Redox electrode:
Through this opening, you can put the special pressure resistant ORP
electrode with a special length and standard thread (PG 13,5) Aqua Medic order-No: 220.19.
-
Outflow to aquarium:
Here, you can connect a tube 8/6 mm.

Set-Up
The Sulphur-Nitratereductor is a hermetically closed system. The produced gas (nitrogen and CO
2
)
can escape through the water outlet. For this reason, the outlet should never be completely closed
because an eventual overpressure may escape through the water inlet and interupt the inflow.
The Sulphur-Nitratereductor
has to be placed in a way that the water can flow off either directly
back into the aquarium or into the filtration chamber. In a seawater aquarium it is advantageous, if
the outflowing water is flowing into the inlet of the protein skimmer or the trickling filter. In the
protein skimmer, the water is saturated with oxygen before it comes back into the aquarium.
Inflow: The inflow into the reductor can be realised as a bypass from the main circulation pump by
the included T pieces. In case of a Percula aquarium, the reactor has to be placed in the chamber
behind the trickle filter. There is a special adapter available (order-Nol 503.00-17 - not enclosed)
for connecting one of the pumps to the water current. Put the adapter on the pressure side of the
pump and stick it through the hole of the filter chamber.The flow rate is adjusted with the valve
and drop counter.

Starting
Before starting the Sulphur-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.
