5.5 Plug the DC jack into the back of the unit and the AC adapter to a wall
mounted receptacle. The digital display will show the current ORP of the
Aquarium water.
5.6 Position the selector switch on the front panel to ”Ozone” and set the
desired level of ozone output. The digital display shows the ozone level in
milligrams of ozone per hour (mg/hr). As a rule of thumb set 10 mg/hr for
every 25 gallons (100 liters) of aquarium water.
NOTE
: The ozone level can
only be set if the ozonizer is currently producing ozone i.e. the red indicator
light is illuminated. This will only occur when the “ORP Set point” is higher
than the “ORP reading”.
5.7 Position the selector switch on the front panel to “ORP set point” and set
the desired redox potential. (Recommended b300 and +350 mV.)
5.8 Switch on the air pump, check that ozone is being produced and that the
ozonizer is being switched on and off correctly as the ORP reading varies.
Notes:
a. Redox values differ considerably in different parts of the aquarium. To obtain
consistent results one should determine a fixed position for the electrode.
Other factors influencing the redox potential are: pH , lighting, temperature,
feeding and even the time of day. In order to compare your results and
evaluate the changes, take and note several readings at the same time every
day. In this way you will be able to compare the different measurements.
b. It may take several days to reach the set point. Preferably the ozone generator
should not be set higher than 15 mg/hr/25 gallon (100 liters). Monitor the
redox potential carefully for a few days (compare readings taken at the
same time every day). If after several days the ORP does not go up significantly,
slightly increase the ozone production rate but not more than to 25mg/hr/25
gallon (100 liters). Once the set point has been reached reset the ozone
production to between 5 and 15 mg/hr/100 liters.
c. Care should be taken not to move the set point and ozone adjustment
knobs (after setting) as this will alter the settings.
d. Humidity may decrease ozone production by 50%. All ozone production
settings mentioned in this manual assume that dry air is introduced to the
ozonizer.
6. Electrode
The AquaZone PLUS unit is calibrated and tested with the Reagecon Platinum-
Ag/AgCI electrode which is recommended for use with the AquaZone PLUS;
should another type/brand of electrode be used with the AquaZone Plus, ensure
that you:
Take a reading with your electrode in “Redoxsol” Red Sea Fish Pharm’s Electrode
test solution. If you receive a reading different to that printed on the test
solution bottle, follow the supplied instructions carefully on how to use this
electrode with the AquaZone Plus unit.
The electrode should be cleaned every 3 or 4 weeks.
(Recommended:
ElectroClean, Red Sea Fish Pharm’s Electrode Cleaner). After cleaning allow 6
hours to stabilize during which ozone should not be administered. The expected
life span of an electrode is approximately 1 to 2 years; after this period to avoid
false readings and incorrect ozonization it should be replaced.

4. AquaZone 50/100/200 – Installation and Operation
4.1 Connect your air pump to the (IN) air tube connection on the back panel.
Connect the (OUT) air tube connection to the Ozone Reactor or protein
Skimmer. (it is advisable to install an ozone safe non-return valve).
4.2 Switch on your air pump and check that air is flowing freely through the
unit.
4.3 Set the ozone output to the desired level as recommended in section 1.3
Above. The scale is set as a percentage of the maximum output of 50,
100 or 200 mg/hr according to the model purchased.

4.4 Plug the DC jack into the back of the unit and the AC adapter to a wall
mounted receptacle.
4.5 The red light on the front panel indicates that the unit is generating ozone,
however it will only be effective when air is forced through the unit.
4.6 It is recommended to use the AquaZone together with a redox controller.
5. AquaZone Plus 50/100/200 – Installation and Operation
The AquaZone PLUS unit includes a ozonizer combined with a redox controller
that constantly measures the redox potential (ORP) of your aquarium. When
the measured ORP in the aquarium falls below the desired level (ORP SET
POINT) the ozonizer is automatically switched on and will remain on until the
desired ORP is reached. The AquaZone PLUS provides easy adjustment with
digital display of both the desired ORP and the output level of the ozone
produced.
The AquaZone PLUS cannot be used without an ORP electrode (see section 6
of manual). The Reagecon ORP electrode is supplied as part of the AquaZone
Deluxe Kit or can be purchased separately. Before using the Reagecon ORP
electrode remove the plastic cap and rinse the tip in running water.
5.1 Immerse your ORP electrode about halfway into the aquarium water. It
should be installled in a flowing water, preferably in a dark place, to avoid
fouling with algae. A good place is in the flowing water near the overflow
siphon or overflow compartment of your aquarium. An alternative is the
sump of your biological filter. Connect the electrode cable to the BNC
socket on the front of the unit. If the AquaZone PLUS unit is located under
the water level install the electrode with a drip loop in the cable.
5.2 Connect your air pump to the (IN) air tube connection on the back panel
of the unit. Connect the (OUT) air tube connection to the ozone reactor
or protein skimmer. (it is advisable to install an ozone safe non-return
valve).
5.3 Switch on your air pump and check that air is flowing freely through the
unit and that there are no leaks at the connections. Switch off pump until
setup is complete.
5.4 Turn the “Ozone” knob to the minimum position and the “OPR SET POINT”
knob to maximum. Position the selector switch to “ORP READING”.
