Safety informations
• The reactor unit should not be run 24-7 on small tanks (due to the pH lowering effects of a calcium reactor).
To obtain the best results run the unit for 8 -10 hours per day. The reactor should start to run 4 hours after the
lights have come on. This will enable the highest pH to be maintained within the aquarium.
• If the reactor is running at maximum capacity then to reduce the likelihood of carry over of excess CO2 into
the tank run the outlet through a further cup of reactor media to degas the water before it returns to the tank.
• Use equipment only for its intended use.
• Do not install outdoors or near sources of extreme heat. Avoid exposure to UV.
• Install out of the reach of children - special attention should be given to ensure children cannot access the
CO2.
• Check the reactor every 3 months, or at least when refilling. It is recommended to check the reactor output
flow rate and pH on a weekly basis.
• Use media with a grain size of at least 8-10 mm, and preferably 12-15 mm or larger. This ensures optimum
flow behavior.
• Media contains CO2 insoluble compounds and over time these will collect as “sludge” on the bottom of the
reactor and should be removed at regular cleaning intervals.
• Regularly check the circulation pump and impeller. To do this, drain the reactor and disconnect all cables. The
pump motor can easily be removed from the impeller housing by twisting in an anti clockwise direction.
Fonctionnement incorrect du réacteur - problèmes possibles :
1. The reactor gets the air in and there is too much CO2 in the system.
Answer: make sure the pressure in cylinder is correct and the gas metering is not faster than 1-2 bubbles per
second. If your pressure gauge does not allow a precise adjustment, we suggest that you buy a sufficiently
accurate valve, as the reliable and correct operation of the whole system largely depends on this component.
Make sure the optical sensor is correctly plugged to the controller.
2. The optical sensor does not indicate a correct CO2 level – an error message appears on the controller
display.
Answer: make sure the pressure in cylinder is correct and the valve on the cylinder is not closed. Recheck the
gas flow between the cylinder and the solenoid valve. Make sure the solenoid valve is plugged to the controller.
Set the water flow at the pump according to the requirements of your aquarium. We suggest that you start from
500ml/h and increase slowly according to needs.
Remember that before starting the reactor the water parameters such as Ca and kH should be adequately pro-
portional relative to each other. The reactor is not for balancing the parameters, but for supplementing them in
proportional amounts.
3. Circulation pump not running(no water circulation in the reactor).
Answer: Air lock in reactor – turn off circulation pump than release gas build up by loosening gas collection trap
screw. Before turning pump on, completely refill reactor with water.
Check the CO2 supply rate.
Check impeller not jammed with media/sludge.
4. Circulation pump is too hot during operation:
Answer: See above.
5. Circulation pump rattles:
Answer: Remove the circulation pump motor. Clean any granular particles or debris.
6. Discharge from the reactor is too low.
Answer: Check flow in and flow out for blockages - replace the hoses if necessary. Check dosing pump tubing
against any damages.
7. No bubbles in the bubble counter:
Answer: Check the CO2 bottle is not empty. Check supply hoses for leaks
