SAFETY INFORMATION
• 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 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.
• Use only the original tubing of the reactor (genio-system silicon tube). Normal PVC hoses become brittle when
exposed to acidic water and CO2.
• 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.
TROUBLE SHOOTING
Circulation pump not running
(no water circulation in the reactor):
• 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.
Circulation pump is too hot during operation:
• See above.
Circulation pump rattles:
• Remove the circulation pump motor.
• Clean any granular particles or debris.
Discharge from the reactor is too low:
• Check flow in and flow out for blockages - replace the hoses if necessary.
No bubbles in the bubble counter:
• Check the CO2 bottle is not empty.
• Check supply hoses for leaks.
