6. Carefully open the fine needle valve on the CO
same time. (Picture 2, bubble counter) Start with approx. 10 – 15 bubbles / minute.
7. Remove the vent plug from the first (top) capacity hole (Picture 3).
8. Then adjust the quantity of CO
above the hole. The gas now collects inside the reactor and is diffused into the water flowing through. The water enriched with
CO flows back into the aquarium through the bottom strainer cap.

11. If the CO permanent test is still blue one day later, the capacity of the reactor needs to be increased. To do this, close the 1st

capacity hole with the vent plug and open the 2nd one.
12. Adjust the addition of CO
hole and open the 3rd one. You can continue doing this until you reach the 6th capacity hole (Picture 3). As soon as you have
found the right diffusion capacity, the CO

Cleaning: Please ensure the cascade inside the reactor is kept clean. Cleaning is easy. Remove the bottom strainer cap and pull
the cascade out from the bottom. Clean the inside of the reactor with the enclosed brush. A separate fine brush is enclosed to
clean the bubble counter.
