Looking for a high-performance, easy-to-use CO₂ system for your planted aquarium? The ZissAqua ZC-II CO₂ Generator is the perfect solution for both hobbyists and professional aquascapers. This adjustable, non-electric CO₂ generator delivers a constant and highly pure CO₂ output (99%), supporting vigorous plant growth and a healthy aquatic environment.

Unlike traditional bio-CO₂ systems, the ZC-II starts working instantly, without temperature sensitivity or unnecessary ethanol production. The unit is installed outside the aquarium and diffuses CO₂ via the included ZD-200 diffuser, effectively lowering the pH and reducing harmful pathogens and algae.

Setup Instructions:

1. Close valve #3 before starting (important).

2. Add the powder from the ZCR-160 refill kit to tank #2.

3. Pour ±200 ml of water into tank #2 while rinsing the red rubber seal.

4. Close the system by attaching tank #1 to tank #2.

5. Open cap #4 and add the liquid solution to tank #1 (ensure valve #3 is still closed).

6. Seal cap #4 and place the ZD-200 diffuser inside the aquarium.

7. Open valve #3 to control drip speed (±1 drop every 5–8 minutes).

8. Mark valve position to simplify the next refill.

9. Monitor the drop speed and adjust if necessary.

💡 Tip: If no CO₂ is released despite proper flow, rinse and reseal the red gasket as in step 3.
💧 To check for leaks, submerge the ZC-II in water.

Important CO₂ dosing advice:

• Use continuously for stable CO₂ output.

• One drop every 6 seconds = ~20 ppm in a 100L tank.

• Over 40 ppm may be harmful to fish and shrimp.

• Not recommended for terrarium use.
