ZC-II Co2 Generator

Product details

The ZissAqua ZC-II, also known as the CO2 generator, is an adjustable generator that can easily add CO2 to aquariums up to 200 liters.

• Suitable for aquariums up to 200L
• Dimensions: 12×11.5×27.5cm

The ZC-II is used outside the aquarium and introduces CO2 into the aquarium through a diffuser. CO2 promotes lush plant growth and lowers the pH of the water. This reduces the risk of infections and diseases in animals, making it helpful for creating the right conditions for aquatic life. ZC-II is suitable for both novice and professional aquarium enthusiasts. (Can it also be used in a terrarium?)

Unlike conventional bio CO2 generators, the ZissAqua ZC-II works directly. It does not produce unnecessary ethanol and operates without being affected by ambient temperature. The refill pack lasts for more than 45 days. The produced CO2 has a purity of 99% and operates at a constant rate.

The set includes:

1x ZC-II CO2 generator

1x ZD-200 CO2 diffuser

1x air hose

The refill pack is not included with the set and must be purchased separately. The ZCR-160 refill pack can be found here.

Instructions for Use:

1. First, close the speed control valve #3. (Important)

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

3. Add about 200 ml of water to #2 powder tank while simultaneously rinsing the red rubber main seal.

4. Place the #1 Up Solution Tank on the #2 Down Powder Tank and close it.

5. Open cap #4 and add the liquid from the ZCR-160 refill pack to the #1 Up Solution Tank. (Please check if the #3 speed control valve was closed before adding this.)

6. Close cap #4 and install the ZD-200 diffuser in the aquarium.

7. Open speed control valve #3 and adjust it to allow the solution from the #1 Up Tank to drip through drip hole #5. (Kit of 160 g: one drop every five to eight minutes)
8. Mark the position of the #3 speed control valve at the top with a marker. This makes it easy to reset it for the next installation.
9. Once again, check if the top solution is descending at the speed you set.

• If the solution is descending but the ZD-200 diffuser is not producing CO2, loosen the #1 Up solution tank and rinse the red main seal again with water as described in step 3, then reconnect.
• If you submerge the entire ZC-II underwater, you can easily check for leaks.

1. Use continuously for 24 hours: Closing speed control valve #3 can stop CO2 production, but not immediately. Use continuously for 24 hours unless you want to stop for a long time.

In the case of a 100-liter aquarium, one drop every 6 seconds from the bubble counter delivers a 20 ppm carbon dioxide concentration. With over 40 ppm carbon dioxide concentration, aquarium animals can die.

Refill not included.
