CO2 Natural Plant System Replacement Parts

Keep your Hagen CO2 Natural Plant System running at peak performance.

Activator and Stabilizer Packets
Replacement Activator and Stabilizer Packets ensure steady CO2 production for healthy aquarium plants. Easy-to-use replacement packets produce CO2 through natural fermentation process and supplies CO2 for up to 28 days.

• Remove CO2-resistant tubing and cap of your CO2 Natural Plant System.
• Dispose of contents as desired (contents are 100% biodegradable).
• Thoroughly rinse out fermentation canister and cap. Do not use soap or detergent.
• Add white table sugar (no other substitute) to the first level indicator inside the canister. Add full contents of one Stabilizer Packet.
• Add full contents of one Activator Packet.
• Add lukewarm water (68°-86°F/20°-30°C) to the second level. Do not use aquarium water. Stir contents gently for faster activation.
• Replace cap. To close, turn counterclockwise once to align the threads, and then proceed to close by turning clockwise. IMPORTANT: To prevent CO2loss, turn cap clockwise until initial resistance is met and then tighten securely with an additional quarter turn.

NOTE: Once the fermentation is complete, the air tube may become filled with water through thermal conditions. While servicing the unit, make sure that the air tube is fully emptied of water by raising it above the aquarium water level or by blowing into it. This will ensure that no aquarium water inadvertently leaks outside of the aquarium while servicing is taking place.

How to Maximize the Benefits of CO2 Injection

• The CO2 Natural Plant System relies on the natural process of fermentation to produce carbon dioxide. Maintain an ambient temperature range of 70?-80?F (21?-27?C) - for optimum results 68-72 ?F (20-22 ?C).
• Install power filter outputs so that the aquarium water surface is not excessively agitated. The greater the water surface turbulence, the faster the rate of carbon dioxide will leave the aquarium. Ensure that there is just enough water surface movement to satisfy the oxygen requirements of fish, demonstrated by natural behavior and breathing.
• Test pH and KH regularly. It is recommended to perform a pH test prior turning lights on and off. The pH value range will often increase as buffering capacity (KH) decreases and/or plant population increases. Always use a pH Stabilizer to replenish buffering capacity (KH). It is a good source of bicarbonates (source of carbon energy) for some plants and nitrifying bacteria.
• Maintain aquarium light intensity by cleaning deposits regularly. It is recommended to clean fluorescent tubes on a weekly basis and replace them at least annually.

The Effects of CO2 Injection
Carbon dioxide is the most easily assimilated carbon source for plants. Approximately 40% to 50% of dry weight composition of a plant is carbon. Through the invigorated growth of aquatic plants, the aquarium owner can expect a higher degree of water quality.

CO2 injection benefits fish due to improved water quality, and also provides a safe and gradual method of reducing pH values. Many aquatic plants thrive in mildly acidic pH ranges, and suitable species of fish for planted aquariums often prefer these water conditions.

The plants do respond well to the CO2. In fact, the stem plants grow almost too fast and need constant trimming. The system is easy to set up. Back-siphoning can be a problem. A check valve would be a nice enhancement. I do get concerned by a white substance that forms at the end of the bubble hose.

Great product! I have two in a 55 gallon tank. The plants are so thick that I have to trim them back every two to three weeks. I am able to grow plants that wouldn't grow before I had CO2 in the tank.
