Why Your Aquatic Plants Need CO2
Carbon dioxide is an essential nutrient for photosynthesis in aquatic plants. A consistent, controllable CO2 supply encourages faster, healthier growth, richer coloration, and a more natural planted-tank ecosystem.

Frequently Asked Questions
Q: What size aquarium is this CO2 generator system compatible with?
A: This aquarium CO2 generator kit is designed for planted fish tanks up to 90 cm in length. For larger tanks you may need multiple diffusers or a higher-capacity CO2 system.
Q: Does the solenoid valve work with both US and international power outlets?
A: Yes. The micro solenoid valve is compatible with 110–220V power supplies, making it suitable for use in the United States, Europe, and most other countries worldwide.
Q: How do I know the CO2 cylinder is safe to use?
A: The stainless steel cylinder features a convex bottom design engineered to withstand pressures up to 150 kg without rupturing. An automatic pressure relief valve activates at approximately 75 kg to safely vent excess pressure, giving you added peace of mind.
Q: What does the three-stage filtration system do?
A: The built-in three-stage filter removes impurities from the CO2 before it enters your aquarium, ensuring that only clean, pure carbon dioxide reaches your aquatic plants and fish — protecting both your livestock and the tank ecosystem.
Q: Do I need any special tools to set up this CO2 kit?
A: No special tools are required. The quick-plug connector allows for fast, easy assembly and material changes without additional hardware. Detailed installation instructions are included with the kit.
