Stainless Steel Aquarium CO2 Generator System Kit – 1L & 2L
Stainless Steel Aquarium CO2 Generator System Kit
Supercharge your planted aquarium with this professional-grade Stainless Steel CO2 Generator System Kit. Engineered for hobbyists who demand reliability and efficiency, this carbon dioxide reactor kit delivers a steady, controlled supply of CO2 to fuel lush aquatic plant growth — all while keeping your fish safe and your tank thriving.
Why Choose This CO2 Generator Kit?
- Premium SUS304 Stainless Steel Bottle — Thick, corrosion-resistant construction is far more durable and reliable than standard plastic bottle generators, ensuring long-lasting performance.
- Built-In Safety Valve — Automatically opens when pressure exceeds safe maintenance levels, giving you peace of mind and protecting your aquarium equipment.
- Polymer Microporous Filter Element — Effectively blocks and absorbs impurities from the generated gas before it enters your tank, delivering clean, pure CO2.
- Aluminum Alloy Valve — Lightweight yet sturdy, the aluminum alloy valve pairs perfectly with the stainless steel body for a professional-grade setup.
- Available in 1L & 2L Capacities — Choose the size that suits your aquarium; each reaction cycle lasts approximately 3–4 weeks.
- Easy Raw Material Replacement — Simple, step-by-step process to swap out spent materials and get your system running again quickly.

Important Usage Notes
- During the chemical reaction, the bottle temperature may drop and produce water mist inside — this is completely normal.
- Always keep the cylinder upright; do not place it upside down or tilted.
- Use only citric acid and baking soda as raw materials (purchased separately). Do not overfill or reuse spent materials without replacing them.
- Start at a low flow rate of 1–2 bubbles per second and adjust gradually. Excess CO2 can be harmful to fish — monitor your tank closely during initial setup.
- Raw material replacement: Confirm pressure reads 0 → remove bubble counter and airline → release remaining gas → turn off solenoid valve → loosen valve counterclockwise → pour out waste liquid → rinse bottle interior with clean water → add fresh raw materials.

Frequently Asked Questions
Q: What raw materials do I need to use with this aquarium CO2 generator kit?
A: You will need citric acid and baking soda, both of which are purchased separately. For the 1L model, use 100g citric acid + 100g baking soda + 200g water. For the 2L model, use 200g citric acid + 200g baking soda + 300g water. These common household ingredients react to produce a steady flow of CO2 for your planted aquarium.
Q: How long does one charge of raw materials last in this CO2 generator system?
A: Each charge of raw materials typically lasts approximately 3 to 4 weeks, depending on your flow rate setting and ambient temperature. Starting at 1–2 bubbles per second is recommended and helps extend the duration of each reaction cycle.
Q: Is this CO2 generator safe for fish?
A: Yes, when used correctly. The built-in safety valve automatically releases pressure if it exceeds safe levels, and the microporous filter element removes impurities before CO2 enters your tank. Always begin with a low bubble rate (1–2 bubbles/sec) and monitor your fish during initial setup, as excessive CO2 can be harmful. Gradual adjustment ensures a safe environment for both plants and fish.
Q: What is the difference between the 1L and 2L versions?
A: The 1L model (190 × 102 mm) is ideal for smaller or nano planted tanks, while the 2L model (340 × 102 mm) suits medium-to-large aquariums requiring a greater CO2 output. Both versions use the same stainless steel + aluminum alloy construction and offer the same 3–4 week reaction cycle per charge.
Q: Why is stainless steel better than a plastic CO2 bottle generator?
A: The SUS304 stainless steel bottle is significantly more durable, corrosion-resistant, and pressure-stable than standard plastic alternatives. This ensures a longer service life, a safer operating environment, and more consistent CO2 output for your aquarium plants over time.
