An Economical Choice: Up to 5 Times Cheaper
A reformed CO2 fire extinguisher (with W21.8 threading) costs much less than a new CO2 bottle. On average, you can save up to 80% on the initial cost. A 2 kg bottle can last between 6 months and 1 year, depending on your CO2 flow rate — ideal autonomy to avoid frequent refills.
Tip: The savings can be invested in better lighting, quality plants, or an efficient filtration system.
Extended Autonomy and Optimal Capacity
With standard dimensions (56 cm tall by 11 cm diameter), a CO2 fire extinguisher offers a large gas capacity under pressure. This ensures steady diffusion for several months without frequent interruptions for refilling.
Ideal for aquarists with multiple tanks or demanding planted setups.
An Ecological Gesture for Your Aquarium
Choosing a reformed CO2 fire extinguisher helps reduce metal waste. You contribute to a sustainable approach while reducing the carbon footprint linked to manufacturing new equipment. A responsible solution for nature lovers!
Ease of Installation and Compatibility
These extinguishers can be easily connected to a standard regulator with W21.8 threading. No special equipment required: just a diffuser, tubing, and a bubble counter. Adoption is quick, even for beginners.
Result: better photosynthesis, denser plants, and a visually more attractive aquarium.
Safety: Precautions to Follow
- Overdosing: Excess CO2 can harm fish. Regularly test pH and KH to adjust flow.
- Leaks: Check fittings with soapy water to detect bubbles and prevent waste.
- Ventilation: Never use CO2 in poorly ventilated rooms. Ensure proper air circulation.
- Equipment: Use a solenoid valve and programmable outlet to automate diffusion only during daytime.
In conclusion: choosing a recycled CO2 fire extinguisher is a sustainable, economical, and effective choice to boost your plants’ growth while preserving the environment.
