Collection: CO₂ Pressurised Bottles | Aquarium CO2 Systems for Plants

Unlock exceptional plant growth with pressurised CO₂ bottles, the most efficient method for delivering carbon dioxide to your planted aquarium. Aquarium plants are 90% carbon, making CO₂ supplementation essential for healthy, vibrant growth — without it, plants struggle to thrive long-term. Pressurised CO₂ systems provide consistent, reliable carbon delivery that far surpasses liquid carbon alternatives, supporting everything from carpeting plants to demanding red species. Whether you're running a high-tech aquascape or upgrading from liquid carbon, pressurised CO₂ bottles offer precise control, cost-effective operation, and dramatic improvements in plant health, colour, and growth rates. Available in various sizes to suit nano tanks through to large aquascapes, these refillable bottles integrate seamlessly with regulators, diffusers, and drop checkers for complete CO₂ management. Essential for serious aquascapers seeking professional results and lush, fast-growing planted tanks.
