Aquarium CO2

Adding CO2 to your aquarium is one of the best ways to grow lush, vibrant plants and achieve a professional-looking aquascape. CO2 systems help plants photosynthesise more effectively, leading to stronger growth, better colour, and improved resistance to algae.

Why Use CO2?

In a closed tank, CO2 levels are often too low to support dense plant growth. Injecting CO2 provides plants with the carbon they need to thrive and outcompete algae.
