CO2 is the most important nutrient for plants. Without a CO2 supply, the plants will not thrive. CO2 System Bio is a simple solution that adds extra CO2 to the plants in the aquarium. We recommend 20-25 °C for the best use of the product.

  • 60 days CO2 for a low cost
  • Safe to use
  • Easy to refill and recycle

How to use the product

    1.  Pour 300 ml of hot water in the bottle. Approx. 50 °C.
    2. Put on the cap (without air nozzle) and shake the bottle vigorously for one minute, or until the contents are thoroughly mixed.
    3. Then leave the bottle at room temperature for a minimum of 24 hours until the content has turned into a solid mass.
    4. At the same time, soak the CO2 Diffuser in clean water

      24 hours later

    5. Add 1 portion of Activator in 200 ml of lukewarm water. Max. 35 °C.
    6. Leave for 5 minutes and stir until Activator is dissolved in the water.
