Watch how to use CO2 System Bio

Watch how to add new Activator to recharge/refill your CO2 system Bio

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.

  • For improved growth of easy and medium plants
  • 60 days CO2 for a low cost
  • Safe to use
  • Easy to refill and recycle


How to use the product,

Part 1,

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

Part 2 - 24 hours later,

  • Add 1 portion of Activator in 200 ml of lukewarm water. Max. 35 °C.
  • Leave for 5 minutes and stir until Activator is dissolved in the water.
  • Add the solution to the bottle.
  • Insert the gasket into the air cap and place the cap on the bottle.
  • Attach the air hose to the bottle and connect the bottle to the CO2 Diffuser.
  • Place the CO2 Diffuser in the aquarium.
  • Wait for CO2 production to start. This usually takes a few hours, depending on the temperature.
