Tropica CO2 System Bio - Refill

CO2 is the most important nutrient for plants. Without a supply of CO2, plants will not thrive. CO2 System Bio is a simple solution that adds extra CO2 to aquarium plants. We recommend 20-25°C for optimal product performance. Ideal for low and medium maintenance plants and for aquariums up to 45L.

The contents of this package provide an additional 60 days of CO2 for your aquarium.
