UK – CO₂ Basic Set
For aquariums ≤ 50 litres
There are three important factors for good aquarium plant growth: light, carbon dioxide (CO₂), and nutrients. Normally, aquarium water does not contain enough CO₂ for healthy plant growth. With this handy CO₂ Basic Set, you can easily increase the CO₂ concentration in the aquarium water for better plant development.
The CO₂ Basic Set provides the following benefits:
Improved growth of aquarium plants
Healthier, flourishing plants that help prevent algae growth
Prevention of biological deacidification and deposits on stems, leaves, and glass
