The convenient method of CO2 fertilization

The system with the practical disposable CO2 cylinder. Ideal whenever replenishing CO2 cylinders is awkward or the nearest CO2 filling service is far away. No annoying waiting for the CO2 filling service.

Uninterrupted supply with reserve bottle: With a replacement bottle in the base cabinet of the aquarium there will be no interruption in CO2 fertilization, should your original bottle run out at the weekend, for example.
