What size tank and how much light do
you have?. Adding CO2 to a tank without sufficient light for the plants to
use it really will do nothing.

It's only a 60 litres (16 gallons) aquarium. But i'm already looking into it
since
i'm planning to get a tank of at least 80 gallons (300 litres).
I'm not sure what "strength" the light is giving in the tank. I think it's
25 watts.
