According to research done by Tropica, the impact on growing speed from CO2
is much bigger in a low light tank than in a high light tank.
In a tank with much light you MUST have CO2 in order to get the plants to
grow, in a low light tank you do not need it, but it really help the speed
and the way the plants look.
I had a low light tank less than 1 watt/gal (look at my webpage 66gal tank)
some people from USA even told i was lying when i said i did grow plants in
that amount of light. Everything was growing fine, but i wanted more so i
started to inject CO2, and everything really took of, my anubias normaly got
1 new leave every week, with CO2 it have 4-5 every week. And everything else
grow very fast.
So CO2 is also very important in an low light tank.
