Im new to the co2 thing but have read alot on it. I have a 20 gallon tank and was wondering what would be a good system for me. Im looking for something that comes with what i will need and is to where all i have to do is turn it on. Im not a diy type of person so any suggestions will be appreciated.

Or the question mabye do i even need a co2 setup. I will be growing low light plants and mid medium light plants. I havent figured out what light fixture i am getting but i aiming for a total of 2 watts per gallon. Most of my plants i plan on growing on rocks or driftwood.

What do yall think about it.

Which 20 gallon tank is it? 12" tall or 18"?? It only makes a difference because 40 watts of light at 18" is waaaaaya less intense than 40 watts at 12" (minus the gravel depth!).

Either way, you could probably do without co2. It will just mean slower growth and higher possibility of algae. Make sure you really stock up on plants to start, try to get as many as possible.
