Thanks a lot for the replies everyone. I guess what you guys are trying to tell me is that, I have to learn to walk before I can run.

I have already DIY-ed the 4X36W PL-L lights and it seems like overkill to me. I normally only have 2 lights on, as so far I have only got some Java Fern, Java Moss and Nana in the tank.

My DIY Co2 should be up and working within the next few days. Will 1 bottle be sufficient?

Can you please reccomend some other plants for a beginner like me?

Cheers
