I've never had a planted aquarium but I absolutely love the look of them. I have read lots of posts about how you need this and that and CO2 with this and a whole bunch of stuff I find confusing and expensive. I want a relatively small planted tank (5-10gal), and I know that plants that require high amounts of light will definitely need CO2, but I was just thinking about some low to medium light plants like, java moss, amazon sword, java fern and maybe some anubias nana. I know I will need to add some soil for them and about 1-2 watts a gallon but could I skip on the CO2? And what else would I have to do if I don't need to add he CO2? I don't really mind if they don't grow very fast. Thanks!
