I have been using Narrow Leaf Java Fern attached to wood with success in high light tanks. I am using CO2 but I have found that doing weekly water changes (I use straight from the tap) and weekly dosing with the Seachem products (I just follow the written directions on the bottles) works for me and keeps them going quite well. If you are running a small tank (under 50 gallons) and want to try CO2 just set up a do-it-yourself setup with yeast. It is cheap and simple, I have run it on my 20 and 40 gallon tanks with no problems. I usually run two 2-liter bottles in tandem and can get a 3-4 week charge out of them before redoing the mixture.
