I have a 28 gal bowfront tank that has been up and running for about a year and am now thinking about converting to live plants. I want it to be a low-tech setup and am interested in java fern, anubias, crypts, etc. The tank is 18 inches high and 24 inches wide. I know that I need to upgrade my lighting but am totally confused as to what to get....T8 dual fixture, T5HO single fixture, or some kind of LED fixture. The more I read, the more confused I get...please help!
