Best carpet plant for low-tech?
Hey there! I am looking for suggestions on a good plant to use as a carpet in a low-tech situation (no CO2/Excel) - if possible, one that will grow okay in gravel (with no planting substrate). If I can't do a carpet with no planting substrate, I will have to think about mixing some in with the gravel. My tank has planting substrate at the back and gravel at the front, but I have decided I want to get my tank more heavily planted - the pics on this site are making me too jealous!
