Hi all, I was thinking of adding lileopsis (sp.?) and rotala macrandra to my desktop 5.5 gal tank. What would be a good soil to use with vermiculate? Potting soil or soil from my backyard garden which has a lot of clay in it? Also, would 30 watts of daylight flourescent be enough for r. macrandra in a 5.5 gal? If so, should I pot it? Many thanks, Stephen Morrison in Batavia Illinois
