I have seachem root tabs. I also have a tank with BDBS as a substrate and am wondering what would be a good low tech carpenting plant that would work with those two elements? I get a pretty decent carpet with monte carlo and amazonia soil with no CO2. Can I expect similar results with root tabs with the sand? What about microswords? Any foreground plants, but does not necessarilly have to be carpeting? I already have a carpet of s. repens, so that's out of the equation.
