Hi, Terror,
(That's what my mother used to call me when I was little. It doesn't sound right here, but . . . <g>)
I don't think that anybody has made this observation and if they have, I apologize, but with three anubias and a bare bottomed tank you certainly don't need CO2 of any kind.
If you want grow plants that need a substrate and you don't want to put one in your tank, you might try putting some gravel into a plastic tray. 1 - 2 inches deep, instead. Maybe put about a half inch of soaked MiracleGrow potting soil in there too, in a layer at the bottom. Use inert gravel that is 2 - 3 mms in diameter.
For plants try Hygrophila polysperma or java fern or any one of a number of lower energy plants.
Good luck!
Bill
