You can do DIY CO2 if you want, but I am not sure of exactly what lighting level 13W CFL is on a 5.5g. I would warn you that the Cabomba will likely be very hard to take care of, but hopefully you will have success with it. I would say to not worry about the CO2, until you find a definite answer.
Excited to see some pictures.
