Just want to make sure we are considering all essentials, as the balance in a planted aquarium is multi-faceted.
First, what exactly is your light? It's a 10g, so I assume incandescent (screw-in bulbs) and not fluorescent tubes? How many bulbs, and what type (make, watts, kelvin rating, everything you can tell us will help).
Second, root fert is good for swords but not essential if a good liquid is being added sufficiently; I've had thriving tanks of several species of Echinodorus (swords) for 20 years and only once for one year did I use root fertilizers and while it did make a difference, they grew and are again growing well without. The Tetra fert is presumably FloraPride; their website says it contains "a combination of nutrients including potassium and iron" but they don't say what else is in it in the way of nutrients, which leaves me skeptical. When I know more about your light, I may have further advice on using this fert with or without root fertilizer.
