Well, if you have 2-3W per gallon, I suggest you try adding CO2.... even a simple DIY system with Yeast and sugar. U'll see marked results and u'll understand what the fuss is all about adding CO2.
Watch over fertilising the tank.... U'll be battling algae all the way. Made that mistake with my first tank.... Now I test for nitrates and Iron weekly.
Other than that.... a planted tank is a sight to behold.
