In general, getting plants to carpet nicely (and not just grow upwards) requires higher light. Higher light means that you will driving the plants harder, necessitating fertilizers (these include water column) and CO2.

I would go with water column fertilization in addition to root fertilization (actually, I rarely use root fertilization since I find it messy; I rescape frequently, and disturbing the root fertilizers is usually not good).
