I have this 20L aquarium and I would like to grow Pogostemon Helferi in it. I wanted to know if CO2 is required for this plant or if it will be ok to use Excell liquid carbon. I will be using EI as a dosing regime. Tropica says that CO2 is not required to grow this plant and that it would just grow slower without CO2.

Any thoughts?
