Circulation of water within a planted tank is very important both for even distribution of nutrients and also dispersal of co2. When is surface agitation of water i.e. when the water surface is broken co2 is released based on conc difference between that in the water and the air. O2 is taken into the water due to the same reason.
Now.. if u don't have injected co2 that's OK. In low light set ups with slow growing plants that's not necessary. Just continue having good circulation around the tank and if u have fauna a mild ripple at the surface will make sure they get their o2. Just position ur wavemaker so that it doesn't cause too much surface agitation. Hope that's clear.
