I don't think this symptom could be caused by running CO2 at night.
Gasping at the surface is caused by oxygen shortage. If the fish are
gasping at the surface in the morning then it probably means that the tank
is overpopulated and/or over fed and that you don't have enough
circulation to keep it oxygenated. The symptom would disappear after the
lights come on because the plants oxygenate the water.
