I think it would be Oxygen during the day (byproduct of photosynthesis) and Carbon Dioxide at night (byproduct of respiration). Incidentally the shift between these two processes when your lights go on/off is what causes the day/night pH cycle as a result of changing the equilibrium point for CO2 and carbonates in your tank water.
