Since the density of oxygen in an aqueous solution is about 0.7 kg/m3, then the
units of DO (mLDO/Lwater) may be divided by 0.7 to estimate oxygen concentration
Cs *, expressed as mgDO/Lwater. Aquaculturalists may estimate % saturation by
dividing concentration readings by Cs *. The central theme is that aeration is not
required if DO is above 100% sat.
