Expert Answer:

(The term percent saturation is often used for water quality comparisons. Percent saturation is the dissolved oxygen reading in mg/L divided by the 100% dissolved oxygen value for water (at the same temperature and air pressure).
 
The average saturation in an aquarium is about 70%. The level of dissolved oxygen varies throughout the day. A dissolved oxygen content of 5-7 ppm is sufficient, first signs of stress will show if the content drops below 4 ppm.
