When oxygen levels fall below 5 mg/l, fish are stressed. At oxygen levels of 1–2 mg/l, fish die. The amount of oxygen that can dissolve in water (i.e., the saturating concentration of oxygen) depends on water temperature. Colder water can hold more oxygen than warmer water. You'll see for yourself just how much more in this project.
effects of too much oxygen

What can happen if you oxygen LPM is turned up too high?
Excessive oxygen, wide swings of oxygen, and too little oxygen can all be potentially harmful. Exposure to high oxygen levels, rapid and wide changes in oxygenation, sustained hyperoxemia (increased oxygen content of blood), and episodes of hypoxemia (insufficient oxygen content of blood) are all thought to be deleterious to the developing ...

Oxygen is a life saving drug for hypoxaemic residents. Giving too much oxygen is unnecessary as oxygen cannot be stored in the body. COPD residents (and some other residents) may be harmed by too much oxygen as this can lead to increased carbon dioxide (C02) level. Other residents (e.g. cardiac / stroke) may also be harmed by too much oxygen.

May 03, 2013 · Nevertheless supersaturation can be harmful to fish and other aquatic organisms. Capillaries in the fishes gills can rupture or tear from too much oxygen. Fish with this condition usually die. It is referred to as gas bubble disease. Streams that have a dissolved oxygen saturation percent value of 80- 120% are considered to be excellent.
