Oxygen is extremely important to almost all organisms and very few can live without it. With the exception of anaerobic bacteria, all the organisms we keep in aquaria require oxygen to survive. It is required for respiration by all aerobic organisms and is generated by photosynthesis by photosynthetic organisms. The saturation level for oxygen in saltwater at tropical temperatures is approximately 6.5 mg/l .

How is oxygen used?
Oxygen is used for respiration of all living organisms.
How does oxygen get into the water?
Most of the oxygen in the water in an aquarium gets there by dissolving into the water from the interface between water and air. Some of it will also come from the phytosynthetic organisms (algae, zooxanthellae) within the system producing excess oxygen during daylight hours.
What factors affect the amount of oxygen in the water?
How do I increase the amount of oxygen in the water?
Increase circulation and water movement at the surface, and improve movement of air over the aquarium.
