What is Dissolved Oxygen and Why It's A Critical Water Quality Parameter
Dissolved Oxygen Water Quality
Fish, insects and beneficial microorganisms depend on adequate dissolved oxygen to survive. Most aquatic species require DO levels above 5 mg/L to remain healthy, and when oxygen levels fall below this range, organisms experience stress, reduced growth and weakened immune systems. Prolonged low-oxygen conditions can lead to fish kills and long-term ecosystem damage.
