The disinfecting effect is based on a series of reactions of chlorine or chlorine dioxide readily soluble in it. Two different chlorine compounds are formed: hydrochloric acid (HCl) with a low oxidation state of chlorine and hypochlorous acid (HCl) with a high oxidation state of chlorine.

Causes

When the fish are over-fed at the bottom of the aquarium, the anaerobic environment is formed from the remains of food, detritus, and feces, in which nitrates are converted to nitrogen.
