Maintaining Oxygen Levels in Fish and KOI Ponds
Severe environmental stressors are the most frequent causes of sudden fish death in garden ponds or other fish habitats, and the lack of oxygen in the water is the number 1 stressor of all.
Two major factors contributing to fish-pond oxygen loss concern blooming algae. During daylight hours, algae make oxygen; during the night,however, the plants take oxygen. If algae are profusely blooming, the plants deplete all the pond's oxygen during the night, which in turn, causes fish inhabiting the pond to die.
Another way that algae trigger oxygen loss is by dying suddenly. Algae-bloom death occurs naturally or from chemical treatment of an algaecide. When algae die suddenly – from either caus...
