The water temperature should be reduced to increase the level of dissolved oxygen, and '''vigorous aeration and supersaturation''' with oxygen should be performed where possible. | For emergency treatment of chlorine or chloramine toxicity, fish should be immediately transferred to '''chlorine-free water'''.
