Nitrite is much less toxic when '''chloride''' is present, possibly because chloride inhibits nitrate absorption across the gills.

'''Sodium chloride''' is the most available and cheapest source of chloride.

Haemaglobin levels should return to normal within 12-24 hours. If severe anaemia is present '''recovery may take weeks'''.

The original cause of the nitrate toxicity should be resolved and levels of nitrate in the water can be reduced through '''water changes, biological filtration and decreased feeding'''.

Prevention involves ensuring an '''adequate levels of chloride''' in the water at all times. Most waters already have enough chloride and prophylactic treatment is unnecessary.
