Used for the neutralization of chlorine and/or Ovadine (PVP Iodine) solutions at hatcheries and aquaculture facilities.
Sodium Thiosulfate can be used for the neutralization of chlorine and/or Ovadine (PVP Iodine) solutions at hatcheries and aquaculture facilities.
Chlorine is highly toxic to fish and crustaceans so, whether disinfecting tanks or equipment with sodium hypochlorite (bleach) or using tap water during transport or stocking, it is crucial to remove chlorine prior to the introduction of fish or other aquatic life.
For the neutralization of Chlorine solutions: – The amount of sodium thiosulfate required can vary with the pH of the water. A range of approximately 2 to 7 parts sodium thiosulfate to neutralize one part chlorine is generally suggested, for example to neutralize 1 liter of a 200 ppm chlorine solution, approximately 0.4 – 1.4 grams of sodium thiosulfate would be required or to neutralize one gallon of a 200 ppm chlorine solution, approximately 1.5 – 5.3 grams would be required. The use of a chlorine test kit is recommended to determine final chlorine concentrations.
