Sodium thiosulfate is a compound used to neutralize chlorine. Municipal water sources must be treated. Use sodium thiosulfate for instant neutralization of chlorine, chlorimines (do not add directly to water containing fish). Use as directed, (excess levels of sodium thiosulfate up to 100 ppm will not harm fish). Made in USA.
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. To neutralize 1 liter of a 200 ppm chlorine solution, approximately 0.4 - 1.4 grams of sodium thiosulfate would be required. 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.
