How should I make a good dechlorinating solution? I have read about some pretty high doses, like 250 grams in 500ml of water to make a stock solution.
A: First, let’s tell our reader how to get dechlorinating granules, Sodium Thiosulfate:
See below for link to find like, 5 pounds of sodium thiosulfate for overnight delivery.
If you put 130 grams in a liter jug, then add water quantity sufficient to make 1 liter, your stock solution will contain 130 grams/Liter.
Each teaspoonful [5 cc] will contain 650mg active Sodium Thiosulfate. This is a 13% solution.
Simply add 2 drops of the stock solution per 1 gallon of the body of water to be treated . One liter of your solution can treat 10,000 gallons. Over-dosage is virtually impossible.
Another method with the same results is to put 500 grams in a gallon jug, q.s. to 1 gallon then you have the same 650mg per tsp. [13% solution] Add 2 drops of the stock solution per gallon.
One gallon can treat 37,850 gallons or more.
