Sodium Thiosulfate: This is the active ingredient that removes chlorine found in a large number of chorine removal products. So, if all you need is cheap chlorine removal, this is the product to use. It can be overdosed without harm. In fact, it is a very effective Redox Reducer, eliminating oxidizing free radicals from the water. Overdosing is actually a good thing. Does not remove chloramines. If you have chloramines, it will break the chlorine/ammonia bond, leaving the ammonia to be handled by your bio filter.
Dose: Dissolve 1 lb of crystals into 1/2 gallon of distilled water and then use this solution at 1 drop per gallon of tap water to dechlorinate the tap water.
The Dechlorinator: Sodium Thiosulfate Crystals destined to impress, and priced at only $3.95.
