Sodium Thiosulphate - 4 lb jar Venturi two 7" durable puck styleSodium thiosulphate is the main compound in most chlorine neutralizers. Anytime municipal water must be used for aquaculture, use sodium thiosulphate (or our other dechlorinating formula) for instant neutralization of chlorine but not chloramines. Dosage rates vary with the pH of the water, but rates between 1. 6 to 2. 6 parts sodium thiosulphate per one part chlorine should be adequate (excess levels of sodium thiosulphate up to 100 ppm will not harm
