Re: DIY Chlorine Remover (was Insto-Chlor)
In the January 1992 issue of AFM (no.4 vol.4) Todd C. Wenzel wrote an
article that shows how you can make a chlorine Remover using Sodium
Thiosulfate. Here are his instructions for making a formula for a small
batch and a big batch:
Assuming a worse case of 2.0 ppm chlorine in your water:
Place 5 teaspoons of sodium thiosulfate into a container and fill water up
to the 44 milliliter (ml) mark. This creates a 2 drops per gallon solution
that will treat 450 gallons (1700 litres) of water.
Place 1125 grams (2.5 pounds) sodium thiosulfate into a container and fill
to the 2 litre (l) mark. This creates a 2 drops per gallon solution that
will treat 20000 gallons (75000 litres) of water.
The author say that sodium thiosulfate is essentially non-toxic to aquatic
animals and small amounts of excess can be tolerated. Gross excesses can
be responsible for dropping pH in a tank. I hope this helps. Good Luck.
