De-chlorinators

Make your own De-chlorinators

Here is a tip to save you a little money. Follow these simple instructions to make your own de-chlorinator.

Make Your Own!

De-chlorinators are made from readily available, and incredibly cheap, chemical called "sodium thiosulfate". There are lots of formulas out there in regards to how much it takes to neutralize a given amount of chlorine. Here is just one of those formulas:

First, there are a couple of variables that you need to know, such as:

• Gallons of water to be de-chlorinated, or (G)

• Concentration of chlorine in mg/liter, or (ppm)

With these two pieces of information, you can plug them into this formula to see how much sodium thiosulfate you need:

G x 0.0038 (milliliters/gallon) x ppm x 3.49 (units of sodium thiosulfate/unit of chlorine) = grams of sodium thiosulfate needed

The Easy Route

You can also go the easy route and "ball park" your estimate. Sodium thiosulfate is very cheap and nearly impossible to over dose, so you can use this guideline:

• Two teaspoons of the crystals will de-chlorinate 500 gallons of fresh tap water

• Two tablespoons will de-chlorinate 1,500 gallons of fresh tap water.

• 1/3 cup will de-chlorinate 6,000 gallons of fresh tap water

• 1 cup will de-chlorinate 18,000 gallons of fresh tap water

Be aware that some municipal water supplies contain chloramine instead of chlorine. Using the de-chlorinator on water containing chloramine will leave you with ammonia, which will need to be eliminated with biofilters or ammonia binders.
