Granular Calcium Hypochlorite

All the water that will ever be is, right now. - National Geographic

Read the label of the pool shock closely! All you want to use for this is high concentration of Granular Calcium Hypochlorite and nothing else. Be careful to avoid the multi-function pool shocks that have chemicals like algicides and other 'multi function 4-in-1' products. All you want is Calcium Hypochlorite at 65% or stronger. Don't worry about the ingredients listed as 'other' those are the inert parts to keep the concentrations down to where they want them. So long as no other chemical is specifically listed then its OK.

Materials needed:

  • 1 bag of 73% Calcium Hypochlorite Pool Shock
  • A couple 5 gallon buckets
  • A funnel
  • A couple empty bleach containers

Make bleach

1 heaping teaspoon of pool shock makes 2 gallons of bleach

  • Place 2 gallons of water into a 5 gallon bucket
  • Place 1 heaping *teaspoon* of pool shock into bucket
  • Stir into solution thoroughly
  • Place funnel into empty 1 gallon bleach container
  • Pour 1 gallon out of bucket into bleach container
  • Repeat for other bleach container

Now you have made two gallons of normal household bleach that you can use for anything you would normally use bleach for like cleaning, disinfecting etc.

A 1-pound pag of calcium hypochlorite in granular form will treat up to 10,000 gallons of drinking water
