This journal entry is a continuation of my series of entries on disinfection of drinking water. Please read the following linked articles first, Introduction to Disinfection and Disinfection with Sodium Hypochlorite. I have covered a lot of background information already, which you will need to fully understand this journal entry. Go ahead, Ill wait.
Calcium Hypochlorite, Ca(OCl)₂ is a solid chemical used as a disinfectant and bleaching agent. It is used to store chlorine for long periods of time without having to resort to chlorine gas, which is extremely dangerous if not handled properly. If stored is a room temperature environment away from moisture, temperature extremes and direct sunlight, calcium hypochlorite can last up to a year without serious degradation. Beyond a year the chemical will become weaker with time.
Calcium hypochlorite is very similar to sodium hypochlorite. The biggest difference is in the appearance. Calcium hypo is a white powder and sodium hypo is a yellow liquid. Sodium hypochlorite is a liquid and can be added directly to water for disinfection. Calcium hypochlorite on the other hand, needs to be mixed into solution first. Then added to the water for disinfection.

No it doesn't. Nor did I claim it did. It says, as I pointed out, to add over 1.5 lbs. What does this (from your article) say?

Can I get on your ping survival list?
(I cannot use private posting apparently, sorry for the public one. Anyone know when I can use the private method?)
You have been added.
Is that the correct recipe??granules |
A cup of sugar (8 oz volume) weighs about 5 oz.

To sanitize water.... You'll need to use some of that solution to sanitize the water. 50 ppm is about right, and can be tested for.
Did you miss that step?

Thanks, no, I didn't miss that step. The recipe given for the disinfecting solution is way off. |
It's the formula for making the kind of stuff you buy in the store (3 times stronger, though). that you mix with water to make a disinfecting solution.
If you have a correct recipe, I'd love to see it. Perhaps we could step through it together.

Teaspoons and 'about' and liters is a little confusing for a simple cook like me.
