It is best to buy Calcium Hypochlorite (Pool Shock) at Wal-Mart for $24 for 5 1-pound bags. It only takes a hair of the stuff to treat water. Clorox goes bad within 6 months, but this stuff is good for a long time.
Google for Calcium Hypochlorite. 1 pound treats about 10,000 gallons for drinking water. (If I remember that right!)
P.S. Calcium Hypochlorite can also be used to treat water for cleaning and wiping down surfaces. Unless you buy boatloads of cleaning supplies at a pretty significant cost, this stuff will do nicely to wipe down surfaces. Just concentrate it more than you would for drinking water. There are recipes out there for this.
Thanks, that is exactly what I have, just in a lower concentration than other websites specify. I still think it will work fine, once adjusted for its concentration.
