No, I'm gonna put a heaping teaspoon into 2 gallons and put it on a shelf. For the $14 plus shiping for 30 tablets will make 7.5 gallons of water which will last my family of 6 plus their spouses about a day. So if I want to say last 6 months $15 x 180 days = $2700. I'll spend the $5 on pool shock and the rest on food and other supplies. But to each their own.![]()
