Review: Amazing product/works GREAT! - This stuff is amazing!! I have an old well and very hard water. I treated my well as directed, and the smell was gone!! The hard water let up a lot too!! I'm going to do it again this spring. You have to flush it with your water hose, so it cannot be done in the winter in a cold environment. Make sure you turn the water off to your hot water heater or it will ruin it. I read all the reviews and someone had mentioned that. It's pure chlorine, so wait to turn the water to your hot water heater back on after completing the flushing process. *make sure you read and follow the directions!!*
Review: Great product. Works wonders! - This worked so good for our well water. Our water smelled so bad but now it doesn’t anymore thanks to this wonderful product! It taste much better when brushing my teeth. My teeth feel clean now. My skin feels better and baths are more comfortable in cleaner water. I was about to go stay in a hotel because our water was so gross but thanks to this product I don’t have to now. My husband wouldn’t let me anyway. But I could if I wanted to. lol

## Questions & Answers

**Q: Instructions on shocking the well**
A: Instructions are provided in every package. They are also available at http://betterwaterind.com/wellsafe.html

**Q: How long will this keep the sulfur smell at bay?**
A: Chlorine will kill sulfate producing bacteria which often causes the rotten egg odor along with other bacteria. Customers who use this product report it completely clears up the smell for anywhere from one week to a year. Most customers say the spring and fall treatment keeps their well odor-free.

**Q: what are the active ingredients and at what percentage for each?**
A: These are listed on the bottles as Calcium Hypochlorite: 73%. Also, this product is often used with iron-laden water. It does oxidize the iron in your water which is a rust color. When flushing the excess chlorine from the well, the oxidized iron is typically also flushed. Many customers use this product to reduce iron buildup.

**Q: How many gallons will one kit treat?  My well is 405’ deep with the water level at 34’.  That gives a column of about 562 gallons in a 6” bore.**
A: To produce a 100-ppm chlorine concentration, use 2 oz. sanitizer pellets or granules for each 100 gallons of water in the system. (2oz. granules = 56 Pellets).  The bottles have 8oz each for a total of 16oz.  You would need 11.2oz to treat 562 gals.  5.6oz of each (granules and pellets).  So one pack would treat your well.
