Description

Water hardness is caused almost entirely by calcium and magnesium ions. Other di- and trivalent metals have a similar effect, but usually are not present in high enough concentration in potable waters to cause problems.

User reviews

These worked perfectly I tested my water and it was right on the button Unfortunately i still had to call culligan to fix the water softener
Excellent. Compare in sunlight for best color matching. Much easier to read than the other brand which turns from yellow to brown.
very accurate ! it helps a lot if you want to know if your water softener is really working and how good it is!
Worked perfectly, tested against a professional kit and results are accurate
They work great, I compared the results against a number of know water samples.
Great product. Gives me piece of mind when checking the hardness of my water.
Very easy to use. Great for testing water softness setting changes.
