Review: Excellent Kit~ Well Worth the Money! - This kit works great! My daughter has been complaining that her hair doesn't feel clean after shampooing. She said she needs a different shampoo. Then it dawned on me that my hair has been feeling the same way. I told my husband that I think we have hard water and something is wrong with our water softener. He replied, "No, our water is not hard, it is soft" Hmmmm A friend stopped by last week and said, "what did you do to your hair??? It is lighter than I have ever seen it and it looks like you have Orange highlights!!" I had not done anything, but I did notice that my hair color was a bit different lately (I am a brunette) and didn't know why. She looked closer and felt the ends of my hair and said, "you have hard water". So, I went on desertcart to order the testing strips, but read the many reviews and finally decided this kit would be more accurate than the strips. I received it the next day. Sure enough, it took over 20 drops for the mixture to turn blue. Yep, our water is HARD! The company that installed our water softener came out today. The kit he brought with him was almost identical to this one. I watched him and it took 25 drops for the water to turn blue~ the softener is not working at all. He took the unit with him to do repairs. " Rebed & Valve Repair". The parts are under warranty, so we just have to pay for service & labor charges. He will be back Friday with the repaired water softener. The bad news: The labor and service charge is going to be over $550!! Wow, that seems high for the Service Charge and Labor Only!! Ugh :( However, I do highly recommend this test kit. Instructions on the box were clear and easy to follow. Maybe if we had bought this test earlier to use on occasion, we could saved some money in repairs. After it is fixed, I will think I will continue to use this kit on a Monthly basis to make sure the softener continues to be working as it should. ;).
Review: Good Product - I've worked in Municipal water treatment for 30 years, and I've used them all. This is a good product, easy to use. Price is reasonable. Would have many many tests in this kit.

## Questions & Answers

**Q: Okay, what am I doing wrong.  The water was blue, not pink when I added the microspoon of  chemical, no drops added.**
A: It means your water is soft already. If it was pink, then however many drops you add to turn it blue, thats how many grains hard your water is. Since you did not have to add any drops that means your water is 0 grains hard.

**Q: What is the hardness range for this test kit? Thanks**
A: You can always dilute your sample to extend the range.  Dilute with soft water (distilled, clean rain water, or previously softened water).  Just check that the soft water tests for zero hardness before using it.  1:1 dilution would double your range.  1:9 would extend the range by a factor of 10.  A cheap drugstore syringe could be used for dilutions if you don't want to eyeball it.

**Q: Does this kit come with the test tube and mixing bottle like the one from Hach?**
A: Hach's part number 145300 does come with the measuring tube PN43800 and Glass Bottle PN 43900

**Q: Why would the color of soft water turn blue as soon as the indicator is added to the sample, without any additionof the titrant?**
A: This happens normally, if the water is soft (zero grains of harness). The grains of hardness is the number of drops of titrant you have to add to get the water to turn blue. If you do not have to add any drops of titrant, then you have zero grains!
