Water Hardness Test Strips,Upgraded 100ct,0-425 mg/L, HoneForest Hard Water Test Kit, Testing Total Hardness of Water Softener, Drinking Water Quality, Pool Water,etc

I recently purchased these strips and I have been impressed with their accuracy and ease-of-use. I recently had a water-softener installed and they accurately detected the hardness of water in my home which allowed me to properly adjust the salt-usage in my water-softener. This allows me to efficiently use salt to clean the system and ultimately save costs. The strips now accurate detect that my home-water is no longer showing hardness in my water which allows me to determine that my softener is continuing to work properly.

Needed to test my water to find out how hard it was so that I could set my dishwasher water softener settings. Had my answer within minutes. It really is as easy as running one of the strips in the bottle under your water for 2 seconds, shaking off the extra water, wait 40 seconds and match it to the correct color on the bottle.Would certainly recommend this product.

The test strips are easy to use. It takes about 1 minute to complete the process. I can't address accuracy because I don't have any way to verify if the results are accurate. My results were in between 2 colors so I calculated what the gpg/ppm would be. I bought the kit to test my water for a new dishwasher. I have to enter a hardness number in the dishwasher Mmol/L so I contacted HoneForest by email about a conversion from gpg/ppm to Mmol/L. They responded very quickly.

Noticed that my dishes and laundry wasn't as clean as normal. I have a Water Softener, so I figured it couldn't have been hard water, but ran the regenerate on my water softener thinking I was good. No improvement. Purchased these strips to test 'with' and 'without' my water softener. Found that my water softener was not working. Ended up replacing it as it was pretty old.Plus, I brew beer and it good to know if I have hard or soft water for different beer styles.

I believe the test strips I received are defective. After getting a result that didn’t match the scale on the bottle while testing spa water, I immediately tried three additional strips in other water of known approximate hardness to gauge the strips’ accuracy. Provided with this review is a photo showing three test strips used on three separate water samples.The photo does not render the color precisely the way it appears in person, unfortunately. The actual colors in person appear less green and not as dark as pictured.The leftmost strip was used in pure distilled water. The center strip was used in municipal tap water without additional treatment (which averaged appx 80ppm TH as CaCO3 per municipal water reports for last month). The rightmost strip was used on treated spa water which is typically about 180ppm TH after treatment.The three samples were submerged simultaneously for 2 seconds each and the photo was taken approximately 40 seconds after being removed from the water sample. The resulting color appears to be essentially the same for the three different samples and doesn’t align well with any of the colors on the provided scale. The leftmost sample appears slightly more green in person than the other two.The package of test strips did not appear damaged prior to opening. The factory seal was intact. The bottle was opened for the first time immediately prior to first use. The desiccant packet was not removed. There was no moisture intrusion to the bottle. The bottle was kept tightly sealed prior to the second test which was approximately 10 minutes after the first test. Strips were used as directed. I’m left to assume that the strips themeselves are defective and found them unsuitable for my needs.

I found it difficult to read the color scale on these strips and get an accurate hardness reading. When you set your water softener you would like to know the hardness pretty accurate so you don't use too much or too little salt. I wound up buying a test kit from Hach on Amazon (20 bucks). This kit gives you 1 grain per gallon accuracy. Turns out my water is very hard, checking in at 16 grains per gallon. (10 is considered very hard). With the test strips there was no way I could tell if it was 10 or 16. If you need accuracy I would try a different kit.

These seem to be accurate. I had to hard a lot of calcium hardness to my hot tub because I have to fill with soft water. My well water has a lot of iron so I can't use hard water. The readings I get from these seem to match my calculations of ppm as I add it.

These strips measure only calcium chloride, the largest hardness component in hard water. There are other hard elements in most water, like magnesium and sometimes a little iron. Therefore the reading from the strip won't be the measure of everything that makes your water hard. Set your softener a few grains higher than the strip reports.My batch didn't like totally soft (or distilled) water. It would read close to, but never at, zero grains. But half a grain is well within the error range for all test strips. That's just how the chemistry works for test strips.My experience with only one of these, but with many Hach (generally AquaChek), suggests this brand is just as good. The result colors are different for the two products, and I think this brand is easier to distinguish between the lower scale readings.
