Water Hardness Test Kit-150 Strips Water Quality Testing 0-425 ppm

Works week and good price

works

My pool water was way too hard and using these strips I was able to monitor the level as I removed the calcium. I installed a water softener in the pool and the test strips let me control what was going on.

The instructions should be updated that the strips need to be read at exactly 30 seconds. If you wait even 1-2 minutes, most of the color changes back to green and the edges become even more orange (see test strip on the left in the picture). So you need to set your timer and take a picture at exactly 30 seconds.

This is your average water testing stripe.

Easy to use, water hardness test kit. The kit works well provided the steps are followed according to the instructions. The test results completed as was expected. I am pleased with the kit overall.

Great for testing drinking water. Water is clearer now. These are not great for testing pool water. Neighbor was using these. I explained how these are used. His pool looks good now. Bought a pool kit.

Perhaps I have a faulty batch, but these are impossible to read. I kept thinking my water softener was not working and got these to see if it was kicking on the recycle like it should. I've done 3 tests and not one come close to matching a color on the legend. I have no clue how you are supposed to actually tell from this what the hardness is. I reached out to a neighbor who had a different kind of kit where you put little scoops of a solution into a test tube and it is super accurate and easy to determine what your water hardness is. This is inexpensive, but far as I can tell it doesn't actually work.

This is a simple product that does exactly as advertised. No more no less and seems accurate.

très bien

Tested my water to make sure the water softener is working correctly as the salt tank sometimes forms a salt bridge. This product gave me an answer in 30 seconds.
