Alkaline, Tap, and Drinking Water pH Test Liquid wht(100-125 Tests) 0.50 Fl Oz (Bigger Bottle) by A2O Water - Made in USA

Works great! It's a multiple use bottle, so I can test several times without having to buy a new kit!

This ph tester does exactly what it sets out to do. With just a couple of drops I am able to quickly gauge how acidic or alkaline my water is.Where I live we have hard (acidic) water so we use a soda ash system to try to neutralize it. It was always guess work trying to figure out how much soda ash to pump into the water. Now with this product I test the water after making the solution so that I can better gauge how much soda ash to use the next time around.Honestly, it's hard to beat the ease of use and price of this product.

I like to test the ph level of my drinking water.These drops work great

The media could not be loaded. I tested the tap water at my home and tested water that was ran through a Britta water filter. The pH drops appear to work well as the tap water was more blue and the filtered water turned green.

I used this product to test my tap water and several different manufacturers of bottled water. Some of them were stretching the truth with claims of 9.4 pH. I recommend this product.

These drops are excellent for neutral to moderately high pH. Not so good for low (acidic) pH, below 7.0.

Works well to test my water and ensure my whole house neutralizer was working. Much better than paper strips (which are near useless for this purpose). Not quite as accurate as the Hach set (as requires comparison to the printed label, thus subject to some variation depending on lighting etc) but a fraction of the price. Recommended.

Product itself seemed to work fine for a Science project.Delivery not so much. We ordered in advance and it was delayed/lost/never arrived.Arrived later than expected.Order way in advance if needing just in case.
