DOES NOT WORK!
Idk if I got a bad batch, but i tested 3 different water brands and it turn them all blue. I than decided to test my sink water and the water in my toilet. Guess what, it turned both blue as well. After watching some more video reviews on this product. I saw one that also tested the water in their toilet, which also turned blue. So again idk if I got a bad batch but for now I give this a negative star. DOES NOT WORK AT ALL!
