Review on Industrial Test Systems 481340 Check by Shedrick Roach

Got these test strips for our pool and couldn't figure out the values. The colors just never change. Received a glass of pool water today (green cloudy water today) and a glass of filtered water - both tested the same way at the same time - SAME ACCURATE READING! Just my opinion - readings never change - regardless of the condition of the water in the pool. I wish I had never spent money on it. Save your money - buy something that actually works. - Not sure if this will work but has positive reviews and hopefully a higher price will buy your better quality. Do not buy this test.
