Good product - colors are close
Good testing strip - but colors are close to each other. So you have to really pay attention to the shades and sometimes test again to make sure your reading the levels well. I will buy again.

Just dip an AquaChek Red / Bromine 4-in-1 Test Strip in your spa (hot tub) or pool for one second and remove it immediately. You get test results in seconds. It couldn't be easier!
To keep your spa at its best, test the water before each use. Test your pool at each end, at least twice a week. It's also a good idea to write down your results each time you test, so you can track changes over time.
