AquaChek's Select test strips allow pool and spa owners to test their systems for free chlorine, total chlorine, total bromine, pH, total alkalinity, and cyanuric acid. Simply insert the test strip into the pool or spa water for 1 second, and several seconds later you have fast, accurate results. It is recommended that you test your spa before each use, and pools a minimum of twice per week, to get an accurate picture of the health of your system.

Love these test strips
I use these to get an estimate of free vs. combined chlorine. This strip was way more accurate than the cheaper ones I have tried. Worth the extra cost.
I'v tested the water several times and also checked it at the Pool store with their computer based testing system. The strips were spot on with the computer. I highly recommend them to everyone.
Highly accurate, easy to read, and comes with an excellent guide book on maintaining pool/spa chemistry.
