  1.0 out of 5 stars Expensive and does not work.

  Verified Purchase

  I purchased this because of the positive reviews. This is the first year I tried this, and my swim spa became cloudy, and a ring scum developed around the waterline. I am a clean freak, and I test my water daily and I had to stop using this because the water quality went whacky.
