So far - so great! We moved into a home a year ago and have been struggling with our original pool person to keep the water clear and blue. After getting very tired, we invited our neighbor's pool person - Herman - over to take a look. He kindly came over, looked at the pool, gave advice and even took the time to clear it up that day! He identified a number of things that were contributing to the problem and how the "bandaid" being used by our current pool person was not going to help. He was wonderful.
