Came back to Phoenix unexpectedly and our pool was a deep, murky green. We had been using this service for several years. They didn't expect us to be returning to Phoenix at this time. I called and was given the excuse that some flowers fell into the pool and that the heat rose in Phoenix. I asked when they are coming out - they did come and the pool is now a deep, murky blue in less than 24 hours. Very disappointed with this service and was given "attitude" on the phone.
