My husband and I have a second home in Tucson which we bought 3 years ago. We have a pool service handling the care of the pool as we have never had a pool and we did not live at this residence full time. We have had relatively poor service over the past year. We are uncertain if the pool guy comes weekly. (Doubtful that he shows up weekly). We had our pool resurfaced last fall and the chemical guy referred us to your website. Our pool is 20,000- 25,000 gallons. Our plan is to learn enough to maintain the pool ourselves instead of relying on questionable service once we are at this house for longer periods of time. I have browsed through the website a bit but plan on taking all the classes, so I become proficient in maintaining the pool. We also are considering a cover for the pool when we are not in residence. I am excited to learn a lot and I understand that the people here are very helpful.
