They are totally incompetent. All they did was add chemicals once a week. I had algae growing on the sides every time I checked the pool. I had a leak in the Polaris booster pump, so I shut it off until I could repair the pump. The pool person turned it back on without opening the suction valve and ruined the pump. When we told the owner about this he said that they weren't psychic and wouldn't know that. That is basic operating of a pool system. If you build pools, service pools, that is something you should know. They sure don't know anything about pools and I wouldn't want they building one for me.
