The most worthless company out there. I literally would not even use them if they offered to pay me the $30 it costs a week. Had black algae they came and did a chemical wash on it, came back within two weeks. They claim that it's in the plaster and what not. Worthless tech does not even see or notice it when it comes back, I had to call the office and let them know. They come back add a ton of chemicals and then it goes away and the tech should be monitoring chemicals weekly. Three weeks later comes back again. Call office they make promise after promise to call me back and will resolve. Never get a call back, never hear from them again. Tech comes and spends 6 minutes there if you're lucky, the only thing halfway productive the company has going for them is the email that you get when the finish the "service" and its just a reminder that you paid $30 and they didn't do anything to your pool other than skim some leaves. As soon as my 90 days was up I cancelled. Issue after issues... story after story from the people that work there. I don't even know how this company is still in business.
