These guys are the worst. I'm not sure if they don't know what they're doing or they just don't care. They take NO pride in their work. They say they've serviced your pool but the hot tub & filter are filthy later that same day? They tell you the only way to get your pool "balanced" is to drain it & start over. A month later the walls are covered with algae, and the calcium scum line is the worst it has ever been (even though I paid extra for a so called product that would clean it). I returned home from a long business trip just days after he was scheduled to service the pool. The algae spots were worse & the water level was down 4 inches. How do you not fix that. It their job after all. It was definitely the last straw. I looked at my original picture of how all the levers were supposed to be & he had moved them all backwards & wrong side up. I took a sample of water to the pool supply place for testing. Every chemical that can be controlled was completely off. There was NOT a drop of chlorine, NO Cyanuric acid (Which should have been added when the new water went in), the PH was all over the place & the phosphates were off the chart. Do not let these people near your pool. They give the business a bad name
