I called another company, beacuse they were closer, to come test my water of my pool. The other company came out and tested my water and had me buy new chemicals to add to fix the problem. A day later, I still had issues with my water. The other company then came back out and put in chemicals to reverse what they had me do the day before. Finally, I'd had enough! I called Bob and he was able to help me over the phone! He was able to fix my problem without coming to my location. Thanks!
