Paul is a professional. My wife and I bought a new home and it has a pond in the front yard. He met me for a free consultation and gave me an overview of my pond's system. It needed to be cleaned so he came back yesterday and cleaned it (six hours) and it looks great. He was on time, friendly and he really knows his stuff. Highly recommended. he also did not try to sell me on monthly services, he even showed me the proper way to clean it. My goldfish are happy!
