Sun Coast Pool Chemical has serviced my pool for about 3 years. I think they are the ""go-to"" people for ANY answers regarding pool issues, internal and external. They are the PROS. They have been nothing short of efficient, on time and great diagnosticians of any sort of problem. I HIGHLY recommend them to anyone considering a switch over or looking for a new pool service. I am most pleased with them as experts in their field and they are really good folks too. J. Dearborn, Fort Myers.
