I want to add that when contacted Island Pool Supply has been most helpful in answering many questions and spending way more time than it was worth TO them in helping me understand some of our pool problems. In Southern California, you have a twice weekly poolman, you pay less than 100 US (including chemicals) and you don't have half the problems with the variety of pools in San Pedro. Island Pool have solved several of our problems and I am very thankful for their business in San Pedro.
