I was glad to find this website/group, and hope to get and give help where it's needed. I have a 20 x 40 inground gunite pool that's 20 years old. I'm in the process of replacing my old pump and filter, more information when the installation is done. There's an old Polaris robot for cleaning and I have an automatic cover that has been worth its weight in gold over the years. Hopefully the weather will be more pool friendly this year here in Calvert County Maryland.
