Hi, I am a new pool owner trying to figure things out. The site is very helpful. I have two questions and some pictures.
1. I have two skimmers that have shut off valves and a main that has no shut off. Should I always keep both skimmers wide open all the time?
2. I have a polaris pool cleaner. There are ports beneath each skimmer to plug it in and a booster pump that I turn on to operate it. When running that should I shut off the opposite skimmer valve?
Thanks in advance for your help.
