We plan to hook up the equipment this weekend. We're in east central PA and probably have temps similar to yours. I want to be able to run the pump and mix in bleach to stay ahead of the greening that begins at around 54F water temperature and I definitely want to catch the pollen when it starts dropping on the pool. Most likely the pump won't be on every day yet though if we get a freeze, I'll run it at night. It won't be ready for people to swim in until mid-May (if you're very brave) but the dogs can get in now, the sooner, the better, they say.
