I am so ready to start doing stuff with my pool already...but we are still getting into the freezing temps at night, but daytime is in the upper 40's to mid 70's most days right now...I am thinking of just hooking up my pump/filter and letting my robot get started on the cleanup of dirt on the bottom of the pool after I give it a decent brushing to get things stirred up a bit. and then maybe start dialing in my water balance so that when i am ready to turn on the heat pump, i will be ahead of the game already...if I leave the pump/filter running at night, will that keep things from freezing? i think we would need sustained freezing temps and still water to be an issue, but don't want to risk it. thoughts?
