We just had our inground pool completed about 4 weeks ago. The pool is open so that we can brush the plaster as it cures. The PCC 2000 filter system runs 24x7. We have another 2 weeks (minimum) of brushing recommended by our pool company. We live in Northern Virginia where the temperature has been 50 - 60 during the day (now in Dec) and 30's at night. The folks at our pool servicing company said we may want to leave the pool open through the winter instead of closing it up and reopening in 3/4 months. They said as long as there is no deep freeze and the filter stays on continously we shouldn't have a problem. My question is what defines a deep freeze? And is this really safe on something I just spent a lot of money on?
