I bought a home with an in ground salt water pool and live in the Memphis, TN area. I know next to nothing about pools other than what I have read over today on this site and others like it (so far this one is by far the best!). I had the water tested by a local pool company a few times and the water tested fine each time. I skim the pool, and there are no signs of anything other than clear water. My question is, the local pool company asked me if I was closing my pool for the winter, I was unsure so I scheduled it. When the techs came out to close the pool, they told me that closing was not necessary unless I wanted to waste $500 opening and closing. He suggested that I keep the water levels up and put a chlorine tab in the skimmer weekly since the salt cell will not produce chlorine. Our winters are mild, but we do get below freezing for a few weeks out of the year. I'm really hoping for some advice from here since I am getting conflicting information from the same company on what to do... If there is already a thread that I missed, I apologize in advance!
