I just finished my liner install and began filling the pool with city water. The pool is a vinyl inground about 20,000 gallons. I live in Michigan and the weather is dropping in temperature. I have all the plumbing ran to the pad but was not planning to hookup any of the mechanical components. I.e the pentair Inteliflow pumps. What can I do to prepare my newly filled pool for winter as far as treating it with chemicals if that is what is recommended from all of you without having a pump to circulate the chemicals? I did order today the TF-100 test kit and the Taylor K-1766 salt test kit as I'm planning to do a salt water system pool. I have not performed any tests as I'm waiting on the kits to arrive. My reasoning for no mechanicals is simple....I'm just out of time until spring and don't want to put all the shinny new stuff out in the snow. Lol.
