I have a vinyl lined doughboy pool that is oval and 6000 gallons and currently using baquacil. I am converting to chlorine and plan on emptying the pool, cleaning as I go, and then refilling it right away. I have a 1" pvc line dedicated to the pool for filling so it will fill rather quickly compared to a garden hose. Am I safe to just empty it using the vacuum hose and pumping to waste and then filling right away or do I risk damaging the liner exposing it to sunlight (suppose to be 85 and sunny tomorrow). I am guessing it is completely okay, but better safe than sorry by asking here first.
