I inherited an AG pool, oval 26x15' when I moved into my house 3 years ago. The pool had called into disrepair and I essentially had a swamp in there, filled with algae, bugs, and frogs. Well the pool has now been completely overhauled. New liner was placed this week, and I have now filled the pool to just below the skimmer and return. I want to keep the water clear for next summer. Problem is I'm in NY and it is essentially pool closing time. The guy who repaired the pool told me to just get a closing kit and then cover the pool and recommended not connecting to filter until next season. Is this sound advice or should I be balancing chemicals before winterizing? And should I be running the filter or is it ok to leave it until next season? I had gotten a new filter and it is still in the box. TIA
