I'm pretty sure that they had the pucks in them and were stored outside near the pool pump. I didn't want to store them in my garage due to concerns over the chlorine gas corroding things in my garage. This was probably around 20 years ago when I had the house with the pool (and was not using a pool service). Eventually I switched to a pool service and after that, switched to a house that does not have a pool. When the pool water temperature is in the 90s, it's just not that refreshing to take a dip, so I never used it.
