Until owning my own pool this year, I had only swam in other people's pools (probably poorly maintained) and commercial pools. They all had a typically pungent aroma of chlorine, those dreaded combined chlorines. Now that I have a well balanced pool of my own, I've taken to... taking in it's smell. When I'm in the pool, I get a slight hint of that chlorine/bleach smell but almost nothing. When patrolling my pool deck with the skimmer net for rogue maple seeds and doomed insects I smell almost nothing. Almost. The only way I can describe it is a faint hint of something similar to antifreeze. I can't help but remember the jugs of RV antifreeze that were in the skimmer buckets when I opened the pool for the first time. The lines were properly winterized and obviously some of that antifreeze went in my pool from the lines when I opened. Could I possibly be still smelling it? It's an extremely faint aroma but that's all that comes to mind when I smell it.
What do your pools smell like? Anyone else who has to completely winterize in a colder climate have a similar take?
