Thanks, Sean. Regarding putting the salt in the pool, that's exactly what I did with good results. I put it in the deep end and used a brush to push it to the drain. In my case, the salt dissolved quickly.

I was noticing another benefit this morning: with the increased bouyancy in the water, my Polaris 380 can now climb walls like Spider-Man! It took no time for it to clean the pool. It just climbed and went all over the place. Before, it struggled to climb the walls in the deep end and I had to brush debris to the floor. Not anymore, though. I like it!
