Oh...I wasn't clear. It's the filter/pump combo. I'm running it about 8 hours a day with the SWG on for 4 hours. I bought the taylor kit last summer (after advise from you all)

Last year I filled the pool with well water and I think that was part of my problem. This year I used my city water (which I'm sure I'll see on my next bill) and so far it seems to have been a good decision.

Here's to hoping this will be a better summer. I'm going to stay ahead of the game.
