@BigDave - Yes, it was a white slurry solution. I let it sit in the bucket for a couple of hours and gave it a stir about ever 15 minutes. By the time I threw it in the pool the majority had dissolved. Just went out and checked on it and I'd say there's maybe 1/4 cup left sitting on the bottom so I got it to dissolve pretty quickly.

Just checked pH and Cl and I'm sitting at Cl 5 and pH 7.5. Yesterday I probably but in about 2.5 quarts of bleach.

I found the copper ionizer and I'm trying to figure out how to disconnect. I'll stick with bleach for a couple of weeks, we bought plenty. Yes, ordered the K-2006. Thanks for your input!
