Walmart bleach it is. Will refresh my memory on the overnight. I know I read it on here last year.
and I am correct re pH only using the K-1000?

To lower TA you have to use acid which also lowers pH. That's why it only says, "To lower TA you reduce pH to 7.0-7.2 with acid and then aerate to increase pH." That's the acid/aeration" method as seen on the Pool School - Lower Total Alkalinity page.
