You can find 20 Mule Team Borax in the laundry aisle at Walmart and as far as bleach goes, you want plain, unscented household bleach. Generic is fine and is what most of us use.

You won't be able to buy a Taylor K-2006 test kit locally. It is only sold online. The test kit links in our signatures go to Amazon which sells the kit for a good price. Also, any purchases made from Amazon through those links earn a little money for the Pool Forum which helps keep us online.
