"Shock" is a verb, not a noun. It just means to raise the chlorine level. You can just use bleach to shock with. No need to buy a separate product.

How much bleach to use depends on your volume. Here is a link to a bleach calculator that may be helpful. It actually has other calculators as well in the drop down menu in the upper left corner. http://pool9.net/bleach-calc/

Also, what kit did you order? Only an OTO and not the K2006?
