Check the pool school button on the top right, your shock value depends on what your CYA level is.
After you test CYA, check the CYA/Chlorine chart. Shocking is a process and the FC shock level is listed on the chart, shocking can be done with any form of chlorine. Most prefer liquid. Adding chlorine daily is considered maintenance (even though the products are most often labeled shock).
It will take some time to get accustomed to the test kit, but after you get some experience using it and spend time reading here your pool will be very simple to take care of!
