Let your common sense guide you. The pool store stuff is HYPE. Once the "shock" dissolves, it puts chlorine into the water. Chlorine is chlorine is chlorine! There is NO difference in how fast it disapates once it's disolved into the water. Testing your chlorine levels is the best way to learn what to expect.

If your water is fine, shocking isn't necessary. You shock when your water isn't fine to prevent it getting worse.
