When a level of 0.3 ppm is reached, a good pool shocking is indicated. Shocking the pool to a level that is 100x greater than your chloramine is effective at chloramine removal. For a level at 0.3 ppm CAC, add enough chlorine to reach a level of 30 ppm in the pool. Chlorine is a great algaecide, I like to say.
The moral of the story is that you have to test your pool to know when to shock. Shocking monthly, or even weekly is overkill in many cases. Test visually for algae and cloudiness, and test your pool (and especially your spa) for bacteria with these inexpensive bacteria test strips.
