Yup.
Unless your CC is rising, or you are losing chlorine between sundown and sunup, or your water starts to look hazy, there's really no reason to shock, and certainly not weekly.
I shock my pool after I've had a couple of very busy bather load days, especially if there are very young kids or suspected pee'ers in the pool, and I usually shock it after hurricane-generated storms. Otherwise, save the chlorine!!
