Not sure if this is such a good idea. It all depends on the current pH level. I find adding a puck to the skimmer rapidly decreases the pH and the puck might only last a day in the skimmer anyway. This won't help much because it won't do anything for the CL level later on in the week.

I'd just use bleach to bring it up to shock level and not have to worry about the pH.
