Mixing pool chemicals

[nepsa]

I am going to shock the pool with bleach and then (within 15 minutes) place the tablets in the skimmer.

If you just make sure the bleach is mixed into the water first, then that will be fine. So if you add your bleach via skimmer, give it 10-15 minutes or so to circulate before adding the tabs. If you add it via return stream, you could go ahead and put the tabs in the skimmer and you shouldn't have any problems.
