You probably can use the SWG if you calculate the runtime carefully. Many folks have oversize SWG's that can raise the Fc by a lot in a few hours.
Don't put tablets in your skimmer as when the pump is off acidic water will accumulate int he skimmer and a slug of acid water will pass through your equipment when the pump turns on. Use a floater for tablets. With that said tablets doesn't give you much control over the FC created.
The key thing is you want to control the slow rise of FC and the SWG or tablets does not give you the control liquid chlorine dosing does.
Okay, that makes sense. My SWG is on a separate switch so I can run it for say an hour, and recheck my FC...leaving the filter running as needed (continuous I believe?) Goal is to bring FC back to safe level...but SLOWLY...correct?
One other question...I did have to pickup some stuff at the pool store and they asked what I was doing....I told them, and then got the "you have to keep the FC down to zero for 10 days after the treatment". Where does that come from? I heard that from another PL as well. Every AA treatment report I've read on here said they started bringing up the FC level 24-48 hours after doing the AA treatment.
