I'll have to remember this idea. I usually remember, but I have forgotten it on occasion.
To the OP, I don't think it would hurt anything to add it at the beginning of the whirlpool if you forgot to add it during the boil. I would suggest crushing it up a bit as it might not fully dissolve if you throw the whole tablet in there.
