A tablespoon is good. My guess is that's a bunch of packets -- at least 6, probably closer to 10 -- but it is for 5 full gallons of beer. Just measure the packets out.
I added the acid blend at the same time. I've heard of some folks using lemon juice instead & I suspect this would work fine, though I have a hard time knowing how much to use. I'm guessing the equivalent to the juice from one large lemon would be nice for 5 gallons. The brightness from the acid blend did more, I think, than the sweetner.
