If you are still concerned have a fresh batch of salt mix ready to go and in 12 hours do a waterchange to refresh the water and by then even at 12 hours the silicone should be fine it's not like you are re sealing the whole tank and have massive amounts of silicone all your using is a small dab to hold a hook.that little amount shouldn't bother anything even after 3 hours no more than using two part epoxy and crazy glue to glue frags

Would carbon take out any of the silicone fumes (or whatever you call the underwater equivalent)?

I thought carbon takes out a lot of "stuff"
When silicone cures it gives off acetic acid, and if I remember correctly that is vinegar.
I read somewhere where people were dosing vinegar, as a carbon source, like dosing vodka
I'm sure curing silicone also releases other chemicals, but your carbon filter should take these out.
IMHO
