I just scanned over your title and I thought you were talking about:
Terrigen Mist- the mists used to create the powers of the Inhumans. My first thought was, how did he get that in real life? Followed by, how quickly can I get to his house? Then my brain shifted out of neutral. So, good luck on your tank misting, not on your creating Inhuman's powers.
I am not in theory opposed to Terrigen misting the aquariums.
