Believe me Mr. Salty, I know more about nicotine and cigarettes than you could shake a cancerstick at. Unfortunately, as you know, it takes more than knowledge to kick the habit. I do know that many of the chemicals suspended in cigarette smoke will absorb into tap water. I would suspect that saltwater is slightly less absorbtive. I'm relieved to hear that you've found that the smoke has no effect on the tank's inhabitants.
