Osmotic Pressue?

[Tom]

Now here is a question for everyone.

Do chemicals such as dechlorinators add to the overall osmotic pressure in
the aquarium? If so would(could) this cause any sort of stress on the fish?

Food for thought.

Would salt do this as well?

from what i heard salt is suposed to help realive osmotic preassure on fish, but then agaien theres other thigns it does aswell. Iv neevr heard of this being caused by other chemicles, but ya never kno. I woudl doubt it peronaly.
