Great thread.

From personal experience I would like to say if you even suspect that something in your tank is affecting you, check it out with a doctor. Use as many precautions as you can when dealing with your tank, even though you don't show any allerges today doesn't mean you'll be fine tomorrow. I wasn't allergic to very many things before I got my tank, but within a year I developed hypersensitivities and then allergies to substances in my tank.

A little precaution goes a long way, this isn't a toy we are dealing with, but highly evolved animals who have survived on this planet longer then we have!
