Scents in the Air Bad?

[MoeReefer]

i would try and stay away from anything that may harm your fish tank. if it harms the life in the tank, then im sure it isnt to good for you either. i just dont like the idea of spraying any kind of cented unnatural substance into the air i breath. if i wanted to breath carcinogens then i would just start smokin agian, at least i would enjoy it more. man i used to love smokin.

cheers
