Stuffed Up

[sumpfinfishe]

Hi All

Just wondering if anyone else keeps there reeftank's in there bedrooms.
Reason being- as the weather has been cooler outside, and with the house being warmer inside-I'm waking up in the mornings to a stuffed up nose. Now I know this could be alot of different things like smoking, allergies, or a cold perhaps. However during the spring and summer my bedroom window is always wide open and now it's always closed.

So my question is could be reef related, either from evaporation or maybe from gases produced by the skimmer
Any thoughts would be appreaciated-cheers Rich
