Any problems from the fumes that can be causing my tanks to cloud up?
I doubt it!

I'm an artist.....I work in the same room as my tank (oh no)
Because I live in an open loft I can't close off the tank.
It's not the best thing for a tank to be in a room with fumes
(I have walls of windows I can open if it gets bad), But for me
it sometimes can't be avoided.:shhh:
I use adhesives incaustics, spirits,etc.,
with no problems.
If fumes could cloud your water, my tank would be opaque!
You didn't use any kind of aerosol adhesive, causing a mist that could have fallen into the water - did you?
I'd look for another reason- get more responses:grouphug:
What would be my best course of action?
I would at least do a partial water change and, if your not already...run some carbon.
