My tank has a problem with condensation on all of the windows. I'm wondering if it is necessarily due to moisture trapped in or under the carpeting (perhaps in the doors themselves?), or if poor weatherstripping seals could contribute to this condition. I don't seem to have any active leaks, although the front carpet was quite damp when I bought it. if anyone else has been there and fixed it, or understands this phenomenon in more depth I would appreciate it.
