Aquarium humidity

[Dan Friday]

how large can I go with tank before humidity becomes a problem ?

I currently have a @ 68G tank with open top and no issues of humidity. Previously I have a 90G with topper and the humidity was noticeable in my small den. I use a ceiling fan in my den and it helps allot with the humidity. So I believe a 90G or above, you'll start noticing humidity. Hope that helps you.

I have a 90 gallon DT on the first floor of our two story house and the only issue I have with humidity is in the winter.....on very cold days. On these cold days I get condensation on all the windows....lower edge of the sash (Anderson windows). In addition, one especially cold year, the one upstairs bedroom (coldest room in the house) actually starting getting condensation on the walls (old plaster walls). When this started happening, I put a dehumidifier in that room. Otherwise, I don't do anything except on an occasion dry off the window sashes with an old towel.

I just recently bought a dehumidifier for my house. I have an open top 90g in an 1100 sq ft house, and I've always got moisture/mildew at all my windows. First two days of running it, I was emptying out the 70 pint container twice a day. I was really surprised how much moisture I had in the air. A week in though, and it goes a few days without filling up.
