Humidity vs electronics?

[Brent Shaver]

With having two tanks going, (only one SW) in a living room would this possibly case an issue with home electronics?
Reason I ask is because I lived on the Gulf Coast in Texas for a couple years and pretty much every TV, radio and even toaster had a best shelf life of a year. Between the humidity and salt air ate the circuts.

Has anyone ever had this issue, or would the levels be to low to be concerned? I dont want to fry my plazma or any other electronic toys..
