Hello my name is Spok2129. You may have noticed this is my first post so I am trying to get aquainted with you all. I have a question. I set-up a 20 gallon long in a very small bedroom. There wood bee no question except for this possible small problem. I have a expansive hi-fi (stereo, turntable, speakers of course) in the same room. Will this 20 gallon in my once again very small bedroom create too much humidity for the hi-fi? And the hi-fi puts out a crap-load of heat; would this be a problem or would the heater just adjust to it? Also I have a good heater (marineland). TIA
