Humidity Control?

[untamed]

I'll chime in a bit here since I've been looking into this closely as I plan my 360 installation.

The humidex basically a combination of a vent fan and a humidistat that turns the fan on/off based on humidity. It vents out of the house only, and depends on "leaks" in the house to bring new air in. That would be a concern in a very new, tight house due to negative pressure.

A good vent fan to the exterior attached to a humidistat would do about the same thing. I would guess it would cost less, but require a bit of DIY.

Finally, the last thing I'll mention is that it would be good to control the space where the humidity accumulates. If you can get good containment of the tank and fish room, you have a smaller air volume to deal with.
