Humidex - it works

[TheReefGeek]

I dont think you would need a fan that can do the whole house, as long as you can locate the fan near the source of the humidity. In my case I will locate my bathroom fan right in my fishroom, and if the fan can keep the humidity down in the fishroom, I assume the rest of the house will be fine.

If you have multiple tanks is locations throughout the house, it could be different.
