Ideal fan to vent a fishroom outside

[lastlight]

This is for the new tank. The tank and room behind it are essentially sealed off from the house. I am running a fresh air feed pipe into the room even though my condo is old and leaks like a sieve.

I don't really like the idea of the bathroom fan as you're garanteed to have some of that moist salty air escape the enclosure itself and find it's way into the ceiling above the room. At least the inline fans are mounted inside the room itself...
