Venting the Basement...Help me choose CFM

[Fizz71]

I know many of you don't venture off into the other forums. Please help me pick a vent for my fish room. I want to get something big enough, but not too big that the I waste electricity.

Here is the thread:

Oddly enough, I have no outside walls near the sump...they are about 10 feet away. It's hard to describe:

XXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXX
XXXXXXXXXXX0XXXXXX
XXX0MMMMMMMM0XXX
XXX0MMMMMMMM0XXX
XXX0MMMMMMMM0XXX

The X's are elevated crawlspace (starts 3ft off the ground goes up to 7ft), the 0's are walls (floor to ceiling) and the M's are where I have a full 7ft where the sump is.

If I put something in the wall to the outside it will be 10ft away with a wall in between it that the air would go around. I'm not sure how much that fan would help that far away which is why I was looking at a fantech inline so I can put the vent right over the sump and push it out the basement 10+ feet away.

Thanks for the post.

kevin,venting the room will work.you dont need to get it right on top of the sump to vent that small space with a decent fan like described

Want to minimize humidity and evap. eliminate the cool air contacting the water, Hit the side of the tank or sump, try to keep tank temp and room temp within 7 degrees f. of each other. any heating or cooling devices in the room need to be as spread out as possible, meaning: even temp through out the room. It is air out side the 7 degree window that will pull the moisture into the air. AKA "lake effect snows or rain" I've played with all of this and my cure was upgrading the temp control of the room. Btw when I vented in and out of aquarium stand I had lots of evaporation and phosphate issues.
