I have moisture problems in the basement that aren't being solved by a dehumidifier. The problem is compounded by the couple aquariums I have down there.

I'd like to pump out the stale humid air out of the basement, and pump fresh air into the rest of the house.

My concern is humidity. The summers here are pretty humid. I don't want to be pumping more humidity into the house. Will either an ERV or an HRV dehumidify the incoming air?

I had my local guy here yesterday woking on a quote to replace my old leaky a/c with a heat pump. He suggested an ERV but was a little shaky on what would happen with the humidity if I"m pumping cool humid air out of the basement, and feeding the ERV with warm humid air from outside.
