Humidity Control?

[mark]

No water in my new tank, but I installed a bathroom fan in the fishroom in the basement. Just went to HD and picked up a dryer vent hood and punched a hole through the rim joist with a 4" hole saw.

If I can do most of my cooling (evap) with the sump, keep the humidity in the FR, the fan plus a de-humidifier I had already have, I'm hoping...


Rona also carries some low cost HVR units, looks like could be a weekend DIY.
