Do those units have an exchanger core? How do they warm the incoming air?

I'll chime in a bit here since I've been looking into this closely as I plan my 360 installation.

The humidex basically a combination of a vent fan and a humidistat that turns the fan on/off based on humidity. It vents out of the house only, and depends on "leaks" in the house to bring new air in. That would be a concern in a very new, tight house due to negative pressure.

A good vent fan to the exterior attached to a humidistat would do about the same thing. I would guess it would cost less, but require a bit of DIY.

Finally, the last thing I'll mention is that it would be good to control the space where the humidity accumulates. If you can get good containment of the tank and fish room, you have a smaller air volume to deal with.

I was just going to run the bathroom fan 24/7. This winter is crazy warm, so I am not too concerned about the cold air coming in. Next winter might be different.

How effective are de-humidifiers?

For de-humidifiers take a look at sears.com for an idea. They're rated in pints/day and come in differents sizes (up to 70).

Thanks mark, will do.

my dehumidifier works OK. not the greatest. we're having a HRV installed sometime in the near future to deal with the mugginess of the house. the humidity heightens the smell of the pets, it's unbearable some days.

Would an HRV be very portable between houses do you think?

For my 375 I started out with a bathroom fan in the fish room, and found that it was noisier than I liked given its capacity, and salt creep became a problem.

Eventually went with a Vortex inline squirrel cage fan like the attached.

Much quieter (also due to being placed remotely in the finished basement ceiling) and more powerful. Vented out the wall, with a fresh air supply provided to avoid any negative pressure situations.

I got mine from the local hydroponics store ... they even accepted a charge card

My house is old, and crappy windows, so there are lots of air leaks in.

I bought a bathroom fan and a control to turn the fan on when it reached a certain tempature in the fish room. My plan was a hole out for the fan and a hole in for fresh air. As far as heat I thought the cold air being drawn in the room from the in in hole would keep the temp. down in the fish room.

Then I read more and did the HRV route.

Caution note.

Before anybody goes punching holes in their houses I thought I would let you know that there is a "minimum distance" to things like air inlets vrs. outlets. You would need to refer to local building control regulations for the exact distances. For example; you don't want a furnace fresh air intake too close to an exhaust outlet. It's like smoking cigerattes
