Excess moisture in fish room

Can't you just cut a hole in the roof? That's what most people do

Lol!

When I build mine put in a small bathroom fan over the sump. Was also going to put in a dehumidistat so would only run when required but never got to it (moisture not a problem).

my fish room is totally insulated from the rest of the house.Drilled 2 holes opposite sides of the wall going directly outside.One draws fresh air and the other draws out the humid air, both fans are running of a dehumidistat for that room.

As far as bathroom fans go, the squirrel cage fans are very quiet

HRV (heat recovery ventilator). Sucks air out and preheats the fresh air coming in through a heat exchanger. No negative pressure situations which can be potentially dangerous in homes with gas fired appliances such as furnaces, hot water tank and fireplaces.
exhaust fans sucking air out of the room and pulling fresh air in is a similar setup, you just don't get the advantage of preheating that air, so in certain area's/circumstances, supplemental heating may be required.
