Ideal fan to vent a fishroom outside

[rayjay]

Before I bought and installed my HRV, I used Princess Auto fans.
I started with one, but realized that I was pushing out CO2 laden air, but drawing air that wasn't much better from the house as a whole to replace it.
I turned it around so I was pushing fresh air into the room instead of out of the room. I ended up trying two fans but it still wasn't enough due to the approx. 1000g of water I had in total so I installed an HRV.
Unfortunately it wasn't in time to save the doors and windows and a lot of drywall in many rooms so it was a costly delay in fixing the humidity problem.
