Default Ideal fan to vent a fishroom outside

I'm looking to buy a fan to wire to a humidistat. I'm not sure how often the thing will be operating but I don't want anything REALLY loud and I also want something reliable. My fishroom is maybe 50 sq ft.

Seems the options are a normal bathroom fan and the fancier inline ducting fans (Fantech etc). I'm not sure your average bathroom fan should run as often as this may require.

I'd also like to purchase this locally in Calgary. Thanks!

what's your humidity now?

I installed a bathroom fan for my fishroom but found humidity stays low enough I never run it.

Hey Brett A good bathroom fan will wok. However if your house is air tight then you are going to make sure that you have a line running in that is going to give you fresh air. you don't want a negative pressure from the fan.

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.

This is for the new tank. The tank and room behind it are essentially sealed off from the house. I am running a fresh air feed pipe into the room even though my condo is old and leaks like a sieve.

I don't really like the idea of the bathroom fan as you're garanteed to have some of that moist salty air escape the enclosure itself and find it's way into the ceiling above the room. At least the inline fans are mounted inside the room itself...

there must be a reason for the air to migrate past the fan but then it's easy enough the seal the fan enclosure to the ceiling,

You really only run into negative pressure problems with new houses and fans that surpass 300cfm, at that point an expensive air make unit is required. Brett you could easily modify a cheap hoodfan to serve what your looking for, broan ones go for around $30.
