Fish room Ventilation options

[High Plains Reefer]

I am getting the floor done in the new fish room at the begining of the month so I'm going to get started on construction and I m trying to decide on ventilation options it will be in the basement total water volume will be about 1000 gallons I was thinking about a bathroom vent attached to a dehumidistat or should I go bigger?

Install a heat recovery ventilator. You will save on your energy costs as it takes the heat from the room and recovers it as it brings in outside air.

I am building my own. Ill be re-purposing a hood vent for a kitchen range and using it to push in fresh air directly to the sump. Im building a small box of sorts to go over the splash down point in the sump, with a 6inch fresh air line coming in and a 4" going out. The incoming air will also go through a CO2 scrubber to carbon filters before reaching the tank, to ensure its clean air.
Hoping to build it in a way to maximize gas exchange and also be able to vent most of the evaporation directly out of the house. I have a de-humidifier for the room just in case, but really striving to not use it, if I can
