Better Fresh Air Venting Plan

[neoh]

I had a problem with really high humidity in my sump area, as it's completely enclosed, and of course high humidity in the room - I wanted better CO2/O2 exchange through it due to pH fluctuation, so I added these fans to both sides:

The humidity on the inside and outside thing is a little tough, and probably non-existent because it's not one of those problems a majority of people have.

They do come with a heat sensor, and the fan spins faster or slower depending on the amount of heat either inside, or outside the sump area. I have one on all the time with the fan drawing air into the sump depending on the temperature inside, and I have another that draws air out depending on the temperature outside the sump.

Not sure if that helps!

Yeah, not many likely have the 'issue' that I do. I have 49.5 square feet of surface area, yes, feet... I am working to cover some of them with some form of acrylic to limit the evaporation somewhat.

But, say if it's raining outside, I don't want to be drawing in more humid air
