How do you control humidity?

You mean the windows are not supposed to be wet inside all the time
JK I am having sweaty window issues also, I am almost certain it has nothing to do with the 350 gallons of salt water and the 4 gallons a day evaporation, I am blaming it on the toilets as the tanks sweat when you flush I am thinking HRV is the way to go, especially as the furnace is located in the same room as the tank.

Yes Keri, I have done them all myself. But perhaps not the way the pro,s install them, making mods to suit my own needs. The hardest part is running the ducts if the basement is all finished. If not then its not to bad.

I ran my return fresh air different than specs say, depending on the amount the places were finished. My home in Thompson had a nice crawl space, so it was fairly easy.

I use a Venmar 3100 Air Exchanger/Dehumidifier.
This unit does it all. It sucks in dirty, stinky, humid air from the tank room, takes in fresh air from outside, runs it all through a HEPA filter and heat exchanger, then blows the fresh, dehumidified air into the furnace ducts and expels the bad air outside and drains the water down the drain. Runs about 15 watts on the power cycle I use. Highly recommended!!

I do have to top off more though because it drys out the air in the room.

I simply had an ultra-quiet Panasonic bathroom fan installed installed over tank as part of the basement reno. It's hooked up to a plain old programmable timer. Works just fine.

That sounds pretty sweet!

In my basement I have well over 1000 gal. of water. I run an exhaust fan during the day (14 hrs) and dehumidifier at night (10 hrs.) in the winter and the fan on all the time/no dehumidifier in the summer. This keeps my humidity in the 40-50% range, which isn't too bad where I live.

I installed a inline exaust fan in my attic with two ports in the fish room still waiting on a dehumidistat? Nice thing about them is you can't hear them at all.But 12hr in my attic really sucked. First I use a regular bath fan and it was good for about 2 years then the port locked close and the line filled with water and what a pain. All fixed now just remember the lesson learnt, check outside ports and inside for obstruction. I now have the humidity reading also, I could have wrecked my roof if I hadn't have caught it.
