How big before humidty problems?
 

I am in the planning stages of a new tank and finally have the wife on board. I want to keep her on board. There will be no fishroom and that means no dedicated ventilation. I realize evap is directly related to surface area and to a degree lights used.

I am hoping for a 6'x24"x24'h tank
or even better would be a 6'x30"x24"h
OR EVEN Better 8'x30"x24"h but that is probably not in the cards.

am I going to have humidity problems from this tank? what do people who have large tanks do about humidity when they aren't able to directly exhaust outside?

I was planning on T5 MH combo. I don't know enough about LED to be confident in what I'm buying.

Thanks in advance!!

dehumidifier...

better yet would be to have a window in set room that is always open.

I have a de-humidifier to keep my house at 50% relative humidity. Without it my humidity would be over 70% and the windows would be soaked and mold would grow.

However I live on the coast you are in Calgary you might be OK. I would see how it goes before purchasing a unit.

The best, though not the cheapest option is a HRV & a/c for the summer. I know someone that had a fish business out of his basement, over 2000gal of tanks and his house was like going into a rainforest until he went with both... never had a problem afterwards..

My house has hrv, and I'm planning an air conditioner this summer. I'm hoping that I won't have any problems. Leaving a window open full time is not an option. It was -40 with wind this morning lol.

In my fish room, I'm lucky enough to have a window that I can keep open. But in this cold, I had to shut it. Even with my dehumidifier running all of the windows on the main floor have steamed up and I also have ice on the window in the fish room.

I think that an HRV is the best for sure. If you already have one I'd think you'll be just fine.

what year is your house ?


new houses that are all sealed up like a freezer bag will retain more humidity....



I had an old bungalow from the 50s and you could feel cold air coming in the electrical outlets...

2016. Well looks like I'm going to find out.

Calgary is sooooo dry you likely will not have any problems with humidity. I would suggest to turn on your recirc fan for your furnace and just leave it run 24/7 if you dont already have it running all the time. That will move all the air in the house around. Also leave your blinds up a bit.

Having an HRV will help a lot.

If you have a heat pump some of them have dehumidifier mode.

If your going to run the furnace in circulation mode I would make sure it's at the lowest speed.

If your looking at installing an AC unit I'd recommend a ductless heat pump one. They will heat/cool and dehumidify.
