Open Window Aquarium Smell

[piranhaman00]

Hello,

I can’t find an answer to this question. My aquarium is in my basement. I have all windows closed, tank has zero smell. I can stick my head in sump and cannot smell the aquarium water.

I wanted to increase pH so I crack a few windows, within an hour the basement has a fishy smell. The sump suddenly has odor, carbon or not.

I close the windows and overnight the smell is gone and sump no longer smells.

It’s the most bizarre thing, I’m wondering if increase in oxygen is causing bacterial blooms that create odor? I can’t see any water cloudiness.

Anyone else experience this? Windows open helps pH tremendously but I prefer the no odor with windows closed.

nose blindness, when you open the window it can change the smell.

Do other people confirm that there is no smell? Perhaps you've gone noseblind, and opening the window caused air movement which caused you to smell it for the first time even though it was always there.

Confirmed with other people because I thought I was crazy. No odor with windows closed.

You sure the smell isn't from outside or the basment?

Im starting to think it may be the outside air mixing with basement, although it is definetly a fishy smell , I also stick my head in the sump to observe this and it’s definetly coming from the water

I did not smell the musty odor from my HVAC until we recently opened the windows. The fresh air and reduced co2 made my nose more sensitive...

Interesting, but is that why the smell was then noticed because of reduced co2/ fresh air? Seems odd

more oxygenated air too. oxygen reacts with a whole bunch of stuff

Yes this is what I think is happening. I just didn’t know if anyone else experienced this.

I experience the same as OP but not every time. It's weird but I dont find the smell too terrible so I ignore it.

I experienced it too, when the tank was newer, but haven’t noticed it lately.
