Woof! What is the funkiest thing you’ve ever had tickle the olfactory senses!? Something that really curled your nose hairs?
For me it was just a bit ago. I am a few months in to my new tank, it started getting what I thought was cyano but after pondering and no3/po4 tests are bottomed out I’m thinking may be dino. Anyways, I put in some filter socks and microbubbled the tank and went after it with a scrub brush last night. After stuff cleared, about 10 pm or so I pulled the socks out and put them in a bowl of tap water. I think it is way easier to clean them if they haven’t dried out and I wanted to go to bed. I forgot about the bowl until about an hour ago, 4 pm... Smelled like week old dead snail mixed with skimmate and burned hair somehow. Pretty rough!
