This is my walstad tank, 3 months old.
all the fauna comes from the same natural pound (one adult fish, small 15 adult mollusks and several juveniles, and some worms. It has approximately 3.5 L of water and some plants; the substract is mostly volcanic rocks. I think it’s a stable environment, but my air bomb is very aggressive so I tried digging holes into the tube, but it’s really hard to regulate. I thought of leaving it in the surface like you can see in the video instead of in the bottom, but still it may be too aggressive, especially for the fish.
What do you guys think? Also, do I really need an air bomb here?

This seems very different from expected. Everyday it expects my temperature to rise a lot, but 37.3 Celcius... that would be fever temperature. I don't think its going to happen. So what? What is going on here?
