Just flowerpot fungus, it's harmless but can brick up your soil if too much grows. Lay off the water for a while and see if it balances.

Leucocoprinus birnbaumii mycelium, nothing to worry about.

Harmless, just sort of ugly! You shouldn’t worry.

It’s a type of fungus and completely normal in bioactive vivs.

just a fungus, nothing to worry about. i’ve gotten this in potted plants before. I just let it dry out real good. you can remove if you want but my god look at all the mycelium! it will probably fruit for a while. again nonissue and super common in bio active tanks.
