29 Gallon Tank White stuff in filter

What is this white stuff growing on my filter’s edge? It doesn’t seem to be affecting the fish but its just pretty random. My 29g tank is still relatively new (5 weeks now). All readings are stable. And currently it’s still only stocked with few corydoras and danios

Looks like fungus to me. It feeds on dead & decaying bio gunk. It's harmless & is common in new set ups. Be careful not to overfeed.

Does it go away on its own??

As excess nutrients diminish, the fungus should retract. Be a good idea to manually remove as much unsightly fungus as possible.
