Green Bubble algae

[Lesely]

hi, last night I decided to get on a ladder and look inside my overflow. (not a pleasant experience) lol
I nearly died, I have green bubble algae. There is 2 clumps about the size of a fist growing happily.
I don't have any sign of it anywhere else DT or Sump ?
Is it a concern ? Should I remove it ?
And last question is why does it grow in the overflow box only and not anywhere else. ???
I actually still have some GHA in there as well, but that has been there for a long time and its never spread anywhere else so I have just left it alone.
Is bubble algae a sign of excess nutrients like most other algae ?
Any advice would be greatly appreciated.
thanks

If it was growing in my non-existent overflow, I would leave it so long as it wasn't blocking flow. It obviously is just a good place to grow so it's basically acting as an algae scrubber.

Yea, just make sure it's not blocking flow and you have an unintended turf scrubber.

Idk but consider yourself lucky! Just check your filter socks and pull out anything that runs through.

If it's in the overflow, guess what? It's already in the display.The reason it's only growing in those places is that that's where the nutrients are and the predators aren't. ;)
