Hey all.
Don’t know whether to leave it or not.
Depending on what type of algae it is I don’t want it to use trace elements.
It’s soft and springy.
Maybe a type of codium?

Cheers

Looks sponge to me. A photo under 12k or daylight would recieve a better ID

A photo under water would help. I'm thinking derbesia turf algae based on the texture, but I'm not sure.
