Help with what something is

[firemedic]

what is this and how do I get rid of it?

If thats algae I strongly recommend a urchin or a sea hare. If you get a sea hare take it back to the lfs because it will starve and it releases toxins when dead or strwssed

Looks like algae
Water changes and add a uv sterilizer depending on tank size
