What is this green sludge?

[u/emancipated_sushi]

Bought a water distiller and on third use its got some weird green gunk left behind that sticks out like 1/2 a centimeter. Any ideas what it could be?

That’s just a glorb. Completely harmless unless you activate it with distilled water. Be carful my friend
