Are these hitchhikers?

[LeChef]

Excuse the dirty water I was scraping my glass but on my intake box there’s these white star looking shapes, anyone know what they are?

i also assume I’m answering my own question here but the little white specs that get attached to the side of the glass, that is sand correct? Or salt? It’s easily scrapable,

Here’s a pic: thanks for the help!
