Phytoplankton contamination?

[TangsRLife]

So I’ve recently been culturing nanochloropsis for a month now and they’ve started since the beginning and was just wondering if this is a type of contamination and if it’s possible to save my culture? It looks like a bunch of dots but my tubing isn’t centered because I don’t have hard tubing so could it be dead phytoplankton building up?

I can't tell Ya but here's a bump.
