Dinos making a return?

[Sploot]

Hello all,

Managed to beat prorocentrum dinos a few weeks ago. Recently I've noticed this in my tank. Wanted to get some opinions of whether I'm dealing with another strain of dinos now or it's an algae. Did lose some trochus and turbo snails which makes me think it might be dinos. However they do seem to present when the lights are out as well.

Thanks in advance

It's a little hard to see, but to me it just looks like some type of filamentous algae.
Does it blow off the rocks if you blast with a turkey baster or is it firmly attached?

It blows off the rocks very easily for the most part.
