Help with identification

[rhitee93]

I'm just starting to see traces of algae with bubbles that form over the course of the day. Fearing dynos again I put a scraping under my microscope. I couldn't get the thing to focus very well and the pics below are the best I was able to get this afternoon.

This is definitely not what I had before. Are the images good enough for anyone to ID?

Here is an FTS from a few days ago:

Not dinoflagellates, maybe diatoms.

Looks like diatoms to me as well.

Thanks folks, I appreciate the input.

Don't diatoms have little "Whiskers" sticking out the ends of the cylinder? It is hard to tell in my blurry photos, but I can see in the live view under the scope that these cells (?) don't have those.

There are several different types of diatoms. All these in that picture are diatoms. Some even look like pizza slices.
