Possible Dinos?

[tmb22]

Dino's can swim whereas other algae that might be similar-looking in bloom form cannot.

So if you swirl up a sample of mat to break it up, only dino's will re-coagulate into a mat or strands after a little while. (Being under light should help.)

There is a test that involves a paper towel, but I dunno if that's for diatoms or dino's.....not sure it's required.

Interesting. Seems like a pretty straightforward test. I'll have to give that a try too just to put the nail in the coffin. Although I'd say it really already is completely identified thanks to you guys. Thanks again
