Dino on GHA?

[Dweezilz]

So I'm not having issues as of now but I seem to have either 0 phosphate or less than 0.04. 13.5 Nitrate. Getting a Phosphorus ULR to be sure. I just started getting GHA in my 6m old 65g tank. Today in looking at the GHA under scope I see a couple suspicious round items that look similar to the rare dino Amphidinium. It's hard to tell. Maybe it isn't a dino but looks close. If it is, there aren't many cells as I've sampled dozens of spots in my 65g and this is the first few I've seen. Is this a Dino? If so is there any action to take if there are very few of them in the entire tank?

There is nothing abnormal about diatoms, dinoflagellates and cyanobacteria - the big three uglies - living in an aquarium. All three can be seen on hair algae filaments.

Most of those are diatoms, and like Dan says, those pics don't indicate a problem to my eye.

Yeah definitely mostly diatoms. Just that round thing moving that looks like a dino. I'll ignore it for now as you guys said, seems pretty normal.
