Is this a Dino cell?

Secky · Dec 30, 2020

I’ve been trying to battle this ‘brown algae’ for quite a long time now. I’ve finally gotten a microscope to observe all the cells in my aquarium. Does the picture below look like Dino cells. The cells do move around and they go away at night and come back in the day. This makes me think it is Dino. Can anyone confirm? Thanks

Looks and sounds like it to me, but i am no expert. Might want to try posting it over here to get a proper ID.

Sadly, I believe those are large cell amphidinium. But hopefully I am wrong. @taricha can confirm. Tough, ugly buggers. UV won't help. You can read through this thread to choose your favorite approach, but expect them to persist for quite some time. On the bright side, they are not toxic so...
