Microscope pics, but of what?

Dinos for sure. I had ostreopsis and eliminated them with a UV filter. I'm not convinced you have the same species.


This is Ostreopsis. Their movement is part of the equation. Ostreopsis move around a center point as if they are attached to a string swinging around. They also have a little notch at one end which reminds me of a mouth.

They free swim at night in the water column. Properly sized uv will eliminate them

Uv is your friend. They free swim at night in the water column.

Can you do a video of them? I'm not sure if those are really ostreopsis. Some species are not as susceptible to UV as ostreopsis is.
