Help identify the plankton.

[Andrey Grodno]

Help me identify it. I grow plankton, several species. But I don't know what kind it is.

a type of ciliate. Likely euplotes

 

[Andrey Grodno]

Yes, that's them! Thank you very much!

 

[Andrey Grodno]

Please help me with this one as well. What is it? I think they are dinoflagellates. But I'm not so sure about that.

yes. dinoflagellates. I see large cell amphidinium. There are some rounder cells, but because amphidinium has no hard shell, they can get squished and blobby from the microscope slide cover.
The shot from 0:07-0:15 you can see the flagella moving around the front part of the cell (epicone).

Thank you so much. Tell me, did you add silicate to the aquarium. How? I can't find a way to do it. Silicate glue is soluble in fresh water, but contains sodium. Silica rocks do not dissolve in water. So they say. So how do you add silica?

I've used these two.

Others have used other sources of sodium silicate / water glass solution.
