Dino ID needed

[Kaj Mählqvist]

I have been fighting dinos without any luck. Just bought a microscope but having a hard time deciding what it is.

Anyone able to help me ID them?

Check Taricha. A Guide to Dinoflagellate Identification in Reef Aquaria:

They look like large cell amphidinium to me based on the resolution (estimate of size) and prescence of beak.

Thank you! That definetly looks like the ones. The videos in the guide where great!

Time to start growing some diatoms then :)
