Dinoflagellates, ID; Amphidinium

[Atomins]

Hey everyone, battling dinos right now, bought a microscope to get some better and larger images, i figured these images/videos could maybe be useful for people trying to ID, this is Amphidinium, not sure if large or small cell but someone else can try to confirm. i did a 3 day blackout to no avail. I fixed my nutrients and now am dosing silicates to try to promote a diatom bloom. anything that is not the common path to get rid of these guys would be greatly appreciated, they are so ugly!

Doesn’t look like amphidinium. Google amphidinium images for a comparison.

I thought amphidimium because it does not go into the water column at night, but I could be wrong! I will double check, what do you think it is?

I have seen these in my system and thought they were some type of dinoflagellate but I did not pursue identification.

Did you get rid of them? If so how?

Here’s a current pic of tank, lost some coral due to this “organism” smothering some of it which led me to Dinos. Gets very stringy and came back after a 3 day blackout

so after some more digging it appears as prorcentrium dinos, here is my reference photo and a pic i took on the microscope. appear as same shape and roughly same color, but they do NOT leave the sand at night.
