I have been fighting this for a few months. The stuff in the sand seems to clump and is very hard to vacuum because it is as heavy as the sand. I have used Red slime remover, with not much help. My nutrients are Nitrates 12 Phosphates .06 Salinity 35 Alkalinity 9.6. I am dosing Red Sea four part and have been happy with tank for years. Coral do not seem to be affected much. Tangs do not seem to eat it. My clean up crew do not seem to live very long. My sand sifting starfish looked like something was biting it. Can someone help me please?
Dynos or Cyano?

Just to be sure: It's not a digital one is it? It's a classical compound microscope like you may have had in school, right?
I'm asking because digital microscopes often don't have the required magnification or resolution capabilities.
You won't regret the purchase, microscopy in combination with a reef tank is pretty fun: https://www.reef2reef.com/threads/microscopy-thread.1138845/

There should be a 20x and a 40x objective together with 10x eye piece. These will probably work best for the identification. It doesn't matter much that it's cheap, it will probably do just fine
Tag me once you have some images, I'm curious what you will find! You are also welcome to post your findings in my microscopy thread if you want.
Side note:
2000x is just marketing.
You won't be able to go much further than 1000x with light microscopy. Yes, if you have a 100x objective and a 20x eye piece you theoretically should end up with 2000x, but the image will be too dark to be useful and the resolution won't increase beyond 1000x making it like a "digital zoom" which doesn't provide more information. The wavelength of visible light simply won't allow for higher resolution.

I posted my experience in the thread above where I outline my experience dealing with this kind of green toxic growth on the sand bed for the last six weeks. I am on day 3 of removing the patches of sand with green growth and top dressing with ocean live sand from Tampa Saltwater. So far the sand looks immaculate with no signs of the green algae. Notably, during the first there were small patches of sand in remote areas of the reef scape. I mixed those areas up so they came into more contact with the TBS sand. It is day 3 now and no sign of algae regrowth. The sand is basically complex clear!

Thank you for all your information. I didn't get a microscope with imaging. I will share the information, if I can match what I see to a known strand or algae.There should be a 20x and a 40x objective together with 10x eye piece.

I will keep an eye out for how your's is going. I guess you have taken away the light and provided beneficial bacteria to the system. Sounds like a good idea. Do I have the general Idea of what you are doing?

And detritus... Weird color for Ostreopsis though. Usually they are brown but without the microscope it looks green. Have you tried getting a single sand grain under the scope?

I'm sure AI is wrong in this case. It's Ostreopsis. It has a pointy end and not a "beak" or "nose" like Amphidinium has. It also tries to move in circles around a point in the distance which the tip points towards, but in your video the cells struggle to do this as they crash into each other
