Welcome to dinoflagelates......I assume the tank is fairly new?

cyanobacteria

Check your Di stage on the rodi. Add some gfo in a higher flow area(not too fast as you don't want to strip nutrients too fast. ) thats for diatoms.
If its dinos you may want to look around here. some are having issues with super low nutrients and the appearance of dinos.

I am not a expert but I see dead snails and thats usually a pretty good sign of dinoflagellates. But the best way is to look under a microscope to identify them first.

Looks like dinos to me... have heard that their appearance in an established tank can sometimes be caused by imbalance of nutrients, even if they're very low... usually no3/po4 ratio.

Try turning your lights off for 2-3 days and manually removing as much as possible without doing a water change. Take out all mechanical filtration and clean as best as possible after day 3. Dino's can be a pain, but can be beat. From just a few days of lights out to having to use products like dinox by fauna marine.
