Dino type

Nice microscope work! Large cell amphidinium.
I forgot to ask you, I am going to remove the sand bed, but it sounds like there is there is not a lot else I can do except maintain parameters, keep lights low and increase diversity. I am putting in Microbacter 7 and have an order of pods and phyto coming in case pods eat dinos like some say they do. Do you think with no sand bed a UV and h2o2 would help?

I think that's a fine idea. UV is ok to run even if your specific type doesn't go in the water, because dino co-outbreaks are pretty common. If you have one kind, often another came in as well.

I also talked to Tampa Live Rock, which is not too far from here. I am going to drop by and get a little rock and sand from them in a week or so to seed the tanks for some more biodiversity.
 
They look like prorocentrum to my untrained eye. What is the main difference between the two ?
Sure. The front of the cell is the distinguishing feature. It can be difficult.

here's a look at the range of prorocentrum shapes for the feature at the front of the cell. (everything from o to v is recognizably prorocentrum. With O,R,T,U being kinds people post pics of repeatedly)

And here's a look at range of amphidinium front cell structures.

and here... (o through x. u-x look like most commonly posted large cell amphidinium)

The amphidinium always have a nose or beak that is separated from the rest by grooves. Prorocentrum doesn't have that.

So in the OP video, I'm looking at gooves like indicated with red arrow...

Small rock means small amount of diversity bacteria, dinos very likely to outcompete them quickly. Add it after you take care of the infestation.

It's so helpful to have smart people around! What do you do for a living?
 
@taricha wow, there is a lot more to it than I thought ! I’ll never assume what I see are prorocentrum just because they have a round shape…

Thanks ! :)
Mostly, the IDs are pretty well behaved but there are a few grey area cases. Mostly, I'm surprised how well our ID scheme works. Generally the ones that we can say are a certain type seem to act more or less the same.

I am hoping you can provide a little guidance. It has been a little over a month now. Although I knew it might not be of any help for this type of dino, I have run a UV and kept the lights very low. After about a week or two they seemed to be gone, but I kept going for two to three weeks just to be sure. I don't have fish in there right now, so there is no food going in and I added some live rock from the gulf to increase biological diversity. My sand is cleaner than it has ever been, but as soon as I begin to turn up the lights I see them starting up on the sand again. I'm not sure what to do at this point.

I’d leave your lights on personally and let the battle begin! I’ve been dealing with them for thr last couple weeks and I’m just about to win haha! I never turned my lights down for that reason alone! Every time I see vette guy recommended that I cringe! It’s always the same outcome I turned my whites back on and they’re back! My attack has been working great! Mix up the sunny x diy coral snow with some mb7… turn off your return pump and dose the tank and let it cycle for a hour with just wave makers on and continually turkey baste the rocks and sand to stir them up while running a uv light in your display. After a hour give everything one last Turkey baste, turn the return pump back on and let the skimmer and uv continue the work! I’ve been doing this daily and I’ve cleared about 80% of the sand dwelling ones. The key is to get them in the water column and use the coral snow to keep them suspended for a longer amount of time so the uv and skimmer can do their jobs better..
