I am going to go with ostreopsis but will defer to the dino ID expert @taricha in case he spots another species also.

Assuming it is:
a) Hook up a UV the DISPLAY pronto. 1 watt per three gallons. 300GPH flow or whatever the minimum is to cool the bulb.
b) Amazon for Loudwolf Sodium Nitrate and find solution mixing & dosing instruction by googling it. Include in search string reef2reef or reefcentral
c) Amazon for trisodium phosphate (food grade is fine, but not the TSP substitute). Search same mixing/dosing instructions.
d) run your favorite carbon (GAC) and change weekly to knock down toxins.

Bad news is dinos suck. Good news (I think) is that ostreopsis are the easiest to knock back.

That looks like Ostreopsis. Those are toxic to invertebrates.

Just ostreopsis there.

Def Dino’s.. Peroxide dosing and gfo

No: GFO
Yes: GAC

The dinos are consuming all the phosphate and nitrate. The activated carbon is used to remove the toxins that some/most of the dino species produce.

So far just feeding heavy and not vacuuming the sand it’s seems like dinos aren’t getting worse more towards getting better
If this doesn’t work out then I will go a uv route

Hopefully you can solve without the UV expense, but I would be doing a bit of research now on UVs just so you can pull the trigger if things don't continue to improve. You want one rated at 1 watt per 3 gallons, installed to/from the display. To me, they are like fire extinguishers: everyone should have one around to use when stuff happens.

Avoid phyto and aminos at this point. Ostreopsis LOVE them.
