I thought the same thing!
Long blackout against dinos and GHA.

Likely why it does not react to treatment.
I’d just chemi-clean that regardless of what it is as this treatment is fast and efficient.
Reefs by Steele is running an experiment using rotifers to eliminate dinos. OP search his threads
scratch that it is to eliminate cyano NOT dinos

I fought diatoms & GHA for around 6 months before I found the fix for my system. At times the diatoms would bloom so heavy the sand would actually turn black and I could grab it out of the tank with my hands, it looked like a bed of sea weed strips. The GHA covered every inch of my rock work and my corals. Blackouts didn't work, and I was removing the algae by hand every day.
This is what my LFS told me to do, it worked for me & my 30 gallon:
Immediately cut blue light spectrum intensity down by 50%.
Turn any white light down to 0-10% intensity.
Turn any red/green light down to 0%.
Large CUC.
Small doses of phyto plankton twice a week.
Water changes & filter changes every 2 weeks, religiously.
After doing this the diatoms and the GHA died off within 2-3 days, then I started raising the light intensity gradually. I started at 50% intensity & raised it to 85% over a span of 12 days. I learned that anything over 85% intensity blooms GHA and diatoms like crazy in my tank. Initially when I had the issues my white light intensity was around 35-40% & my blue spectrums were at 110-115% intensity, which made a par of 85-130 throughout (softies only tank.) The lower settings I have now of 85% blue spectrum & 5% white surely lowered the par a bit, but the corals are doing better than ever with the GHA & diatoms out of the tank, despite the lower light intensity.
Don't know if it'll help you, but it's what got me through. I truly believe the cause of my issues was the excess amount of white light & the high light intensity in general.

Ended up doing it. I have taken out all corals, and turn off the lights. Hopefully this work.
Tomorrow I'll start removing a bit of sand each day, as I have decided to go bare bottom with the tank. There is just a very thin layer of sand, so it shouldn't be a problem.

Are your fish still in there?

It worked.
I ended doing just a 7 days blackout. Almost all the GHA died, and no sign of Dinos anymore. I suspect whatever was causing them was in the sand that I removed, because I moved the rocks that were glued to the corals, and whatever dinos they had in them dissapeared after a few days.
As I have no sand anymore I'm letting my Xenia and the GSP run wild, as they grow super fast, and I don't want to keep fighting them so they don't spread to the rest of the tank. The aggresive corals and anemones should be able to fend them off, and I'll sell whatever isn't capable of surviving against them.
