Can anyone identify this type of Dino?

This Dino is covering my sand and rock. Dosing MB7, phyto and raising N&P for past week but doesn’t seem to be helping

Looks like prorocentrum to me. I recently had a problem with this. Took about 2 weeks to clear with multiple times daily manually disturbing - occasional siphoning, but mostly tooth brush and blowing off rock and sand bed, UV sterilizer 24/7 for 5 days, then just nights for 3 nights, and increased feeding by 50% to my tank. IDK if I got lucky... but that's what I did and I am looking pretty darn good now.

Thank you. What a mess…7 month old tank was doing awesome but N&P bottomed out and here I am.

I am also dealing with a bad case of Dino's. I installed a UV sterilizer, cleaning the rocks and sand daily, and replacing the socks in my sump daily after blowing off the rocks. I am also dosing Vibrant and Phyto.
