Help, String Algae or Dinoflagellates??

I've attached some pictures of the algae i'm dealing with here, it's been going away however I've experienced some higher then normal nitrates for this new system which is what i figured was the cause for some algae sticking around but figured since it was receding it'll sort its self out. Local reefer told me it looks like Dino, which i agree it has some similar traits, but my Urchin is eating it or at least dragging it around, snails seems to be eating it and its growing on their shells and i haven't lost any snails, it also does not smell like anything whats so ever.
looking for some feedback so i can start dealing with it if i need to.

135G - 40G ESHOPPS Sump - 20G Refugium with Chaeto Approx 8-10w since cycle completed, after cycle wrapped up i went through a heavy diatom bloom which most of it looked like this algae, and like i said its being going away.

Salifert Tests

CAL - 470
DKH - 8.3
MG - 1350
Phosphate - 0
Nitrate - 10-15
salinity - 1.025

Appreciate the feedback.

I don’t think u will be able to get a exact id from those pictures but I do not think it is Dino. It’s a very young tank & u will go they different fases of all kinds of different algea. I wouldn’t do anything drastic for any type of algea I get in a young tank like yours. I wouldn’t worry unless it persists for months & months

Looks more like diatoms to me. Pretty normal for a new tank.
