Is this Dino?!?

My nitrates and phosphate are both zero! I pulled chemipure elite yesterday and over fed like crazy. How long before I see my nutrients come back out? This algae is blowing up my tank. The corals are starting to close up too. What do I do?

Looks more like diatoms to me but 0 nitrates and 0 phosphates could absolutely create an environment for dinos. I'd just try to get both levels up a little bit. Don't overfeed much, patience is key
