Algae??

Does anyone know what algae this is? It’s covering my top half of my rock. I’m thinking diatoms but not sure.

still hard for to tell for sure. Sorry for my old eyes. I can't tell if the coloration is due to the lights, or it may be cyano.

Its chrysophytes and is a slimy, fuzzy algae that is photosynthetic that loves light. To remove it, it is best to remove the rock first and clean the algae outside of the tank in a container of tank water by scrubbing with a firm toothbrush or automotive detail brush.
After cleaning, return rock to the tank and add cleaners such as : Chiton snails, Pitho crabs, ninja star snails and Caribbean blue leg hermits.
Reduce white light intensity and is tank at or near a window?
