Strange teal mold looking algae on sand?

[dankreef]

Hi slowly started getting some strange looking stuff on sand only. It's not looking like normal stuff it's kind of patchy and a teal color to it. Anyone know what it is ? Can I run something for it ?

Any help appreciated

What color is it when the whites are on? looks like cyano (which is red to dark red usually), by the way it is growing....

Id bet it could be cyano as well, different colors. And just a hunch, might be feeding off of big fish poop.

It's not red it's like a dark blue black almost. I'll try running some chemi clean

Consider stirring the sand if you haven't.

I sucked it out a bunch of times it kept coming back in force. Ran chemi clean for 2 days and it's back to crispy white . Thanks for comments. iPhone quick shot it's all clean though stuff works wonders.
