Seems like cyanobacteria.Hi thank you for the reply how do I take care of that? If you can suggest what might get rid of it.

It looks minor, if Cyano, it should come off easy with a syphon.
Review your nitrate trend as either 0 or north of 30ppm may trigger that. Keep both nutrients in trace amounts and neither rising or falling.
If it seems to settle in only small areas, sometimes the solution is to add flow so it can’t take hold.

Not sure there is anything you can do other than keep siphoning it out and wait.

Last thing I posted a week ago I have the Fluval smart reef tank lights I have since learned they aren’t the best but what I could at the time afford does anyone have experience with them as far as settings for best coral results?
