Definitely looks like cyano, as others have said you will need to fix the underlaying issue causing the outbreak.
The fastest way of "getting rid of it" would be to siphon out as much as possible and use chemiclean. This will kill the cyano but can cause other issues like dinos if your nutrients bottom out. Also if the underlying nutrient or flow issue is not taken care of the cyano will return in a month or two. At least thats been my experience.
If you do go the chemiclean route you will need to add extra aeration to the tank.

@vetteguy53081 - I'm curious about the phrase nutrient imbalance. I've seen it used a lot in relation to cyano, but I'm not sure what it means. Are we talking nitrate and/or phosphate levels are simply too high, or that one is out of whack compared to the other?
The back story:
I've been fighting a cyano outbreak for a few weeks now. I'm not sure what all the causes are in my situation, but I believe the last straw was that I let me gyres impellers get dirty reducing the flow. That has been fixed, and the gyres get disassembled and cleaned monthly now. I've also bumped the flow through the return pump up a bit just for good measure.
I'm still pulling quite a bit of cyano out of the tank, but everything else seems pretty good. My nitrates are usually 10-20ppm and my phosphates are usually 0.15-0.2ppm. I've been slowly lowering phosphates since they are a bit higher than "generally recommended", but at this point I am guessing.

Yes nitrate and phos elevated but ive seen Cyano even with the numbers low. The biggest cause I see is lack of water flow, overfeeding and excess use of powdered coral foods

it produces too much oxygen
causes an imbalance of parameters
To much white light and lack of flow dead spots in the tank result in cyano outbreaks.
Thanks. I turned the white lights off today as an experiment. The flow should be good now. I'll keep vacuuming and run under blues for a while to see what happens.
In my experience cyano seems to come with rapid changes in nutrients. So a spike or a dip. I’m not sure if imbalance is the right word, but its another way to say nutrient instability. Since it doesn’t seem to matter whether it is too high or too low with cyano, we just say “imbalance”.

Chemiclean is not needed in this situation. Especially in a new tank it will only cause more problems Only necessary when nothing else works.
Agree 100%. Hold off on any chemical treatment methods until everything else has failed and you are losing your tank. It can often lead to much more difficult pests to manage and destroys your tank biome. Its almost like setting a reset button and you have to go back through the ugly stage again. That said, I do think chemiclean is one of a few drastic measures in a bottle that I think has its place. And if you’ve seen me around the forums at all, you know it is RARE for me to say about a chemical pest management product

Get some hermits if you don't have any, they will eat it. Using phyto and siphoning will not fix it instantly you'll need to keep doing it. Around .25ppm phosphate is not high and likely not the issue.
Yep. I can have a clean sandbed in the morning, and cyano will have formed by the afternoon.

Dude. I keep cleaning up the cyano and it keeps coming back!!! My LFS asked me to just cover it up with sand or get clean up crew that will roll over the cyano. I did all of this and it keeps coming back the very next day.
