Does it affect corals or fish?

Beautiful tank. Cyano can smother corals if allowed to grow over them and there is some evidence that it can adversely affect inverts.
You want to be sure to siphon as much up as you can before starting chemical treatments. Big question to answer is what about your tank conditions causes it to grow so large/fast? Real solution, of course, is to change these underlying conditions. Assume you're monitoring nitrate, phosphate, etc. and your readings will probably give you a good starting point as to next course of action.
BTW, I've never talked with anyone who didn't have problems with cyano at one time or another - welcome to the club!
Do you dose a carbon source?

Thanks for the response guys...and only carbon source is a carbon sponge...it's an AIO tank...macro aquatic 75 ml

I've been doing large chiclid fresh water tanks for over 10 yrs., But only had a salty for about 10 months
Looking at the picture it appears they that is where flow may be directly hitting the sand.
In myvtanks as the flow hits the glass, Esp the return, detritus builds up.
If you blow off the rocks or look while you feeds frozen foods you can kinda even see it happen.

I've read it's from too much nutrients in the water, I only feed my fish once a day and my corals twice a week....do weekly water changes of about 20 percent, and I've also cut back the light cycle., But still growing
Cyano feeds on a lot of stuff. If detritus builds up (and is decomposing) it can be feeding directly from both the nutrints provided provided from the decay and the co2 released by the bacteria decomposing the food source.
In a lot of cases of high nutrint fuels cyano you'll see spots of cyano in a lot of spots in the tank. Some spots worse than others.
Your tank like mine doesn't seem to have that.

Thanks salty appreciate the feedback
I had an outbreak a couple month back. I would suck it all off the rock and it'd keep coming back within a day or two. Well, I sucked it off one last time and cut my light schedule down to about 7 hours a day compared to 12, and it's completely gone now.
Cyano needs 3 things... nutrients (organic carbon source) light and slow enough flow to settle.
Restrict at least 2 of those and you'll be well rid.
Ramp up the flow a bit, this will keep the bacteria in the water column for longer. If you can, get a UV unit... that'll kill off the bacteria whilst it's in suspension.
Manually remove as much as you can and if possible spot treat any hard to reach areas with 6% h202 in a syringe.
If you're not running a skimmer then get one, that'll reduce the organics in your water dramatically.
If it's got really bad, go lights out for 3 days, cover the tank to stop even ambient light reaching it. If it's not too horrendous atm then reduce your lighting schedule by 50% for a week or so, with everything else you'll have it eradicated within that 7 days.
It will come back though... at some point. Unfortunately it's one of those things you have to manage... you may be rid of it for years but it'll always be there, waiting for the right conditions.
I'll post a couple of pics of my tank, before and after doing the above.

As you can see, there's still a bit hanging about but my whole tank (and I mean WHOLE tank) was covered in the stuff.

Wow....big difference...I will hit my LFS and pick up another power head ,and see what they have for uv. Already started cutting back the light cycle and reduced feeding....thanks for the advice. Will keep posted what happens... appreciate it tons
