Cyano should be expected in a new tank like yours...Totally normal... And always the last of the new tank ugly stages
Siphon it out during a water change then shut lights off for 3 days...Then do another water change and siphon whatever is left....repeat every couple weeks till its gone/passed..

Yeah, that's nothing to be concerned about.
Siphon it out every few days with a couple of gallons of water.

If its "live sand" then Id suggest you wait and actually return it for dry sand or thoroughly rinse and dry it to remove as much of the dead organics as you can...
Then add it whenever..
Even dry sand should be rinsed very well to remove small fine particles that WILL cloud the water and get on everything..

So what have you done to try to help it?
Siphoning it out?
Turn lights off?
Chemical treatments?
Water changes?
Nothing?

Try some Chemi-Clean. We used it on our 90 gallon display at work that was full of corals. Never had any issues with livestock being affected and it took care of the cyano issue quickly.

Cyanobacteria is almost always one of a few things (or a combination of them).
1. New tank uglies
2. low flow
3. excess nutrients
4. exposure to sunlight (I find this especially a problem in the fall/winter)

Wait out the uglies.
Increase flow by adding one or more power heads to help randomize the flow.
Remove the source of excess nutrients - either by decreasing the feeding, water changes, or allowing the rocks to fully mature (they may be leeching PO4)
Block the sun from hitting the tank, especially if near a window.

Manual removal isn't usually too hard. Siphon out as much as possible during your regular weekly water changes. If that just isn't working, then Chemiclean will work wonders, but it will only fix the symptom, not the problem.

Thank you.

Could be point 1 or 2 I guess.
the tank is about 20g and I've one Tunze 6040 In it.

Because it likely contains a lot of dead organic material which will potentially make your problem worse... I would rather start with clean dry sand vs adding all of those extra organics to a problem tank..

When you are starting a tank using live sand without rinsing it can be just fine...

My personal preference is to never use live sand and I suggest you rinse it for your situation... Thats my opinion though... Ive used live sand in the past and have had more problems with cyano, etc...than when I used dry/rinsed sand.

That might've been the wrong video. They have a few of them on live sand...I was trying to answer the why do they sell live sand part of your question.

In one of the videos Ryan explains that one type of live sand is covered in live bacteria while other types are seeded with dormant bacteria that become live once the right conditions are met.

Personally I have used live sand in all of my saltwater aquariums to date and I did not wash any of it beforehand. This made the water cloudy for days. If I had to do it over again, I would definitely wash it to remove all the fine particles before adding it to an aquarium and then add a bottle of live bacteria afterwards to get things going.

My personal opinion is that it is a gimmick to get more money out of people. Even knowing this I still buy it because I like the particular look of the Ocean's Direct sand.
