Are you sure its Cyano?
You can do some things such as cut back on feeding, pull out any dead stuff if you see it in there like snails, cut back on lighting, increase your flow. Also if you manually remove cyano from your tank I would use a baster and turn off your pumps and try like heck not to move the cyano around too much so it doesnt spread too much.
All else fails and if you get beyond your limit with patience, there is a midication you can use. I would try the above first before you go that route.
