Easy Peasy. Gone in a couple of days.
 
I've had a lot of success spot cleaning with hydrogen peroxide. Turn off all the flow and use a long pipette to drop 3% peroxide on any areas with cyano. Peroxide is heavier than water and will naturally settle. Some cyano will die instantly and some will take a day. Leave the pumps off for 30 minutes.

Peroxide degrades into water but I still limited my self to about 30 ml per day of this in my 200 gallon system.
 
I would try a 3 day blackout period first and make sure you have measurable nitrates and phosphates. If your tank is only 3+ months old you are probably going through the ugly phase.
Thank you for this! My tank is over a year old not sure we’re the cyano came from but will give this a try thanks.
