Just wondering what this is, if it is a type of coral or is it a type of algae growth. Please help. Thanks.

That isn't cyano. Cyano is burgundy, red, and kind of rusty looking. What you have looks like a species of sponge. To get it out, take some tweezers and pull it off and throw it out. Most sponges don't impact your tank except sometimes making an eyesore. It actually is a sign of good water quality, however it can spread and overtake corals.
