Yeah. Again only my opinion. But dinos comes back in 20 mins not a day. Cyano comes back in a day. And I believe dinos are in most tanks. They just don't always show to the naked eye. And trust me, dinos, atleast mine grow on everything! They almost always have air bubbles and stringy sticky streamers coming up into the water column. Usually topped with air bubbles. these are dinos. Yours looks and acts much more like cyano. But again just my opinion.
