I used to have a dino outbreak about 2 months ago. it was horrible these little reddish-brown strings with bubbles were everywhere! it sucked and my water quality was great and i had a fuge and i didn't overfeed. Dino's can be a PITA!! but I was able to finally resolve mine by increasing my pH to about 8.4-8.5 and they went away.
they can come even with perfect water conditions and don't need light to grow. turning your lights off for a little will help but only temporary. they will still be there when the lights come back on. Nothing really eats dino so the best thing I found was to increase pH.
and cyano usualy has a more mat like appearance and is usually red and dino's are long and stringy and grow on anything including rocks, macro, sand and corals.
