Help with this

Is this cyanobacteria? It collects on the glass and rocks every few days, It is easily blown off the rocks or scraped off the glass, I have had some cyano lately and been doing lots of water changes.

No. It looks a lot more like flatworms to me, but a close up would help.

That's flatworms!

When I first looked at the picture I thought you had just fed flake food :P My eyes immediately went searching for Cyano on the rocks so I didn't even focus on the flatworms.

Definately flatworms tho. I've had luck with a product by Salifert called Flatworm exit, but it can be tough on a reef tank (your corals might take a down turn for a week or two, but should bounce back after running some carbon and a few water changes).

I would suggest siphoning out as many as possible. IME/IMO, FEE should be used as a last resort, not a first line of attack. You could also try a wrasse. I have a pair of blue star leopard wrasses the wiped my tank clean of flatworms in no time at all

Wrasse . Yep that is what I did. Awesome fish to have for sure
