Is this cyano?

[FishTrader]

I tried 2 rounds of Chemiclean as well as lights on for only 1hr per day for 3 days and this did not go away. Is it cyano?

Looks more like Dinos to me. Is it more red or more brown?

I am pretty sure that it is cyano. Does it easily blow off with a turkey baster?

 

[FishTrader]

Yes, but comes right back with a vengeance the next day

More red

Can you post a full tank shot? That is usually helpful.

Have you tried increasing the flow in that area? Looks like a combo of algae and cyano, or at least more than just cyano. Usually cyano is thick mats, which is why I said dinos since in that photo it looks more “whispy”

I just blew this rock off. I'm doing a water change in a few.

I've added a mp40qd right before the chemiclean treatment. Now I have that and a gyre 330 for 65g Peninsula

This is nuts! An hour after I blow off the rocks the cyano grows again!

Going to do a blackout again.
