Cyano?

[tuckdaway]

Is this Cyano or Red Corralline?

Nothing on sand bed just on rocks.

I have pretty good flow (Twin Tunze's) and only feed 1 cube Mysis 1x's/day....Nori a couple times a week for Yellow Tang/Flamingi Tang.

Thanks!:confused2:

Can you just rub it off, or does it scrape off? I have some dark red/purple coraline that is the same color as cyano, but is definitely not.

Type of coralline IMHO
Can you blow it off the rocks with a baster? If so - Cyano...

Cyano usually traps bubbles in it. Do you see any bubbles?

 

[jennm]

Coralline.

Not cyano.

Although it doesn't look like cyano, I think it might be... The first photo has a frag disk with a small frag on it and there looks to be a small bubble "under" the "cyano" if there is in fact a bubble there, I would say it's more likely than not cyano... Sorry...

well if it's soft its a bad algae.. if its hard its a good algae thats pretty simple

how long did it take to appear? cyno is quicker than coraline usually

I've had a number of cases of cyano...It's always easily rubbed off or blown off of rock and LS. Plus it'll cover glass and pretty much anything else it can grab onto.

I agree with everyone else and that looks like coralline to me.
