Is this cyano?

[Wolters_88]

I think this is cyano but really don’t know. There is red/brown stuff all over that was not there yesterday.

It’s in my RFG too.

Does look like cyano.

Is it on the sand bed and in low flow areas? Cyano will usually start on the sand bed and low flow areas first.

Nope, not in the sand bed. Just several spots all about the size of a dime on this one rock.

Is it stringy or do you see air bubbles? Looks stringy in the last photo. Cyano. Just get Chemiclean. Works like a charm but your skimmer will go completely haywire.

Does it blow off easily, if so then it could be cyano.

It looks a bit like dinoflagellates, what’s your current parameters

I would not, i would just take the top off and let it work without the lid.

No, I tried blowing the crap off for a solid ten minutes and only push the sand below around.
