ID help? Dynos?

[Narideth]

Hi all, I was away on vacation for a few days and came back to see this black wispy stuff growing on the sandbed and some rockwork. I thought, maybe dynos, but descriptions of dynos say you can blow it away and suck it up, and two days ago when I got in there and gave it a good cleaning, it clung to the sand and rocks more like an algae? Clumped up and whatnot. I don't have any experience with dynos, and I hope it's not, but an ID would help me deal with whatever it is.

Corals all seem fine, even the ones it's growing around look unbothered.

Thanks in advance, let me know if anyone needs better pictures.

I've started a round of Chemiclean and lowered lights as I saw information elsewhere that pointed to this being cyano. Suppose we'll see, I'd still appreciate any assistance.

Without a microscpe there is no way to properly ID what that is. Why do chemiclean if you don't really know what it is? Chemiclean should be used as a last ditch effort to clean up cyano.

I can’t see the video so I can’t be much of help.. I would have waited on the chemiclean because Dino’s normally follow a treatment of that.. you’re killing off good and bad bacteria.. if what you have is Dinos it might explode now!

 

[Narideth]

This is why I asked. As I said before, other information indicated cyano and the conversation and reference photos went straight to chemiclean as the solution. I didn't jump to it randomly. How does one resolve an issue if they don't have a microscope to verify.

Got any pictures?

 

[Narideth]

Certainly. The tank lights aren't on yet, so nothing is awake, the light you're seeing is ambient in the room. I cleaned the sand 3 days ago, sucked and scooped what I could, it's clinging though.

Also, thank you! I know I sound grumpy, sorry about that.

Those stringy things def look like Dino’s.. cyano is more a thick mat “normally maroon” and will have some strings coming off of it.. I don’t see any cyano in your pictures.. it could be the beginning stage of cyano I’m not sure.. it’s not a big break out to say the least no matter what it is..

Does it go away over night when the lights are out? Cyano normally doesn’t.

 

[Narideth]

No, it doesn't go away over night. I've got some microbacter7 on the way, it'll arrive tomorrow, good to have on hand either way. I can do a cleaning too, whatever it is, getting it out is always a good step.

 

[Narideth]

Update: So, uh. It worked. The chemiclean completely wiped out whatever the black stringy stuff was, I've finished the water changes and the areas it was in look spankin' clean. I'm dosing Microbacter7 to help rebalance any bacterial loss. If there are any further results, I'll continue to update.
