is this cyanobacteria?
it's taking over the top of the substrate and going up the walls and starting to cover some of the liverock and the decorations (we have some fake anemones in there)

there aren't any fish in the tank, just a turbo snail.

What should i do?
 
no i dont have a camera.

It creates a film, if that makes a difference, so that it spreads across the tentacles of the fake anemones. and there are air bubbles between it and the liverock underneath.
 
mine looks more like cyanobacteria. it's more red and somewhat less stringy than the pictures im seeing of the dinoflagellates.

My tank finished cycling a few weeks ago, we got a dwarf lion but we could not get him to eat. We were told to ignore it and he was probably just not eating in front of us. so he died last week. while he was in the tank, there was some of this stuff, but there's probably 3 times as much now.

we use RO water with "instant ocean" salt. We were putting live brine shrimp in everyday for the lionfish, but not anymore. we add buffer plus and purple up as recommended on the bottles.
 
Sounds like cyano to me, rather than Dino's....What flow do you have in the tank?

I wouls stop adding the buffer unless you have found a defficiency on your water test results that show that you need to be adding it...And i would stop adding the purple up....really is not needed...
 
I would say cyano as well. Especially since you claim you can see air bubbles on it.
 
I agree with Niko on stopping both of what you are adding. Especially the purple up as it doesn't contain the correct calicum. Time and good husbandry will give you coraline.

As Niko asked flow is important, and so is possible overfeeding (which if the lion wasn't eating what you were feeding is a possiblity)
