Black growth, ID Help

[ashtree68]

I came back from the holiday had an explosive amount of growth in my tank (could also just look a lot more since I was gone and not seeing it everyday) but was looking at one of the shrooms and it had black things growing up around it. Is it bad or harmful at all or just ugly looking? Thanks.

I know the picture is kinda bad, but all I could get with my camera.

It's some kind of algea.Try and blow it away.i've had that in the past,PITA to get rid of.

That's what I thought I thought it was some kind of hair algae but it didn't come up when I tried blowing it off may just not of had enough force with just a turkey blaster though.

looks like cyano, siphon it out during water changes,and if its bad siphon it through a filter sock and into the sump between water changes to save on saltwater. reduce nutrients as a permanent solution.

+1 for cyano...looks dark reddish to me in the pic above.
is that the only place you spotted it?....also, add more flow if you can!

May have to scrub it off with a toothbrush. Water changes while removing should help.

The only problem is it seems to have its base under the mushroom head I don't want to kill/detach the mushroom while getting rid of it or is it a decide which I'd rather have situation?

Take the rock out and scrub it away,mushroom won't die while you do this.

Darn, I didn't know all of that was bad I just thought it was another type or coraline algae or something like that, on another note I found a starfish on the other side of the rock that was kind of neat.

an asterina?
until they eat all your zoos or worse.


looks like cyano,
more flow, phosphate reactor, water change, many ways to get rid of it. needs to be stopped at the source imo, not just brushed off.

No, it looks like a legitimate starfish, I had asterina a while ago but they've been gone since I got my peppermint shrimp. This one doesn't look like them, it has five full arms, and is tan/red.

chemi-clean seems to work really well to kill cyano and then water changes and good skimming will keep it from coming back.
