Help to ID some tank growth

[patsheridan]

Hi. Two questions:

What might the reddish growth on the end of this piece of live rock be (aside from what looks like the beginnings of some bubble algae)?

And should I be worried about the dark growth in the middle of my lovely coralline algae?

Thanks in advance!

The stuff on your rock looks like red slime algae/cyanobacteria. How long has your tank been up and running?

Cyano bacteria.
Our good friend Todd and Michael wrote a nice story about it.

I have had it for about one year. Bought it up-and-running from someone else. First time I have seen this.

Now what!?!

Read the links @Diesel provided. Dosing with H2O2 can help

The first link is quite informative. The second link goes on for like 50 pages . . .

Looks like suction it out and maybe dose with Hydrogen Peroxide for a couple weeks?

@Diesel covered it.

The second one is long (I had a problem with cyano and sifted through/skimmed it, then contributed). It's more of a documentation thread of others who have tried dosing. It might be worth skimming because people document their results and if any tank residents seemed to react to the peroxide.

If the second thread is to long than you can always tag the person who started the thread in there for a one on one discussion.
A good thing about these threads is you can read the reviews from other hobbyist and how they tackled this problem in their tank.
It makes you more comfortable to do it yourself, if done wrong it can hit you hard.
I've done the thread myself as I introduced Cyano in one of my frag tanks till it covered most of the corals in there.
Started the treatment as recommended from @twilliard and by the two weeks most of it was gone, four weeks all was gone and didn't lost a frag.
You don't have a whole lot by sucking it out and testing for you No3 and Po4 to keep that in balance you might be good without the treatment.
Just see it as it is another tool in this hobby we can use to battle a problem we don't want.
Good luck my friend

Thank you my friend
Yes my thread is long this is why I had it locked to preserve the information within as people were finding it hard to go through the pages.
So I started other threads to break it down.

That is a bacteria with cells so small it is easily spread so caution should be in place.
I would start here
https://www.reef2reef.com/threads/positive-identification-of-cyanobacteria.253287/
If this comes out negative you have another family of cyanobacteria called spirulina
Both are easily spread but spirulina actually is a food source in the aquarium.

Sorry forgot to add to this.
If it is spirulina h2o2 has little effect on this bacteria

Thanks. I am changing over from my current 35g mixed reef to a 75g in a week or two. How might this tank move change the calculation? Everything in my current tank will move into the new tank.

Also . . . I'm assuming the attached pics are showing more of the same?
