Algae identification

[scuba_steve]

Does anyone have any pictures that I can look at to determine what kind of algae I have

I know I have hair algae.

There is also a reddish-brown fuzzy looking algae. I am not sure what it is. It does not look like slime.

I also have a purple coloration starting to show up on my live rock. I'd like to think it is coralline algae, but I'm not sure. I am wondering if it might be cyanobacteria, but it does not look slimy.

On the sandbed, I have a bright greenish colored algae. Does not look like hair algae.

Can you see my situation.

Any help would be appreciated.

Here is a good place to start

And if you can post pics of your algae, it would be easier to help.

Hope you can make it out.

Beats me, but I have poor color perception. I'm gonna see if I can wrangle up some other opinions.

Can you take some closer pics? Can tell what the green stuffs are... probably something you want to pull off if you want the coralline algae to do well... :?

Doesn't look like anything permanent.
Is this in a fairly new tank?

Yes. Since the posting of the pix, a bright greent algae has spread over most of my live rock, pretty much wiping out the coralline algae.

Any suggestions?

I'll post some new pix when I get back my camera.

It looks like the same kind of green hair algae that I had when I fist setup my tank. My snails ate a little of it, but once I got my Yellow Tank ("Big Bird") he devourered it all up in two days.

As I understand it (And I an NOT an expert by any definition), the culprits are always Phosphate, Silicates, Lighting, and/or excess nutrients. And the solutions are almost always, remove the phosphates (use RO/DI water), make sure you are skimming, cut back on the light temporarily, and/or get some predators.
