Algae ID?

[Llarian]

I have a couple algae types I'd like to get an ID on if somebody can.

The first is a red bubble algae that's been spreading like valonia. It grows red initially in small clumps, but appears to turn whitish as it matures. It contains a gel-like substance inside, rather than watery like valonia.

It seems to be receding now that I fixed some water parameter issues, but its still pretty annoying and choked out a lot of my zoanthids.

The second is a plating algae. I can't tell if its calcerous <sp?> or not. Its not growing very quickly and is actually quite nice looking, but its taking up space on my rock where coral doesn't appear to be able to grow. I can break it off, but its encrusting under where the plates are, so its difficult to actually remove.

Thanks,
Dylan

The red bubble alage is "red grape algae" Botryoclaudia sp

The second looks like Mesophyllum sp or Erythrodermis sp. Not pics of the latter, so more than likely it is a Meso

I thought it might be Botryocladia at first, but there's no stem at all, its growing in clusters directly on the rock/glass and never up. The actual bubble certainly looks correct though.

You're definitely right on the Mesophyllum though, thanks. Gives me something to research.

OK, but there are a number of species of Botryoclaudia sp Some grow on "stalks, some grow in short clumps or clusters of just a few and some are solitary bubbles.

Go back to the link and you will see this on the second page

Ah, you're right. That's the one.

Thanks.

Now I just need to figure out how to get rid of it. =)
