[ID] A macro algae? Don't see it in the pest guides

[alcimedes]

So there are two macros in the photo below. The one in blue I think it typical bryopsis which I'm working on removing. I'm trying to ID the one in red.

Anyone know what that is?

I have another angle, same thing. Blue is what I believe to be bryopsis, trying to ID the one in blue.

Blue looks like caulerpa. Not sure about the one in red.

 

[alcimedes]

Either way blue is one I want to get rid of, correct?

 

[alcimedes]

Someone said they thought the red one might be Caulerpa Prolifera, looks about right to me, and sounds like I can leave that one in the tank and it shouldn't blow it up.

Caulerpa of any stamp is a rooted algae, and unless your tank is over 100 gallons (enabling you to keep one of the only fish that eats it) it will destroy your tank. Scrub and dip the rock in hydrogen peroxide: rinse in discard water before returning it to your tank.

In the first picture the algae circled in red looks like Caulerpa brachypus or Caulerpa prolifera. The stuff circled in blue might be Caulerpa sertularioides or something similar. (taxifoila, mexicana etc) I can't really tell what's circled in blue in the second picture, but the one in red looks like Calurpa brachypus or Caulerpa prolifera as well. Whatever they may be though it's probably in your best interest to remove them from the tank altogether.

The red/blue circled items are the same plants, just different angles.

For the red circled plant, that's approx 1.5 months of growth. The blue circled one that's a week or so since I pulled it.

I don't mind plucking it off each week while doing water changes/siphoning, is it so pervasive as to justify nuking the rock to be rid of it?

Yes! By all means, get rid of it while you still can. In a year your tank will look like a freshwater planted aquarium.

lol, I love freshwater planted aquariums, I have 7 of them.

I also love my saltwater tank, so will start plucking this afternoon. Having spent 30 years doing freshwater, has anyone here tried the straight peroxide injection near the root base of this plant? Totally nukes most freshwater algae in seconds, but is safe enough for even the most delicate fish and inverts.
