Help ID this nuisance calcified algae - how to rid my tank of it?

[patriot dude]

I've had this strange calcium like macro algae recently return, it was nearly gone and I can't say what changed to allow it return in force. The only change I can recall is that I did a decent water change and it seems significantly worse since then. I rarely do any water change. What eats this stuff? My phosphates and nitrates are zero and I only feed one cube daily of Hikari spirulina brine shrimp or Mega-Marine Algae, nothing else, no other added nutrients. I dose only B-Ionic #1 and #2 and Red Sea NO3Po4X and have not changed either recently. I grow plenty of macro algae in my refugium and run a Tunze 9415 Skimmer on my CADE 1500

Does anything eat this stuff? Can anyone recommend how I can better control it naturally?

Need clear pics under white light

Hopefully this is helpful. My iphone is very old and doesn't process blue light well.

Yes, looks like green cualerpa algae but if you are specifically talking about some of the white calcium on the branches then I wonder about your iron levels along with your bottomed out nutrients allowing some type of algae to attack the macro.

That would be amazing and good, I'm concerned it is something worse like this.....

You could be right. Strong resemblance in the first link to finger algae.

That does look like neomeris, I had some come in with a macroalgae order but it wouldn't grow in my system.
