Coralline algae

[Chris-Dott]

I’m curious if this is green Coraline algae? It doesn’t come off easily.

Looks like typical “green algae” to me. Typical of new tanks with dry rock.

It has to be the same, the plug was completely white when it was put in. I don’t know exact numbers right now. This is my work tank and my test kit is at home. I would assume it’s good from my last test. Also my green mushroom has split. That was 1 big mushroom about 4 inches across when I left the office Friday. Now it is apparently 2 mushrooms about 2 inches across.

Wouldn’t it come off a lot easier if it was “typical green algae”

Definitely just green algae...tank is too new and that has spread and covered too quickly. Not all algae comes off easily unfortunately.

Part of the “ugly phase” that all new tanks go through

not 100% on rocks, 100% sure on frag plug, growth pattern, look behind sun coral, same
for me has been indicator of dropping alk balance w calcium.
blind guess your alk is low ,cal is stable ,not being used...

It is surface and slime algae and not even close to coralline which is calcareous. This is one where you can reduce white light and add cleaner snails such as:
Astrea
Turbo
cerith
nerite
Nassarius

6-8 caribbean blue leg hermits

And even a pencil urchin

Looks like you have some grreen there. I have some but its hard to get a pic.

To the OP. Its typical green algae.
I get the exact, you can see it in the pic, when I put dead rock in my sump. I just blow it off or take the rock out and use a toothbrush to remove it, rinse, then back in. In a few months it will be coverd.

I have some green that looks like yours in the pic. Hard green splotches come and go in my system.
