What is this? It's huge

[cactusmoe]

So I have had a tank for a while but due to wife,kids, school, work and everything else in life I got a "little" behind on maintenance. Anywho, I was cleaning it for the first time in a while and saw this pretty big looking thing. Anyone help me figure out what it is?

It's hard to tell anything (at least for me).
Can you try another picture more in focus?
And maybe adjust your white balance?

Possibly circle what it is? I can't find what your referring to.

Yeah better pictures for sure. Looks like bubble algae in the second pic on the left side. Unless it's all the same thing and that is what you are referring to....

 

[cactusmoe]

This is the best I can do right now. It is to the left of the snail. Almost dead center. There are some tube looking branches coming from it in some parts. You can see one or two of them in the background a little. The whole thing is a bluish green color

It's a rock...

Is it sponge,maybe????? Look up sponge and see if its it. Can't tell from the picture.

 

[Meanie]

Do you have corals in your tank or is it FOWLR? I would guess it's some type of algae but it's hard to tell from the pics....

 

[cactusmoe]

Better pictures. I thought it was bluish green but it looks now to be just green

Google "Ricordea Mushroom" or "Florida Ricordea"

Didnt see that last batch of pics before prior post. Check Grape Caulerpa and Valonia. Could also be some type of sponge.

Does it look like this?

I'd say grape or buble caulerpa, Caulerpa racemosa


Nevermind, I see AJ already suggested it.

 

[cactusmoe]

Ah. That is it. Thanks y'all!

 

[MARINECRITTERS]

I would remove it, caulerpa tends to be invasive.

Personally I'd through it in the sump refugium if you have one. Then just prune a handful on occasion if it grows too fast. It's a macro algae and will help keep phosphates in check.

It is definitely grape caulerpa and I'd be inclined to get rid of it. Caulerpa tends to suddenly die off releasing all sorts of nutrients into the water.

If pruned constantly, caulerpa can be a nice addition to a display. If left unchecked, it will easily take over your tank. Beware...it can go "sexual" and nuke your tank.
