ID What I Call "Sea Ivy"

[Jenna09]

I am sure this is an easy ID, but I have been so busy at work these past months I have not had time to look it up.

It is growing rapidly in my tank and looks pretty but its getting out of control. Its growing around my corals, but doesn't seem to be bothering them. I have been "pruning" it but that seems to make it grow faster.

Here are so pics of some I pulled out this morning.

Thanks

Its called grape caulerpa, pretty sure people use it in their sumps, to eat up phosphates, its basically like chaeto.
It does grow very fast though, but i will tell you its better than the hair algae problem i have! :(
I suggest trying to keep your NO3 and phosphate levels extremely low, starve it to death essentially.

Caulerpa nummularia. Remove as much of it by hand as possible. You don't want it in your display because it spreads so fast.

Throw a Tang in there, he'll take care of that for ya.:mrgreen:

I will start removing it! Its already taken over lol

It looks pretty though so I will leave some and just maintain it.

I can't get a tang its a RSM 130D tank lol 34 gallons including sump!
