Please help me ID this plant

I am brand new to the hobby and need help identifying this plant.... It is growing out of my live rock in a couple of places... Not sure if its good or bad.. And yes i know I have bubble algae.. Currently working on the problem.. I am manually removing it from the rocks.. I just wanted to know if I should let the plant grow or remove it with the algae
 
Caulerpa racemosa (Grape Caulerpa). I would remove it as it can grow out of control. If you decide to remove make sure you try to get the roots as it will typically grow back if you don't. If you have a refugium you can put it in your fuge as it is a great for nutrient export, just make sure you read up on keeping Caulerpa in a fuge. Here is a great link for plant ID as well as critter IDs. Click on the pics to get more info about the plant/critter.
