[nuggets423]

I have some green and brown like algae growning all over the live rock and crushed coral. Is there somw way to get rid of this or is it ok to have in the tank?

How long has the tank been setup?
It's normal for new tanks to go threw a cycle, and develop this algae. A couple of things to help reduce it, are increased water flow, cut back the hours of lighting, and control the water quality.
