Coralline Algae on SPS

[titustitus]

Hi, has anyone ever encountered coralline algae on their sps (base, tip or middle)? I currently am facing such a situation where the coralline algae is growing on the base of a birdnest. I'm not sure if it is spreading but I would like to know why this is happening, how it can be avoided and what should I do to help that birdnest now. Tried googling but not much returns :/

Here's a pic (sorry it's pretty bad as it's from my ipod):

Appreciate any help or advise

it grows typically on the dead parts of sps.

Cut them away. Probably coralline encrusted on it due to the part was oredi dead or about to die and bad flow too.

It happens in any tank, including mine.

thanks bros for the help! will go home and snip them away. but since it is the base, i guess i have to frag into few branches already

Usually harmless. Acropora prefer to grow over coralline. If you snip away the coralline and hair algae grows there then it's worse for the SPS.

Ya I agree with fuel, let nature take its course. But ultimately, you need to find out what causes the dead portion at the bottom of the bn. Like what yellowtang mention, high possibility it might be flow.

Cheers,
