Its hard to tell....but is that BGA or a type of red algae?

 

[interex]

i donr know what bga is but its growing out of the rock and yes it is red

 

[darkjedv]

BGA = blue green algae...but its red. Its cyanobacteria not really algae. Are you able to blow it off the rock with a sea squirt or turkey baster? If it looks slimy then that's probably what it is. Usually from not enough water flow, over stocking, or over feeding. I'm having the same problem. Here's a link for more info. It might be what you have.

Depending on that answer, it could also be some red coralline or a red macro algae. If not cyano I would leave it alone and see what develops.

Has it got grape looking things on it, or does it plate off the coral? I have both, and I thin kthe grape one is a species of caulerpa. Its starting to spread alarmingly fast, and showing up in my coral colonies. Im going to have to scraping to do.
