algae on SPS

[Surgeonfish1]

I had a couple of SPS bleach they have some algae growing on them - light brown spot.

If I leave it will it overtake the live part of the coral or will the live part over take it?

What to do?

dude if there is algae already growing on your coral thats a bad thing. try to increase flow so no algae will settle on it, and address the root problem for coral bleaching. i had a similar prob when i put too much rowaphos in at once. coral bleached and algae grew on tips that had died off. pretty soon the rest of the coral joined club merph as well. hope this helps. good luck with that.
