Slime / Film on Porites

[usmcmarc]

I noticed some air bubbles on my porites (xmas tree rock) and I usually take my squirt feeder and gently blow them off with a squirt of water. So, I did that today and a film blew off the porites. It was covering the whole thing. I gently blew off all of the film with the baster and it floated all around the tank like cobwebs. The fish would eat it and spit it out. I fed all the corals yesterday. Is this a byproduct of feeding? Or maybe a slimetrail from my abalone crawling over it?

I use to have a porites xmas tree rock that didnt have the worms in it but was covered by mushooms instead. The porites would have a film over it sometimes that would come off and float around. Maybe it's just natural? I sold that rock to the lfs but I wish I had kept it.
