Green Monti Cap, has odd brown stuff on it.

My green monti cap, I have noticed of lately has this little brown stuff hanging off of it. Its in nice decent flow, this stuff looks like some kind of algae? The flow it is in its blowing all over but seems to not want to let go of the monti. I have no idea what it is? Params are all on target and stable. I don't know if they are dead polyps, the area that seems to have them are in really high flow.

 

Looks like cyano or possibly ejected zooxanthellae.

 

Yeah I think it might be zooxanthellae. I moved my vortech a bit so it was not getting so much flow on it. Hopefully that helps.
