my zoa is starting to get this brown scum on it. its like a hair algae or something, im not really sure. wat should i do?

pics would help, brown scum could be either cyano or a fungus..

oh hirs a picture sorry about that

Does it stay closed all the time or does it occasionally open? Nice whammins btw!

Iodine dip and moderate flow should take care of it, furan in the dip would help if you have some. It's a powdery brown bacteria that's generally caused by shipping stress and low flow, how long have you had them?
