Green algae question

[cherokee_dude]

So, I've got this one frag (20 polyps) of zoas that is now pretty much covered in green algae and the polyps are closed up...
It's the only one and I can't figure it out.

I did an 3 minute 30% iodine dip, followed by a 3 minute FW dip and shakeout, then the same 3 minute iodine dip. No change

Any other treatments I could try? Can I do a full strength iodine dip maybe?

No hair algae in the tank.

Still need help peeps! Any thought?

Maybe a dip in tech-m?

ive had the green algae on zoos before, when i didnt really have much algae in the tank to speak of.
i did do the same iodine dips etc. didnt seem to make a difference. i ended up taking them out of the tank and sort of brushing off the algae (with a tooth brush)and wiping at it witha paper towel. i did this fairly often. it did go away.
the only other treatments i can think of is furan... but dont know if that would help any....
