how do i get rid of Cladophora????

[1diverdown]

i've got clumps of this annoying stuff everywhere. unfortunately, i don't have a camera that can focus down far enough for a picture, but if you have Sprung's Algae: a problem solver guide, it's on pg 49 top left. this stuff is dark green, wire-like algae, that is tough as h*** to remove from rocks. other than using scissors, it just doesn't come off. i have mithrax, a huge naso, a purple and 4 yellow tangs and nothing touches this stuff. anyone know of anything that will eat this?

thanks,
Doug
