Clean algae from zoa frag

[lastlight]

I was never able to beat the algae and it choked the zoas. I tossed the frag but as luck would have it there was some on another rock I didn't see. It's now weaving it's way into a few rocks. I've beat my hair algae and 95% of the anullata just to have other types take off. Fun

I will add that I tried a 100% peroxide dip before giving up and the algae and zoas both lived. I have a yellow and naso now and they do a great job on a variety of algaes but not this stuff yet.
