I had a patch of it for months. Then after I bought my emerald crabs, it was gone within a week.

<font size="2" face="Verdana, Helvetica, sans-serif">I also got 3 emerald crab to take care of a few valonia algae...but the little bugger dont seem to be interested in it!!! and they dont take care of the brown patches either....I'm really starting to dislike their lazyness!!!!

thanks for your help..Marco
