Hi Erin;

It's pretty weird stuff isn't it? A bacteria that looks and grows like algae. Yuck! Below is a link to a page by a guy that had success using Nifurpirinol to kill it. He grows algae in his tanks on purpose and tests them. Nifurpirinol is the main ingredient in a product by Aquarium Pharmaceuticals called "Furan 2". Most fish stores should have it ;
