Coraline Algae for sale?

[robbyville]

Hi all,

Check out this link... a fellow on ebay selling scrapings of coraline? I have never heard of this before but am curious as to the suggestion that having coraline limits the amount of nuisance algae.

Does anyone know if this is true? We are having some problems with hair algae that does not seem to go away. But we have recently scraped off some of the coraline from the back of our tank...could this possibly be contributing to our hair algae problem?
