RE: [GSAS-Member] Removing difficult algae from acrylic tanks

["matt kaufman" <igotadose@hotmail.com>]

Have you tried simple fiberglass filter floss, the kind that is used for box 
filters? It's what I used to use in my acrylic tanks and it seemed to work 
well enough. Sounds like you might have a real green algae rather than the 
typical blue-green "algae" that's a cyanobacter.

As for recycling the tank, just bring it to one of the GSAS auction meetings 
and I'm sure someone will want a cheap 125 gallon tank, scratches or not.
