Is there a website out there with info and pictures of different kinds
of algae in aquaria and how best to treat each kind? I seem remember
something like this, but can't seem to find it.

If there's not one, maybe someone here can help me. I've got a kind of
green flim algae that covers my hygro, dwarf sag, tank walls, and
gravel, but sword seems to be left alone by it. It's got the color of
java moss, but grows in a film. Anyone have any ideas?

thanks,
