[RML] Algae ? Question

Hi all,
I'm new here, but not to Australian native fish. May I ask your advice?
I have a 4 foot tank of natives. Plants are Elodia (sp?). Temp at 28. pH at 7.
40 W lighting for 10hrs/day. On my rocks is a tufted very dark green algae
that seems to be seasonal - at the moment I think it's dormant. Recently I
have been plagued by a black slime that starts off looking like very dark
green dust on the glass, but it soon covers the plants and rocks. It doesn't
seem to respond to erythromycin, so I guess it's not blue-green algae
(cyanobacteria). It has no smell either. Any idea what it is, and how I may
get rid of it. I'd like to keep the tufted algae if possible. Would prefer a
biological solution rather than chemical.
Thanks
Andrew
