RE: erythromycin and fry - treating blue green algae

["Brett Kemker, PhD" <bkemker@mailer.fsu.edu>]

Susan-
Like Gary, I too have used changes in photoperiod to eliminate blue green
algae.  If this does not work, I think I would remove as much as I could
manually.  I do this by spinning a small twig from a tree in the blue green
mass (cotton candy style).  I don't think that antibiotics should even be
considered, as the blue green algae do not pose a threat to the fry.  IMO
the fry should be the primary concern not aesthetics.

Susan,
I know this sounds simplistic, but on three occasions I have eliminated blue
green
algae from 'horror' tanks by turning off the lights and leaving the tanks in
at most
half light from the room. The complex plants survived the two week 'cure',
and the
tanks are now flourishing. Attempts to use antibiotics in the past didn't
really work
for me.
