Re: NFC: Blue Green Crud

here is what the krib said in part about blue green
Blue-green, slime or smear algae
Grows rapidly in blue-green, slimy sheets. Spreads
rapidly over almost everything and usually indicates
poor water quality. However, blue-green algae can fix
nitrogen and may be seen in aquariums with extremely
low nitrates. Sometimes seen in small quantities
between the substrate and aquarium sides. Will smother
and kill plants. 
This is actually cyanobacteria. It can be physically
removed, but this is not a viable long term solution
as the aquarium conditions are still favorable for it
and it will return quickly. Treatment with 200 mg of
erythromycin phosphate per 10 gallons of water will
usually eliminate blue-green algae but some experts
feel it may also have adverse effects on the
biological filter bed. If erythromycin is used for
treatment, ammonia and nitrite levels should be
carefully monitored.
