Erythromycin will kill most kinds of algae without damaging your nitrogen
cycle. Treat with Erythromycin for 5 days, then do 30 percent water changes
for at least 3 days. Don't forget weekly water changes or it will likely
come back again.

The main causes are overfeeding and insufficient water changes. The kind I'm
talking about is slimy but looks fuzzy, and is about 1 cm / 0.5 inches
long. That %#*! stuff grows on almost everything, glass, plants, rocks,
the shells of snails if you don't get it under control.

Might sound stupid, but does it have exposure to natrual light? I have
had
this as well, ( looked like black angel hair ). I don't think I did
anything
to rid of it, if I remember correctly, it disappeared on its own.. I seem
to remember somewheres, it was suggested the lighting had something to do
with it.. Perhaps someone else has an idea...
