Thanks for the clarification Meph . I had a form of black "algae" /
cyanobacteria and Erythromycin cleared it up. I assumed ( incorrectly ? )
that his "algae" is the same stuff. Some good info...

KEITH,
Erythromycin will NOT kill algae. It will, however, kill some
varieties of cyanobacteria, which are sometimes referred to as "blue-
green algae", though it is not algae at all, but a form of bacteria.
(Its only similarity to algae is that it has chlorophyll and can
therefore convert light into energy). Moreover, since erythromycin
is an antibiotic, you must be careful when using it lest you create
bacterial strains that are resistant to it.

Cyanobacteria is characterized by growth in undifferentiated sheets.
No plant like leaves or hairs will be visible.

Meph

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...
