Re: [APD] Green Water and Excel

["S. Hieber" <shieber at yahoo_com>]

Cyanobacteria are sort of a sort all their own, bacteria that photosynthesize -- perhaps protoalgae.  They don't show up positive with the Gram stain (they are "Gram negative") but one of the few Gram negative items that are susceptible to erythomycin anyway. Generally, Gram positive bacteria accumulate Eryth at much higher levels than Gram negative bacteria -- like 100 times -- but eryth does work on a few Gram negative bacteria and cyanobacteria.

Antibiotics like erythromycin work on BGA because it is really one of
several bacteria, not a plant.  Green water is treated as Tom and others
have suggested.

That said, the only time that I've had green water in the last decade was
when I accidentally overdosed Flourish by a factor of 100 or more (the
bottle overturned).  The green water lasted for four days and then
disappeared on its own.
The aquarium was newly set up and well planted, so the plants probably were
responsible for the demise of the algae.
