Relentless Bacterial Bloom

[Randy Holmes-Farley Verified Community Expert]

Chemiclean contains erythromycin (a macrolide antibiotic) and erythromycin is effective against many bacterial species, but not all:

http://www.emedexpert.com/compare/macrolides.shtml

"Generally, macrolides are active against gram-positive cocci (mainly staphylococci and streptococci) and bacilli, and to lesser-extent gram-negative cocci. With the exception of Bordetella pertussis, Campylobacter, Chlamydia, Helicobacter, and Legionella species, gram-negative bacilli are generally resistant to the macrolides. Macrolides are also active against Mycobacteria, Mycoplasma, Ureaplasma, spirochetes, and other organisms.

But why are macrolides NOT very effective against Gram-negative bacteria? They have large hydrophobic molecules and cannot penetrate both the inner and outer membranes of Gram-negative bacteria.

Erythromycin has activity against gram-positive cocci and some gram-negative organisms (eg. B.pertussis, M. pneumoniae, L. pneumophilia)."

Any updates @Jimbo?

The bacterial growth seems to have slowed down. Still get a little bit of growth in the sump but not nearly as bad. Filter socks will clog within the first 24 hours of using one so there's still some bacteria growing. Still cannot figure out what's fueling it as i'm not dosing any carbon source.
