Bga What Dose Of Antibiotics?

[mibson]

I have a green film on my glass that is VERY hard to scrape off, is it BGA? I think it is..

I also heard that a low dose of antibiotics can destroy the BGA without seriously harming your "good" nitrogen bacteria in the filter, what dose is that?

I have erythromycin and tetracycline, which is better for this?

Thanks so much!

The hard algae is green spot algae so antibiotics wont kill it. BGA is very soft and easy to remove. A stanly knife blade does a good job of removing it from glass. Just be careful not to get scratches on the glass.
