An antibiotic will always be more effective and complete at eliminating a bacteria than an oxidizer.

i could not fix it no matter what i did, clean gravel, H2O2, blackout etc you name it, even Erythromycin was once failed to kill it, but am going to try Erythromycin one more time and hoping this will kill it.

Just remember that Erythromycin will not distinguish "bad" bacteria from "good" bacteria. You will be killing off part of your beneficial population, so dose carefully.

Daily 25% water changes for a week or so have always worked for me.

One of the reasons erythromycin works and the other 2920945+ antibiotics don't is because it is effective on gram positive bacteria. Your bio filter is safe. Just follow the directions and do the COMPLETE course as you normally would for a fish infection.
