I have heard that some antibiotics can be used to control algae (
cyanobacteria actually ) .

Which antibiotics will kill off the cyanobacteria without hurting the
beneficial nitrogen cycle bacteria ?

TIA ;

In the tanks that I used erythromycin in the form of E-Tabs, I had no
issues with my Bio-filters declining. The Krib has some data about this.
