The tank has a blue-green algae scourge that I can't get rid of. Is it safe to give it a dose of erythromycin, or will that hurt the babies? In the algae section of the Krib it suggests dosing with 200 mg/10 gals but I haven't been able to find any info regarding the effect on fry. I also have a 20g with moss that's slightly tinged with it, and I'd like to nip that one in the bud.

If you make regular 40-50% water changes every other day, which are anyhow beneficial to the fish, the problem will most likely go away within a few weeks.
