Will general cure kill off my beneficial bacteria? I do have a seeded back up filter...if I need it. Active ingredients: 250 mg Metronidazole 75 mg Praziquantel per packet. 1 packet treats 10 gallons.
I was trying to worm my discus. 2 of them kept rubbing against "objects" in the tank. They are new and I'm sure they were stressed out from being shipped.
