I've been doing some research and I'm trying to understand why I've been reading about people using a combination of PraziPro and Metronidazole when General Cure has both Praziquantel and Metronidazole. Is General Cure is less effective? I've also been reading about people putting GC in food when the directions tell you to just dose the tank. Is GC more effective if fed to the fish? I appreciate any incite on the matter.
