Sally Kelly –
Used E.M. Erythromycin when my fish developed blood spots and body slime. The treatment worked quickly. No water discoloration and the fish showed improvement within a few days. Works well with my existing Ich treatment.
Paul Bell –
Felt it helped control the gill infections in my saltwater tank. Easy to mix and no color change in the water. A reliable option for bacterial issues.
Sally Greene –
My fish had open sores and mouth fungus. After using this powder, the symptoms cleared up. It’s effective and safe to use with other medications.
Vanessa Parsons –
It worked for mild slime issues, but not for severe Furunculosis. Might need to combine with other treatments for serious cases.
