Nitrofurazone Flake delivers broad antibacterial coverage through food — both gram-positive and gram-negative, useful for visible bacterial issues (fin rot, body sores, columnaris) where you want to treat without dosing the water column. The yellow-orange medication stays in the fish; biological filtration unaffected.
Active ingredient: nitrofurazone, impregnated in flake form. Fed as sole food source for 7-10 days. Pairs with kanamycin or erythromycin for layered coverage. For exact feed schedule, see the Antibiotics tab on our Medication Dosing Calculator.
Treats: fin rot, body fungus, external bacterial infections, columnaris, body sores.
Use in: quarantine, hospital tank, or display.
Reef safe: yes — antibiotic stays in the fish, not the water.
