Kanamycin is the targeted antibiotic for gram-negative bacterial infections — the type behind most saltwater diseases. Aeromonas, Vibrio, Pseudomonas: the alphabet soup that causes ulcers, fin rot, and the popeye eye swelling that ends a fish if you do not catch it fast. Where General Antibiotic Cure casts a wide net, kanamycin is the specific tool when you have narrowed down what you are chasing.
Active ingredient: kanamycin sulfate, an aminoglycoside antibiotic. Standard QT course is daily dosing for 10 days with partial water changes between doses. Heavy on biological filtration — expect to recycle a hospital tank afterward. Pairs with nitrofurazone for combined gram-positive and gram-negative coverage. For exact dosing per gallon, see the Antibiotics tab on our Medication Dosing Calculator.
Treats: gram-negative bacterial infections — Aeromonas, Vibrio, Pseudomonas, ulcers, fin rot, popeye, septicemia.
Use in: quarantine or hospital tank only.
Reef safe: no.
