Aqua Meds KanaRx (Kanamycin Sulfate)

Aqua Meds · Koi & Goldfish Medication KanaRx — Pure Kanamycin Sulfate The deep, broad-spectrum antibiotic you reach for when an infection has moved past the early stage.

Treatment coverage (therapeutic) Size Approx. pond volume 100 g ~400 gallons 250 g ~1,000 gallons 500 g ~2,000 gallons When KanaRx makes sense A fish is going downhill or not responding to earlier treatment. You suspect a deeper or internal bacterial infection. Visible infections aren't improving with NitroCure or KoiCure. You need a treatment that works even when fish won't cooperate. Where it fits: KanaRx is the step-up, not the first move — start with NitroCure or KoiCure, and escalate to KanaRx for serious or internal cases. Can also be mixed into medicated food. Follow label directions for dosing & schedule. Guidance only — not veterinary advice. Part of the Aqua Meds koi-health line. Targeted formulas for parasites, water quality & pond biology.
