NT Labs Acriflavin - Your Solution for Fish Bacterial Infections and Wound Care

Ensure the health and well-being of your Koi with NT Labs Acriflavin, a trusted remedy designed to effectively treat fin, tail, and mouth rot, as well as ulcers in your fish.

When to Use: Utilize Acriflavin when your fish display symptoms of a bacterial infection, or as a proactive quarantine solution before introducing new fish to your aquatic environment. This versatile solution can be combined with Ulcer Swab and Propolis Wound Seal for comprehensive treatment of ulcers and other open wounds.

How to Use: Maintain the optimal water quality using NT Labs Test Kits before beginning treatment. Mix the appropriate dosage in a clean bucket of pond water, then evenly distribute it over the pond's surface. Allow the solution to work its magic for a period of 7 days, remembering to turn off UV filtration until the water color returns to normal. Ensure proper aeration throughout the treatment duration.

If a repeat dosage is deemed necessary, consult the NT Labs Diagnosis Tool to confirm the condition, as a different medication may be more suitable. After medicating, wait for 7 days, perform a partial water change, and then re-treat or switch to a different medication if needed. Always schedule treatments when you have time to observe your fish and respond promptly to any unexpected reactions.


  • Do not use Acriflavin at water temperatures exceeding 30°C.
  • Avoid application in hot, humid, or thundery weather.
  • Never mix medications to ensure the effectiveness of the treatment.

Active Ingredients: Acriflavine neutral 80 mg/100ml
