NT Labs Acriflavin
NT Labs Acriflavin is a treatment for bacterial ailments such as fin-rot and ulcers in Koi ponds or quarantine tanks. NT Labs Koi Care Acriflavin is best used in conjunction with NT Labs Ulcer-Swab and Wound Seal in the treatment of ulcers and other open wounds. When added to the pond, NT Labs Acriflavin will reduce the numbers of these opportunistic bacteria in the pond, thus lowering not only the chance of infection, but also the intensity of disease in already infected ponds. Acriflavin is ideal to use in hospital or quarantine tanks, but it is unwise to constantly add the treatment to the pond when the fish are healthy. This is because a background level of bacteria is essential for healthy fish to maintain their immune system.
Dosage Rates:
- 250ml – Treats 9000 litres / 2000 gallons
- 500ml – Treats 18000 litres / 4000 gallons
- 1 Litre – Treats 36000 litres / 8000 gallons

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.
Warning:
- 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.
