Review: A treatment that helps fish recover. - Acriflavine is more of a antiseptic medication, I used this a couple of weeks after treating the koi for fluke. A couple of the fish had scratched themselves, a couple of others' mucus coating looked messy because of fluke in their death throes, the acriflavine helped these issues. The treatment wasn't overly expensive, it's easy to add to the water, it's not an ultra strong treatment, so it's pretty safe for the fish. It did exactly what I wanted it to do and the fish look fighting fit again. Review: Help cure sores on Koi? - Packaged well, quick delivery.

Mix the appropriate dosage in a clean bucket of pond water, pour evenly over the surface of the pond and leave for 7 days. Switch off UV filtration until the colour has gone from the water. Aerate the pond well during treatment. If you feel a repeat dose is necessary, check your diagnosis using the Diagnosis Tool; a different medication may be more suitable.

If it is clear, I turn the UV back on (it is usually clear). **Q: Can this be used in winter?** A: I personally do not apply any treatment if the pond water temperature is below 10 Celsius. Under the FAQ section of NT Labs Koi Care - Acriflavin it states: "The minimum "effective" water temperature when applying a treatment/medicine is 10 degrees Celsius. At lower temperatures, everything happens more slowly. Below this temperature treatments may be less effective. Please note that ALL fish keepers have a duty of care to the fish and it may be necessary to treat anyway." **Q: Can this be used same time as fmg please?** A: Not sure what FMG is? But it's not recommended to use anything else at the same time **Q: How much do i use in 100 gallons** A: You need to use 10 ml of product t 80 imp gallons. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A treatment that helps fish recover. *by G***K on 23 September 2026* Acriflavine is more of a antiseptic medication, I used this a couple of weeks after treating the koi for fluke.
