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 ### ⭐⭐⭐⭐⭐ Help cure sores on Koi? *by D***D on 12 September 2026* Packaged well, quick delivery.
