## Features

- Use biocides safely. Always read the label and product information before use.
- 【 ANTISEPTIC AND ANTI-BACTERIAL TREATMENT FOR KOI 】: Use when fish show symptoms of a bacterial infection, or as a quarantine solution before adding new fish.
- 【 TREATS FIN, TAIL & MOUTH ROT AND ULCERS 】: A powerful antiseptic, anti-bacterial treatment for mouthrot, tailrot and finrot. Acriflavin can also be used in conjunction with NT Labs Ulcer Swab and NT Labs Propolis Wound Seal for the treatment of ulcers and other open wounds.
- 【 EASY TO USE 】: To work out the required dosage for your pond, simply calculate the volume of your pond in litres (length x width x depth (in cm)/1000) or alternatively, use our Online Dosage Calculator. 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. Allow 7 days after medicating and perform a partial water change before re- treating or treating with a different medication.
- 【 EFFECTIVE ACTIVE INGREDIENTS 】: Koi Care Acriflavin contains Acriflavine neutral (80 mg/100ml). This ingredient makes it a powerful solution to treat bacterial infections in koi.

## Questions & Answers

**Q: How long is the green dye meant to last in the water i mean the colour**
A: I usually Leave it a day and then fill a glass with water from the pond. 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.
