Acriflavine

Active Ingredient: Acriflavine Neutral (Acriflavina)

Acriflavine is an antiseptic and dye used in aquarium hobby for its bacteriostatic and antiparasitic properties. It binds to nucleic acids, preventing the reproduction of target unicellular organisms and bacteria. It is commonly used to disinfect fish wounds and protect eggs from fungal attack.

Indications

  • External Infections: Treats Oodinium (Velvet), Columnaris (mouth fungus), Fin Rot, and Saprolegnia fungus.
  • Egg Protection: Excellent for preventing fungal outbreaks on fish egg clutches during incubation.
  • Wounds: Promotes recovery of damaged skin after physical trauma.

Dosage & Application

  • Long-term Bath: Dose 2 to 3 mg/L (ppm) in the water column. Treat for 3 to 5 days, followed by a 50% water change and carbon filtration.
  • Egg Bath: Use 5-10 mg/L as a short 30-minute bath, or 1-2 mg/L continuous bath in the egg incubation container.

Safety Notes

  • Stains Water: Stains the water a strong yellow/green fluorescent color. Can be cleared with active carbon.
  • Toxic to Plants: Will severely damage or kill live plants; do not use in planted tanks. Use a hospital/quarantine tank instead.
  • Mildly Toxic to Invertebrates: Snails and shrimp are sensitive; remove them before dosing.
  • Light-sensitive; turn off aquarium lights during treatment for optimal efficacy.

Leaflet Extract

Acriflavine is a strong dye and will stain aquarium silicone and ornaments. Safe for most plants but can be lethal to snails, shrimp, and other invertebrates. It may cause temporary sluggishness in fish. Light deactivates acriflavine, so aquarium lights must be kept off during treatment.
