Fish Egg Surface Disinfectant

  • Conditions such as the organic content of the water and the mass of the fish eggs vary, thus the number of eggs treated will vary.
  • Place eggs into a 100 ppm free iodine solution of Ovadine for ten minutes. A suitable ratio is 1 volume of eggs to 4 volumes of this solution.
  • A 100 ppm free iodine solution is made by diluting 10 ml Ovadine to 1 litre with clean water.
  • Rinse eggs with clean water

*If you are unfamiliar with fish egg disinfection, we recommend that you first consult with your local fish health professional.

General Sanitizer

  • A 250 ppm available iodine solution is made by diluting 25 ml Ovadine to 1 litre with clean water. Use as a dip or bath.
  • Wash items that are heavily contaminated with soil or organic debris before disinfecting with Ovadine.
  • A change in the solution colour from dark brown to light yellow indicates loss of activity. Ideally, the free iodine concentration should be monitored during treatment. Renew by using a fresh solution of Ovadine. 

Storage: Store at room temperature between 15°C and 30°C (59°F and 86°F). Protect from direct sunlight.
