No they use flourescein

You can mix vitamin C (Ascobic ACid) you keep adding till it is murky brown - it is now Manganese Dioxide which is ok for waste disposal ...

Hi,
Funny, I used Potassium permanganate before to heal gold fish in the fish tank when they looked sick, and it worked. I don't have them anymore, they died of old age.

They used to use it to help heal horses' hooves (as in All Creatures Great and Small). It had its uses but antibiotics have taken over! mmm, not sure if that is such a good thing.
