Aquaetic Potassium Permanganate Solution 4 Oz

As advertised

Imported about a dozen big koi from Japan, and they showed signs of flukes by flashing and scratching on pond floor once I set released them. So I moved them to a 400 gallon intex pool, and treated it with this PP solution as directed, the pink faded quickly, so I repeated the process, this time adding a little more every time the water was fading slowly, kept it pink for about 6 hours total, probably extreme but it worked. Then cleared the water with hydrogen peroxide and inspected the koi. No more flashing or scratching. Back to the real pond they go. Cant complain, I prefer using the PP powder if I have access to it however.

There's no dosing instructions for fish tanks had hard time figuring out dosage for fish tanks . I have large fish room will Last me very long time 20g tank dosage is .8ml container is 125ml. Works very well good luck

Best stuff to take care of my little pond.
