Koi Forum • malachite green and salt at same time? : Koi Talk


2 of my fish have a fungus on their mouths. i have administred at topical malachite green treatment into the ponds water having given the fish a bath in a more concentrated does before retirning them to the pond.

I know its not really the time of the year for topical water treatments but i thought a dose into the pond might prevent spread of any infections.

Can salt be administered into the water at the same time. i am reluctant to be adding too much to the water. My current thinking is to bathe the fish in a salt bath and return them into the malachite green treated water.
