I received some Kordon Permoxyn today. It is 3.84% Potassium Permanganate
Permoxyn’s instructions say this;
To use as bath for diseases caused by external protozoans and crustaceans from fishes,use a 10 ppm solution (2 teaspoons [10 mL] of Permoxyn per 10 gallons of water) for 30 minutes. Discontinue use any time that fishes show undue stress.
To use for Bacterial Gill Disease remove carbon and clean the outside filter. Return the filter to use without the carbon. Add 1/2 teaspoon (2.5 mL) of Permoxyn per 10 gallons of water to produce a concentration of 2.5 ppm. Do not exceed the recommended dosage. After 4 consecutive days make an extensive water change of one half or more of the water volume.
Amdrew Soh says this;
200mg to 100 liter of water
pH best to be below 7 but even at 7 plus, it is still safe though a little stressed.
Temperature maintain @ 25 to 28 during treatment. Never bring up the temperature.
After 24 hours, make complete water change. Never leave the residue of potassium permanganate, after oxidized, for 3 days to a week as that may be toxic and sensitive discus may die from it. 24 hours is extremely safe.
2 to 6 hours treatment is insufficient.
Total treatment suggested is 3 times in a week.
(Note: Both above statements are somewhat paraphrased)
Andrew Soh’s 200mg/100l = 2mg/l = 2 ppm is pretty much inline with Kordon’s 2.5 ppm
However Kordon says to treat for four consecutive days at 2.5 ppm and Andrew says this may kill weaker discus.
My question, (finally, I know) is “At what dosage and for how long should I be using PP?” Also has anyone tried PP as a dip instead of a bath?
