3. If these levels are needed, then clearly the organic level is too high and needs to be reduced by pond cleaning and/or water changes before treatment. Dip fish into solution for 5 minutes. When Potassium Permanganate is added to the water, it will turn the pond a bright purple at first, followed by pink champagne like color. Common treatment rates are 2 parts per million (ppm) or milligrams per liter (mg/L) for an indefinite pond application or 10 mg/L for a 10-minute tank treatment. Potassium permanganate, KMnO4, is a chemical oxidizing agent that will react with any organic matter in a pond including algae, bacteria, fish, particulate and dissolved organic, and organic bottom sediments. A walk through on how I use Potassium Permanganate in my fish room. o Shake well to dissolve crystals fully • Pour 5-10 ML at a time into tank. Pond volume is measured in acre-feet (surface acreage multiplied by the average water depth in feet). * Potassium permanganate can kill algae. As with many disease treatments, potassium permanganate is not really a medicine. If too much hydrogen peroxide is used the unreacted residue action may prevent further potassium treatments for a day or two, so it is best to only use hydrogen peroxide at the conclusion of a treatment. A slower, but just as destructive reaction is rust, in which iron is oxidized. You have estimated a pond to be 5 surface acres, and the pond has an average depth of 5 feet. It will react readily with any organic matter. per litre. The chemical mixture can be applied by means of a submersible pump or gravity fed from the container into the prop wash of the boat motor. If fish do not respond to treatment, reevaluate them to confirm the diagnosis. It can be neutralized by adding hydrogen peroxide. Make sure that the entire plant is immersed in the solution so that it becomes sterilized. 2. With regard to ornamental fishponds, it is mainly used in koi ponds because of dosing difficulties in heavily planted ponds. Example: 67.5 lbs of potassium permanganate × 2 = 135 lbs of potassium permanganate to obtain a concentration of 2 mg/L in the pond. perm. The test treatment that has the slightest faint pink color after 15 minutes is the correct 15-minute potassium permanganate demand. Another method to estimate the amount of potassium permanganate required for effective treatment is to determine the potassium permanganate demand or amount of chemical required to react with all the organic matter in a water sample. Wear gloves when using potassium permanganate as it will quickly react with the skin leaving a nice deep brown colour that looks as if you smoke about 100 a day. I vaguely remember purchasing this as a dip, but I don't remember actually using it. To kill adult leeches on plants, you’d use potassium permanganate, at 5mg/l. While hydrogen peroxide is not exactly an ideal way of dealing with pest snails on aquarium plants, a potassium permanganate dip or bath will get the job done. The 4 mg/L treatment is therefore the 15-minute demand. 4. It is only this residual level that will be effective against bacteria and parasites such as Costia, Trichodina and flukes. If preparing your own (dry) Potassium Permanganate treatment, use 2 ppm per liter of water for in tank (pond) treatments and up to 10 ppm per liter for 10 -30 minute baths. This means that dissolved Mn is found in the storage tank, oxidizes with the chlorine and causes turbidity. Collect five 1-liter samples of the pond water. Overestimating water volume can result in a greater-than-desired concentration of chemical, and may injure or even kill fish. A series of 1-liter pond water samples was treated with potassium permanganate stock solution. Determining the average depth for ponds with uneven bottoms and widely varying depths requires measurement of water depth at multiple locations in the pond using a simple grid or zig-zag sampling approach, in which all areas of the pond are measured. Have your fish properly diagnosed and carefully consider the cost. If, however, the residual level is too high, then it is likely to be harmful and possibly fatal to fish. For this reason potassium treatments will not be effective in green water. by Andrew M.

Cleaning fresh food of fish. Clearly, the level of dissolved and particulate organics will vary considerably from pond to pond – dependent on many factors. 5 ppm = 5 mg / litre, mg / litre  x 3.785 = mg / gall (US)           i.e  5 mg / litre = 18.9 mg / gall (US), mg/ litre x 4.546 = mg / gall (UK)            i.e  5 mg / litre = 22.7 mg / gall (UK), To convert imperial gallons to US gallons multiply by 1.2, The first is to calculate the organic level of the pond water by adding 0,1,2,3,4,5,6,8,10 mg of pot.perm. If the pot. Potassium Permanganate is effective for treating gill flukes in Discus Fish as well as other bacterial and fungal infections. In our hatchery we have a 200-gallon system and based on my measurements, we use … I dropped the dosage to this level after repeatedly getting in trouble with fish stress at the recommended 4 PPM dosage. Wait 15 minutes. It will assist by killing bacteria and parasites in the gills. By bringing these foods Soaked in water with potassium permanganate about 0.5 gram per the water 1 liter, and soaked them about 10 - 20 min. 3. it should be mixed with water before use, and then applied evenly over the entire pond surface to ensure an effective treatment. For small ponds (less than one acre), application of the chemical can be achieved by first adding a small portion of the total amount of chemical required for treatment to water in a five-gallon plastic bucket, and then broadcasting this solution over the surface of the pond while walking around the pond. Underestimating water volume will result in an insufficient concentration of chemical, and retreatment would be necessary. It is a caustic alkali that, at high doses, can cause serious corrosion of delicate tissues such as skin and gill. 4. Precautions When Using Potassium Permanganate. Contrary to some reports, potassium permanganate does not add significant amounts of oxygen to water and can actually decrease dissolved oxygen concentrations by killing algae that produce much of the oxygen in ponds. If the water gets too murky between treatments (as would happen with a high organic content), hydrogen peroxide could be used to clear the water but it would be advisable to do a good water change before continuing treatments. Uniform application can be achieved by driving the boar over the entire pond surface. If there is a question as to which rate has a faint pink color, choose the lower treatment rate. It is a very reactive chemical, reacting with organic material. Have your fish properly diagnosed and carefully consider the cost. Although it will assist in the healing process, it will not, on its own, cure ulcers. 1. In addition to being an effective anti-parasite treatment, Potassium Permanganate can also assist with bacterial gill disease and bacterial disease such as skin ulcers. Your local Soil Conservation Service or County Extension Service Office can provide assistance in determining pond acreage for irregularly- shaped ponds. Stir until dissolved. Is there any common use … It is affected by sunlight, so treatments are best carried out in the evening, or on cloudy days. Against this particular parasite it would, in most circumstances, be my first choice. My own experience is that in most cases it is very effective against Trichodina, clearing the problem quickly. In fact, practically every living thing needs potassium to survive. Potassium Permanganate helps in removing organic build-up in tank water: it kills, parasites, algae, bacteria, and fungi. You should not add more than a total of 6-8 mg  to a pond during any course of treatment. This method works well when the chemical can be dispersed evenly over the entire surface area of a pond from the shore. Multiplying the 4 mg/L demand treatment by 2 gives a recommended pond treatment rate of 8 mg/L. Potassium permanganate is commercially available in crystal or powder form. Potassium Permanganate is a class of antioxidants that can release oxygen (oxidation process) so that it can kill germs (baktericidal). Keep the plants in the sterilizing solution for 30 seconds. Potassium permanganate is a useful fish disease treatment; acting against a range of protozoan parasites including Trichodina, Costia and Chilodonella, as well as monogenean flukes Gyrodactylus (skin flukes) and Dactylogyrus  (gill flukes). Repeat treatment every 3-4 days if needed for parasites. If not, re-dose the pond the following day with 1.75 mg/l and repeat this daily until such times that it does retain a pink hue for 4 – 6 hours. See the fish disease section for more details about specific parasites or diseases, ppm = mg/litre            i.e. Today, we’re going to talk about the infamous 30-day syndrome and how to prevent it using potassium permanganate. Add 2, 4, 6, 8, and 10 milliliters (mL) of the stock solution (prepared in Step 1) into the five 1-liter samples. It would not be my first treatment of choice for this condition unless there were serious parasite complications. We need to calculate a dose that will leave an appropriate residue (1.75 mg/litre) of unreacted manganate ion after any such reactions. Water should hold pink hue for at least 6 hours. That usually works, but I do a water change soon after. Potassium Permanganate consumes large quantities of oxygen during the treatment, so make sure the waterfall is running at all times. If the pond remains pink to purple in color for 8--12 hours, then an effective treatment is assumed to have occurred, and no additional chemical is required. As with any chemical treatment, it is crucial to accurately estimate the volume of water that is to be treated. In 2000, worldwide production was estimated at 30,000 tonnes.
