Permission to translate the FAQ was obtained, and even encouraged. Use required eye protection. The colder the water, the safer, cold water has a greater ability to dissolve oxygen. Day 1 – Add the proper dose of potassium permanganate to the pond. for many years in fish culture. Potassium permanganate is good for treating external protozoa and external bacterial infections (Plumb, 1992). Aeration (or lack thereof) makes the difference whether the treatment kills the fish or the parasites. Determining the Amount of I will not go too much into details, except to say that this is chemically impossible. The demand If you can accurately weigh the PP, and you know the pond contend within a 10% margin, then the use of PP is almost without risk. Not only beginners but also "pros" have frequently misjudged the situation. People who are carefree, not accurately weigh, or roughly estimate the pond volume, or think "the more the better", will be better off with other medication. P.

This is the best method, while ensuring proper dissemination and aeration. At the least, the first few times the fish welfare should be checked every fifteen minutes. In this case one can re.

KMnO4 is a useful treatment against most types of parasites in a pond. The 15 minute potassium permanganate is DEMANDED.

Thou shalt have truckloads of NPC and hydrogen peroxide at hand. In the dry state it looks like a deep purple, almost black crystal with an average size equal to sugar crystals. The use of KMNO4 to increase oxygen concentration in O2 depleted pond water KMnO4 makes a strongly staining purple solution (you can end up with purple fingers) when dissolved in water. It is used as a regeneration chemical to remove iron and hydrogen sulfide (rotten egg smell) from well water via a "Manganese Greensand" Filter. So use gloves.

If you would have followed the instructions in this document, you would have never had to deal with this problem. Short-term laboratory tests do not adequately predict effective potassium permanganate (KMn0 4) treatment rates for fish culture ponds.In pond water samples with high concentrations of organic matter (COD > 50 mg/L), the previously recommended disease treatment rate of 4 mg/L KMn0 4 plus the 15-minute KMn0 4 demand did not result in a KMn0 4 residual lasting more than 2 hours. PP has an unlimited shelf life and can not spoil. You do not have to be afraid, but you should also not use it as a remedy for all diseases in the pond.

Destain the water with hydrogen peroxide (H2O2), 52 ml / m³ or NPC. not necessary to do a 15 minute demand study, when a high dosage KMNO4 dip Again, this is about light influences. KMnO4 (henceforth PP), unlike malachite does not contain toxic components that can accumalate in the fish, its use is permitted in fish farms for human consumption. The PP solution should be distributed as evenly as possible across the pond to avoid high dose clouds. r safety reasons, I would strongly advise against nocturnal dosing. potassium may be legally used only if there is a current Investigational PP kills the skin, and will stain it dark brown for several days. 30 - and 37% solutions are available in pharmacy and suppliers of laboratory equipment.

Wait a minute for the color to stabilize. Also, this dose is best applied through the spraybar pump to the pond.

Thou shalt never leave a PP treatment unattended. Aeration is the key to long-term survival of biofilters for treatment (6-8 hours). treatment is used.
