高锰酸钾做为一种强效的杀菌消毒剂，虽然在食用鱼的养殖中用处不大，但是在热带鱼养殖上，还是一个很不错的消毒剂，肯定有很多鱼友都用高锰酸钾治好过鱼病，但是估计也有不少鱼友用过高锰酸钾加速了鱼儿的死亡甚至杀死过鱼。
下面我们仔细讲一下。
Potassium Permanganate as a potent bactericidal disinfectant, although useful in edible fish culture, but in the tropical / fish breeding, is a good disinfectant, there must be a lot of fish friends with Potassium Permanganate cured fish, but estimate there are many fish friends used Potassium Permanganate accelerated the death or even kill a fish fish. Below we carefully.
高锰酸钾消毒的剂量是万分之一，由于很难控制的很准确，我们只要将高锰酸钾溶解成为淡红色就可以（参考图片）。
慢慢地时间长了就有经验了。
溶解时不要着急一下放很多，因为高锰酸钾的溶解速度很慢。
给鱼消毒要最好先找个小容器化开最好，然后再消毒，一定不能直接投入缸中，以免被鱼误食。
消毒完毕要进行大换水。
Potassium Permanganate sterilization dose is 1/10000, because it is difficult to control the very accurate, as long as / we will Potassium Permanganate dissolved as a light red can (see picture). Slowly a long time there is experience. Don't worry a lot of dissolution of decentralization, because the dissolution rate Potassium Permanganate slowly. The best fish disinfection to first find a small container of the best, and then sterilized, must not directly into the cylinder, so as not to be eaten by fish. After disinfection to big water.
注意事项
Matters needing attention
1、水温要控制好。
不能高于28摄氏度，虽然水温越高高锰酸钾的有效时间越短，但是它的氧化性也越高，万一量大了，就会对鱼造成烧伤。
1, the water temperature control. Can not be higher than 28 degrees Celsius, while the effective time of the / water temperature is higher Potassium Permanganate shorter, but its oxidation is also higher, if the amount is large, it will cause burns on fish.
2、井水养鱼要谨慎使用高锰酸钾。
因为井水中的二价铁离子很多，可以被高锰酸钾氧化生成三价的氢氧化铁胶体，这种二氧化铁的胶体可以在鱼鳃上形成一种棕黄色薄膜，影响鱼鳃的气体交换。
2, the water the fish should be used with caution Potassium Permanganate. Because the two valent iron ion in well water, can be generated Potassium Permanganate oxidation of trivalent ferric hydroxide colloid, the two iron oxide colloid can form a yellowish brown film on the gills of fish gills, gas exchange.
3、充气设备不能停，尤其鱼的密度大的时候，由于高锰酸钾对鱼的鳃有一定的刺激性，会影响鱼鳃的氧气交换能力，所以要防止缺氧。
3, inflation equipment can not be stopped, especially when the fish density, due to Potassium Permanganate on the gills of fish have a certain irritation, will affect the fish gill oxygen exchange ability, so to prevent hypoxia.
4、用药时人不能离开，要随时观察鱼的活动情况，一旦反常情况(如乱窜、急游、不安)甚至有些病重个体失去平衡有死亡征兆，应立即换水，或只用其他药物解药。
People can not leave the 4, medication, activities should observe the fish, once the abnormal situations (such as running, swimming, anxious restless) and even some ill individuals lose balance have signs death, should immediately change the water, or with other drugs.
这里推荐一种可以解除高锰酸钾的药：双氧水（氧化氢溶液）。
因为它遇水后能迅速
放出大量的氧气（在鱼浮头的时候可以使用解救缺氧，也可以杀菌），与高锰酸钾发
生氧化还原反应。
双氧水可以直接往水里倒，要开启循环设备，还要避免直接倒向鱼体。
Here's a may terminate the Potassium Permanganate medicine: hydrogen peroxide (hydrogen peroxide solution). Because of its water quickly after the release of large amounts of oxygen (in the fish floating head can be used to rescue the hypoxia, can also sterilization), and Potassium Permanganate oxidation-reduction reaction. Hydrogen peroxide can be directly to water down, to open the circulating equipment, but also to avoid the direct backward fish.
其次，维生素C也对高锰酸钾有解除作用。
我们可将其研碎溶解于水后倒入浴缸内。
高锰酸钾失效后会变为沉淀，基本没有毒害。
Secondly, vitamin C also has beneficial effect on Potassium Permanganate. We will crush dissolved in water into the bathtub. Changes to the precipitation Potassium Permanganate after failure, no poison.。
