    水里有什么对观赏鱼有害?

    ammonia

    氨是一种来源途径比较广泛的有害物质,主要来源有三个,1.鱼类表面的粘膜。鱼类表面那层滑滑的粘膜其实是一直在不断的新陈代谢,新的长出来后,旧的粘膜就会直接脱落,这些脱落的粘膜就会产生氨。2.鱼类粪便。鱼类一生都处在吃喝拉撒的状态里。拉出来的鱼粪就会产生出氨。3.食物残渣。每次喂鱼的时候是绝对会有食物残渣掉落的,他们也是氨的来源。氨在偏酸的水中毒性是比较小的,而在碱性水中,毒性就会越来越大。鱼缸中氨的含量最好不要超过0.05了,如果你鱼缸中氨含量达到了0.2,很快鱼缸里面的鱼就会全部都去世。

    上海11选5Ammonia is a kind of harmful substance from a wide range of sources. There are three main sources. 1. The smooth mucous membrane on the surface of fish is actually constantly metabolizing. When the new one grows out, the old mucous membrane will directly fall off, and the falling mucous membrane will produce ammonia. 2. Fish manure. Fish are in the state of eating, drinking and pulling all their lives. The pulled fish manure will produce ammonia. 3. Food residue. Every time I feed the fish, there will definitely be food residues falling. They are also the source of ammonia. Ammonia is less toxic in the water with partial acid, but more and more toxic in the alkaline water. The ammonia content in the fish tank should not exceed 0.05. If the ammonia content in your tank reaches 0.2, all the fish in the tank will die soon.

    亚硝酸盐

    nitrite

    我们都知道,鱼缸中存在着一种人人皆知的益生菌,它便是硝化细菌。此处的“它”应该改成“他们”,为啥?硝化细菌实际上是两种细菌的统称,一种是硝酸菌,另外一种就是亚硝酸菌了。氨主要被亚硝酸菌吃掉。然后亚硝酸菌就会将氨给全部转化成亚硝酸盐。是的,亚硝酸盐就是这么来的。亚硝酸盐对鱼也是有毒的,所以这个东西还需要有其他细菌来将其转化成毒性较小的物质,这就需要硝酸菌来帮忙了。

    We all know that there is a well-known probiotic in the fish tank, which is nitrifying bacteria。 Here "it" should be changed to "they"。 Why? Nitrifying bacteria is actually a general term for two kinds of bacteria, one is nitrobacteria, the other is nitrobacteria。 Ammonia is mainly eaten by nitrous bacteria。 The nitrous bacteria then convert all the ammonia to nitrite。 Yes, that's what nitrite comes from。 Nitrite is also toxic to fish, so it needs other bacteria to turn it into less toxic substances, which needs the help of nitrobacteria。

    硝酸盐

    Nitrate

    硝酸菌会会将亚硝酸菌转化出来的亚硝酸盐给吃了,然后再将其转化成毒性较低的硝酸盐。硝酸盐其实就是这三种有害物质中毒性最小的一种有害物质了。不过,硝酸盐一副人畜无害的样子,真的对鱼没有伤害吗?不不不,这种物质其实是微毒的,在含量少的情况下硝酸盐不会对生物进行攻击。但是如果一旦硝酸盐超标了,你这缸水就已经不再是可以养鱼的水了,而是毒害鱼类的“反水”!反水是没法养鱼的,一旦鱼缸的水变成反水,无论适应能力有多强的鱼类,都会毫不犹豫,立马嗝屁。

    The nitrobacteria will eat the nitrite converted by nitrobacteria, and then convert it into less toxic nitrate. Nitrate is actually the least toxic of the three harmful substances. But is nitrate really harmless to fish when it looks harmless to humans and animals? No, no, no, this substance is actually slightly toxic, and nitrates will not attack organisms in a small amount. But once the nitrate exceeds the standard, your water is no longer the water for fish farming, but the "backwater" that poisons fish! There is no way to raise fish by backwater. Once the water in the tank becomes backwater, no matter how adaptable the fish are, they will immediately burp their farts without hesitation.

    最后,硝酸盐还得通过自己勤勤恳恳的换水,才可以将硝酸盐的含量降低下来。太久不换水,硝酸盐积累得越来越多,很快就会超标。养鱼,换水是必须要进行的一项工作。那么,该如何做才能预防这些有害物质超标呢?我们一步一步来。

    Finally, the nitrate content can only be reduced by the diligent exchange of water. If we don't change water for a long time, more and more nitrates will be accumulated, which will soon exceed the standard. Fish farming and water change is a must. So what can we do to prevent these harmful substances from exceeding the standard? We come step by step.

    解决氨的问题

    Solve the problem of ammonia

    氨的主要来源是由于水中的杂质产生,而这个东西产生后就需要细菌去将其转化成低毒一些的物质。所以,你首先就一定要具备一个足够强大细菌种群,同时生化过滤的作用需要与鱼缸中饲养的鱼类成正比。鱼多了细菌也忙不过来。氨这块问题解决好了,剩下的就是硝酸盐了。硝酸盐只能靠人为的换水去降低其含量。

    The main source of ammonia is produced by impurities in the water, which need bacteria to convert into less toxic substances。 Therefore, you must first have a strong enough bacterial population, and the role of biochemical filtration needs to be proportional to the fish in the tank。 There are too many bacteria in the fish to help。 The problem of ammonia has been solved, and the rest is nitrate。 Nitrate can only be reduced by changing water artificially。

    上海11选5所以,保持鱼缸水质健康,单单有强大的物理过滤是不够的,还需要强大想生化过滤,以及每周一换水的操作,这样以来,可以降低很大的死鱼风险。

    上海11选5Therefore, to keep the water quality of the fish tank healthy, it is not enough to have a strong physical filter, but also a strong biochemical filter, as well as a weekly water change operation, so that a great risk of dead fish can be reduced。
