有什么方法可以防止金鱼死亡？

金鱼（详细介绍）

金鱼是我们养殖的最具观赏性的鱼。虽然养殖起来比较好，但是金鱼的死亡率还是比较高的。金鱼死亡的原因有很多。过度饱和喂养而不定期换水占很大比例。现在，让我们详细介绍金鱼死亡的原因，以帮助您更好地培养金鱼

1、水中的氯气

我不知道为什么不是每个人都知道这一点，但氯气可以在几天内杀死鱼。如果你住在城镇里，或者有水管而不是井，你的水会含有氯。氯可以杀死饮用水中的脏微生物和细菌，但也会杀死鱼！避免这个问题的最佳方法是将水放在一边几天（让氯挥发），或者购买净水器。净水器价格便宜，使用方便。它每加仑只需要几滴，但在使用前一定要阅读说明

2、过量喂食或缺乏氮气循环知识

1。水族馆的注意事项

当鱼被放入新的水族馆时，它们的鳃和排泄物会产生氨。氨和氯一样有毒，几天后会逐渐增加。此时，如果你立即将所有的鱼放入水族馆，氨会迅速杀死你的鱼。那么我们如何去除氨呢？它经过一个称为氮循环（有时称为氨循环）的过程。你应该等几天（或一周），然后加入鱼，让自然细菌有时间生长。这些细菌会吃掉氨并将其转化为亚硝酸盐，而亚硝酸盐仍然有毒。在接下来的几周里，另一种细菌生长起来，将亚硝酸盐转化为硝酸盐，这几乎是无害的，并用作植物的肥料。这些细菌使水族馆更适合鱼类生存。简单了解这个过程对您的鱼非常重要。水箱在一个多月内完成循环。一种不正确的方法是在水质看起来不好时清空水箱。这样做会杀死所有细菌！然后你必须开始上面提到的所有过程，并再次进行氮循环。如果水箱开始生长藻类，买一条吃藻类的鱼，比如清道夫。无论如何，没有免费维护。几个月后，硝酸盐浓度开始增加，藻类大量繁殖和生长。解决这个问题的方法是每两周（或每周）更换一部分水。你可以用虹吸管清理砾石。你可以在任何宠物或鱼店买到它。该工具可以将砾石中的鱼的废物、未完成的食物和脏水吸入桶中，正确的水去除量为水箱体积的10%-25%。吸水后，用新鲜的无氯水填充水箱。确保你添加的水达到一定的温度，否则水箱的温度会迅速下降。这种方法可以去除水中的内源性氮，几乎可以保证鱼的健康和长期生长，但仍有一些事情需要小心。

如果鱼死了，一两周内不要购买新鱼。这可以让水箱本身得到调节，如果必要的话，可以滋生更多的细菌。如果你的水箱是5-20加仑（Fish3000注：1升=0.2642加仑），不要超过两三条鱼。大水箱，你可以立即放更多的鱼，但还是要小心。尽量坚持每加仑一英寸鱼的原则。有人说，这个原则仍然允许你的水箱超过它的容量，但始终保持这样的想法：不足总比过量好。

2。过滤器的功能

某些类型的过滤器旨在帮助细菌生长。这些过滤器通常被称为生物过滤器。最流行的两种类型是砾石下过滤器（UGF）和生物车轮过滤器。UGF使用上升的气泡或泵送使水流过砾石层。水首先通过砾石向下流动（向细菌提供氧气），然后通过沙子底部的滤板，最后向上流入提升管。我对这种过滤器有一种复杂的感觉。它们可以有效地为一些人工作，但它们可能充满垃圾和食物。如果你决定使用这个过滤装置，你应该经常清洗它，否则细菌会死亡，过滤器也会变得无用。生物轮滤器使用轮桨装置为细菌提供氧气。车轮放置在专门设计的动力过滤器的出口处。轮子有时在水中，有时在空中。只要轮子转动，细菌就会存活。一个非常精致的轮子应该是沉重的棕色。不要洗！否则，你将在几个月内再次杀死所有生长的细菌。一些过滤器不使用这些原理，但仍提供生物过滤。使用丝棉或海绵（过滤介质）的过滤器上滋生细菌。然而，这种方法效果较差。当它开始堵塞时，你必须彻底清洁或更换它，这也会去除细菌。海绵的额外好处是它可以重复使用，这将在未来为你节省一点钱。它们吸收硝酸盐和磷酸盐，否则它们将被藻类利用。无论如何，如果你不知道自己在做什么，植物会带来更多的问题。开始之前，请阅读更多有关植物的信息。植物的生长并不排除水交换的需要。事实上，植物需要水交换来提供对它们有益的微量元素。对植物来说，最大的问题是大多数物种需要大量的光照，是普通水族馆中动物数量的三倍多。定制带有多个灯光的封面是一种选择，但这可能不值得What are the ways to prevent goldfish from dying?

Goldfish (detailed introduction)

Goldfish is the most ornamental fish we breed. Although it is relatively good to breed, the mortality rate of goldfish is relatively high. There are many reasons for goldfish death. Over-saturated feeding without regular water change accounts for a large proportion. Now let's introduce the causes of goldfish death in detail to help you better cultivate goldfish

1、 Chlorine in your water

I don't know why not everyone knows this, but chlorine can kill fish in a few days. If you live in a town or have a water pipe instead of a well, your water will contain chlorine. Chlorine can kill dirty microorganisms and bacteria in drinking water, but it will also kill fish! The best way to avoid this problem is to put the water aside for a few days (let the chlorine volatilize), or buy a water purifier. The water purifier is cheap and easy to use. It only needs a few drops per gallon, but be sure to read the instructions before use

2、 Excessive feeding or lack of knowledge of nitrogen cycle

1. Precautions for aquarium

When fish are put into a new aquarium, their gills and waste will produce ammonia. Ammonia is toxic, just like chlorine, and will gradually increase after a few days. At this time, if you put all the fish in the aquarium immediately, ammonia will kill your fish quickly. So how do we remove ammonia? It passes through a process called nitrogen cycle (sometimes called ammonia cycle). You should wait a few days (or a week) and then add fish to give natural bacteria time to grow. These bacteria will eat ammonia and turn it into nitrite, which is still toxic. In the next few weeks, another kind of bacteria grew up and converted nitrite into nitrate, which was almost harmless and used as fertilizer for plants. These bacteria make the aquarium more suitable for the survival of fish. A simple understanding of this process is very important for your fish. The water tank completes its circulation in slightly more than one month. An incorrect way is to empty the water tank when the water quality looks bad. Doing so will kill all bacteria! Then you have to start all the processes mentioned above and carry out the nitrogen cycle again

If the water tank begins to grow algae, buy an algae-eating fish, such as a scavenger. Anyway, there is no free maintenance. After a few months, the concentration of nitrate began to increase, and algae multiplied and grew in large numbers. The solution to this problem is to replace part of the water every two weeks (or every week). You can use a siphon to clean the gravel. You can buy it in any pet or fish shop. This tool can suck the waste of fish in the gravel, unfinished food and dirty water into the bucket, and the correct removal amount of water is 10% - 25% of the tank volume. After you absorb water, fill the water tank with fresh, chlorine-free water. Make sure that the water you add reaches a certain temperature, otherwise the temperature of the water tank will drop quickly. This method can remove the endogenous nitrogen in the water and almost guarantee the health and long-term growth of fish, but there are still some things to be careful

If the fish is dead, do not buy new fish within a week or two. This can let the water tank itself be conditioned, and if necessary, more bacteria can grow. If your water tank is 5-20 gallons (Fish3000 note: 1 liter=0.2642 gallons), do not exceed two or three fish. Large water tank, you can put more fish immediately, but still be careful. Try to adhere to the principle of one inch of fish per gallon. Some people say that this principle still allows your water tank to exceed its capacity, but always keep the idea that insufficient is better than excessive

2. The function of filters

Some types of filters are designed to help bacteria grow. These filters are commonly referred to as biological filters. The two most popular types are UnderGravel Filters (UGF) and Bio-Wheelfilters. UGF uses rising bubbles or pumping to make water flow through the gravel bed. The water first flows down through the gravel (providing oxygen to bacteria), then through the filter plate at the bottom of the sand, and finally up into the riser. I have a complex feeling about this type of filter. They can work effectively for some people, but they can be full of garbage and food. If you decide to use this filter device, you should always clean it, otherwise the bacteria will die and the filter will become useless. The biological wheel filter uses a wheel paddle device to supply oxygen to the bacteria. The wheel is placed at the outlet of a specially designed power filter. The wheel is sometimes in the water and sometimes in the air. As long as the wheel is rotating, the bacteria will live. A very exquisite wheel should be heavy and brown. Do not wash! Otherwise, you will kill all the bacteria that grow up in a few months again. Some filters do not use these principles but still provide biological filtration. Filters using silk wool or sponge (filter media) have bacteria growing on them. However, this method is less effective. When it starts to block, you will have to thoroughly clean or replace it, which will also remove bacteria. The extra benefit of sponge is that it can be reused, which will save you a little money in the future

A more complex way to reduce nitrate is through plants. They absorb nitrate and phosphate, otherwise they will be used by algae. In any case, plants will bring more problems if you don't know what you are doing. Read more about plants before you start. The growth of plants does not exclude the need for water exchange. In fact, plants need water exchange to provide trace elements beneficial to them. The biggest problem for plants is that most species need a lot of light, more than three times the amount of animals in ordinary aquariums. Customizing a cover with several lights is an option, but it may not be worth the effort

Another advice is: If you have problems with a simple freshwater aquarium, don't buy a seawater tank! They take twice as much care as fresh water tanks, and cost at least twice as much as building and maintaining fresh water tanks. Unless you have a very firm attitude, or if you have too much money, it is probably not worth our trouble. Keep freshwater fish until you can keep them healthy for several years

Most tropical fish can live for at least one or two years, and the species with long life span can live for more than ten years. It seems that the life span of goldfish is not too short, so if you want to keep goldfish, you must pay attention to the above problems, so as to reduce the death rate of goldfish
