1, the owners of early fish farming don't have to care too much about the data of water quality. Such as PH value, KH value and so on. Except, of course, seven colors. I once read a book of British aquarium lovers, which introduced in detail the water quality data needed for raising tropical fish. But at the end of the book, there is such a sentence that is impressive. Some data about water quality, such as PH value, KH value, etc. Most of them are confined to large-scale tropical fish farms, so it is unnecessary to bother to pursue some water quality data to raise tropical fish at home. Having said that, it should be noted that the owner can also measure whether the water data meets the suitable indicators for the fish he wants to raise, but he thinks it is not necessary for the owner who originally raised fish.
It is a cliche to raise fish first and then water. Why do you always bring it up? This shows the importance of saving water. Owners of early fish farming must remember to be patient when raising water. You know, to some extent, raising fish is to see if the owner has patience! When raising water, be sure to keep the filter open for 24 hours (if the filter is not opened, the water will deteriorate after a long time), and the temperature should be raised to 30 degrees, and this state should last at least 10 to 15 days (the more days, the better). If the water temperature is kept at 30 degrees during hydroponics (note: some nitrifying bacteria can be added appropriately, and it is best not to add some chemicals), this water is not old water, but at least it can be said to be cooked water. Then buy some cheap fish and put them in. After a week, the survival rate of fish is high, and the owner can eat new fish.
When buying fish, how to choose healthy fish is extremely important. Here, I will introduce two simple and effective methods to you. 1: Tap the tank wall with your hand, which fish is sensitive and which fish is basically healthy. 2. Generally, fish like to swim in groups. It is basically healthy to find which fish leads the swimming in front. When buying fish, try to buy it in the aquarium to avoid cross-infection of bacteria carried by fish to some extent.
4. Feeding density. Don't buy all your favorite fish back. You should know that one centimeter of water raises one centimeter of fish. Moreover, some fish are not suitable for mixed culture. From the aesthetic point of view, there are too many kinds of fish in the tank, and it is also very chaotic. We must pay attention to the distinction between primary and secondary.
5. Changing water frequently at ordinary times helps to maintain good water quality. However, the frequency of changing water is too frequent, which has certain influence on the external mucosa and nitrifying bacteria of fish. Therefore, on the issue of changing water, it is sometimes contradictory. So how can we solve this contradiction? This undoubtedly depends on a powerful filtration system to ensure the observation of water quality in peacetime. The power of the filter should be 3 to 5 times per hour to filter the total water in the cylinder. The collocation of filter materials depends on the situation. Owners of early fish farming generally don't need to spend too much time on ceramic rings and activated carbon. They just spread a layer of biochemical cotton on the bottom of the filter tank and two layers of filter cotton on it. Note: activated carbon and ceramic rings have never been used, but the water is clear and the fish are happy.
6. Many owners like to use salt in the process of raising tropical fish. But combined with the experience of fish farming, I want to say a few words about salt. Owners of early fish farmers should remember not to use salt in their lives. Salt contains iodine, which is fatal to fish. The big salt sold in the market is not very pure, so seawater salt is recommended here. Occasionally (not necessarily or often), you can sprinkle the right amount of salt into the tank. Salt can effectively prevent water mold, and at the same time, it is rich in trace elements, which can also improve the appetite of fish.
7. When the fish is sick, don't just put medicine into the jar without knowing what the disease is. Try not to filter and isolate as much as possible, but be sure to add oxygen.
8. It is very important to pour water into the newly bought fish. Fish are extremely sensitive to changes in temperature and water quality. Therefore, it is essential to pass water and pour water. On the issue of quarantine, I think the most important thing is to see the source of the owner's fish and whether it was bought in the aquarium. This can be decided by yourself. Here, an extremely simple indigenous method to quarantine fish, to be precise, should be disinfection. If you buy fish from the familiar JS, you will generally not go through quarantine procedures. The usual method is to add a proper amount of methyl blue and salt to the plastic bag when buying new fish and pouring water. Soak for about 30 minutes, then pour water until the blue color in the water gradually disappears.
When raising ornamental fish, we need to pay attention to this problem of feeding density.
