? Generally, the newly opened fish tank does not need to put salt. Although the fish tank needs to be disinfected when the tank is opened, most of the medicines used are potassium permanganate, etc. Salt water disinfection has higher requirements for the amount of salt, and it takes a long time. However, it is often necessary to raise fish quickly when opening the tank, so salt is not suitable. In the later stage, there is basically no need to use salt, so as not to cause water quality changes.
of opening the jar? 1. Disinfection: The first step of opening the jar is disinfection. As mentioned above, potassium permanganate is usually used for disinfection. Fill the fish tank with water first, and then put potassium permanganate into it. The color of the solution should be darker, so that the disinfection effect is better. After soaking for 3-4 hours, drain and rinse several times.
2, raise water: Raise fish must raise water first, such fish ability are raised well. Usually the tap water can not be used immediately, it must be put in a sunny place for a few days, so that chlorine can be removed. After that, the water is injected into the fish tank, the filtration and oxygenation equipment is turned on to make the water clear and increase its dissolved oxygen, and finally the nitrification system is established, so it is necessary to pour in the culture material of nitrifying bacteria and turn off the light for a period of time.
3. Put the fish: After the water is raised, you can put the fish in the tank. At the beginning, you can put a few fish in the tank to test the water. If it is no problem to raise them for a week or two, then put other fish you want to raise. Fish in the tank must choose a more solid variety, so as to detect whether there is a problem with the water quality.
