How to raise water in fish tank, how to adjust the pH value of water

New fish tanks need to be disinfected first. First, let the fish tank stand for a few days, then disinfect it with potassium permanganate solution, and then pour it out after 1-2 days with water. Then you can fill the tank with water, turn on the filtration system and the oxygen supply system, and adjust the temperature. Nitrifying bacteria are added into the water to culture a nitrification system. Finally, put some fish in the tank. After waiting for a week, if enter crock fish to do not have unusual, can release fish formally.

1. how to raise water in the fish tank

Before raising fish, you need to prepare the fish tank first. A newly bought fish tank cannot directly raise fish. It needs to go through the steps of raising water first. Specifically, water can be raised according to the following steps:

1. Disinfection and bubble tank: First, the new fish tank should be disinfected, because the fish tank may contain a lot of toxic substances. The empty tank can be left for a few days and then sterilized with a solution of potassium permanganate. After that, you can fill the fish tank with water, then soak it for 1-2 days, and then pour out the water, so that the toxic substances are basically eliminated. If you want to place stones, rockeries and other decorations in the fish tank, you also need to disinfect in advance.

2. Add water and adjust the temperature: After the fish tank is sterilized, you can add water. After filling the water, open the filter system and oxygen system to increase the oxygen content in the water. After doing this for about 2 days, the temperature can be adjusted, and the specific temperature can be seen in the requirements of fish.

3. Culture nitrifying bacteria: The next step is to add nitrifying bacteria to the water and culture the nitrification system, so that the ecological environment in the fish tank will be better.

4. Test: Before the formal fish culture, you can put some other fish, such as small goldfish, parrot fish and so on. You can use them to test whether the environment in the fish tank is suitable for the growth of fish.

5. Formal fish farming: After the test process is completed, we can formally put in the fish we want to raise.

2. how to adjust the pH of water

Generally speaking, fish have certain requirements for pH. Normal tap water is generally weakly alkaline. After a period of time, the fish will release carbon dioxide, which will reduce the PH value of the water, that is to say, they will become acidic. There are ways to make the water weakly alkaline. One of the more commonly used ways is to change water, because normal tap water is weakly alkaline. In addition, substances such as sodium bicarbonate can be put in to adjust the pH of water.
