Oxygenating the fish tank can keep it slightly acidic. This is because oxygenation equipment is to inject air into the water, and the air contains a certain amount of carbon dioxide, when it combines with water, it will become carbonic acid, which will make the water slightly acidic. Usually a few hours of oxygen every day can be, do not have to play all the time.
This is an almost pollution-free method to improve the acidity and alkalinity of water, but must be replaced in time, do not let it soak rotten. In addition to olive leaves, you can also use pineapple skin or sunken wood, but sunken wood will cause the color of the water to turn yellow, so it is best to deal with it before putting it into the fish tank.
Fish farming needs filtration. Some filter materials can play a role in acidifying the water body, such as soft water resin, volcanic stone, and so on. It should be noted that this adjustment method must be tested, otherwise it will easily lead to a sudden drop in pH, which will lead to the death of fish. Therefore, it is necessary to put in a small amount at different times, and then put in after measuring.
The method of drug regulation is similar to filtration, but this method also has certain disadvantages, that is, it must be put in regularly, otherwise the water quality will gradually change back. And if you often use drugs, it may also pose a threat to the fish in the water.
