If the pH value of the fish tank is high, you can put some olive leaves, pineapple peels and sunken wood in the tank, and you can also use chemical reagents such as potassium dihydrogen phosphate, which can reduce the pH value and make the water acidic.It should be noted that after putting these things in, the pH of the water body should be checked regularly to see if it is necessary to continue to put them in.
1. Goldfish: Goldfish is one of the most common ornamental fish in China. It is mild in temperament, has a wide variety, and is very easy to raise.This kind of fish likes the weak alkalinity water quality, the water body Ph between 7.5-8 is quite good.As a eurythermal fish, it has a strong ability to adapt to temperature, but it is best to keep the breeding period at about 20 C.
2, guppy: guppy is a small tropical fish, suitable for survival in alkaline water, pH is usually between 7.2-7.4, but in neutral water can also raise a lot.Not only that, but many small tropical fish, such as moonfish and Mary fish, are suitable for alkaline water.
3. Sanhu cichlid: Sanhu cichlid is not a kind of fish, but a general term for cichlids living in the three Great Lakes of Africa. The three Great Lakes themselves have a relatively high pH, and the water body is alkaline, so this kind of fish should also be raised in weakly alkaline water.
