Can ? Yogurt can make the water in the fish tank clear. The reason for this effect is that yogurt contains bacilli and cocci, which can skip the process of acidification and decay and directly produce hydrogen and methane. Although this can make the water clear, it is not suitable for the survival of fish, so it is better not to pour yogurt into the tank, otherwise it will cause a large number of fish to die.
1. Filtration: If you want to make water clear, you must first pay attention to filtration. Filtration is generally divided into two types, one is physical filtration, and the other is biological filtration. Physical filtration can suck the particles in the water into the filter tank to ensure the clarity of the water body, while biological filtration can convert the ammonia nitrogen produced by the decomposition of organic matter to avoid poisoning the fish.
2. Change the water: If you want to improve the water quality as soon as possible, changing the water is a very good way, but you must control the amount of water, otherwise, although the water is clear, the beneficial bacteria will be eliminated, and the water will not keep the fish alive. So once a week is the limit, and you can't change more often.
3, administer medicine: The so-called administer medicine is not to use some kind of medicine to cure a disease, but to use alum. This substance can react chemically in the water, thus adsorbing suspended particles in the water, and finally turning into a white flocculent precipitate. When the impurities in the water sink to the bottom, the water will naturally become clear.
