fish tank is to change the water regularly. Changing water is an essential step in the process of fish farming, which can improve water quality, reduce the content of harmful substances in water, and also has a good effect on the removal of fishy smell. It should be noted that water should not be changed too frequently, otherwise it will pose a threat to the health of fish.
has a fishy smell is that the ammonia nitrogen content in water is relatively high, and the best way to remove ammonia nitrogen is biological filtration, that is, to cultivate nitrifying bacteria. Nitrifying bacteria can convert ammonia nitrogen into nitrate, thus avoiding poisoning fish. It should be noted that the filter material should not be cleaned frequently, otherwise the nitrification system will be destroyed.
water is due to the decomposition of organic matter, and the source of organic matter is fish food. Usually feeding must control the amount of food, can not feed too much, each feeding should be finished in about 3-5 minutes. In addition, if there is too much residual bait in the water, it is better to clean it up and suck it away when changing the water.
if there are dead fish in the fish tank, it will also produce a fishy smell. In view of this situation, it is necessary to fish out the dead fish in time and disinfect them properly to prevent other fish from dying. If the dead fish are too frequent, the situation will be more serious, and the situation must be improved by turning over the tank.
