Raise so many fish within a few days of opening the tank? It's a bit early to release the fish! Remember, the new tank must be watered first before putting the fish. The purpose of water cultivation is to remove chlorine in the water, and the other is to cultivate various microorganisms and bacteria that can purify water.
You have to know that a lot of toxic substances are produced in the Fish Tank every day. These toxic substances may be fish feces or spoiled food residues. Accumulation of these toxic substances to a certain level will poison the fish.
The microorganisms and various bacteria cultivated in water are responsible for removing and decomposing these toxic substances. These toxic substances are mainly ammonia and various organic substances that are turned into feces. Microbes and bacteria turn them into inorganic substances such as nitrates, which are very toxic.
The smell of your Fish Tank water is actually caused by the decomposition of fish feces into ammonia. Ammonia is a substance with a pungent and even odor, which is a great threat to the health of the fish. In the new tank you just opened, all kinds of beneficial microorganisms and bacteria have hardly been produced, so the fish feces and spoiled food residues will accumulate more and more, the water will become more and more smelly and the toxicity will become more and more serious.
It is recommended that you stop eating as soon as possible and stop feeding in the last few days. And change the water a lot to change the trapped water. Because the water is already smelly, you should change more, half the best. Changing the water can effectively reduce the concentration of ammonia nitrogen in the water and improve the water quality quickly. Then it needs to explode oxygen, because nitrifying bacteria and other microorganisms need oxygen to decompose the toxic ammonia nitrogen. Another explosive oxygen can also prevent the fish from hypoxia, enhance the fish's resistance, and prevent the fish from dying.
Finally, strengthen the filtering. Both physical filtration and biochemical filtration must be strengthened. Qualified physical filtration can intercept most particulate pollutants, that is, feces and residues. After all, qualified biochemical filtration is to cultivate a large number of beneficial microorganisms and bacteria, which can decompose the toxic ammonia nitrogen that has been dissolved in the water.
It's easy to say to strengthen physical filtration, just use good aquarium filter cotton to maximize the filtering function of filter cotton. Enhancing biochemical filtration requires adding a large amount of filter material, exploding oxygen, and waiting for a long time. After these two filters are done, the toxic substances in the water will be lower and lower, and the water will not be so smelly.
