What should I do if fish water turns into smelly water?

The water stinks because there are no nitrifying bacteria in the water, and whitening proves that the filtration function is not good. If the tank exceeds one meter, it must be equipped with multiple filter barrels. If you make your own fish tank, you can change the filter tank into three layers, the first layer of sponge, the second layer of biochemical cotton and the third layer of glass ring! After the improvement, change half of the water, put water purifier, nitrifying bacteria, water stabilizer, salt and dechlorination and sterilization water.

Because the water is not changed for a long time, or the filtration capacity is not enough, the nitrification system is destroyed and the water quality becomes worse. It is suggested to thoroughly disinfect and clean the filter material, increase the filtration capacity, add activated carbon, disinfect the fish tank and fish, change the water in the whole cylinder, change the water regularly in the future, and re-cultivate the nitrification system. In addition, getting a sweeper can help clean up the garbage.

If there is no water pump and filtration, the deterioration of water is obvious. Raising fish means that the pump keeps running. Only in this way can living water create a nitrifying bacterial community that can decompose garbage and harmful substances. It is necessary to simply configure the water pump and filter.
