The food residue left in the tank will be broken or pulverized, which will cause the water in the fish tank to be turbid, and the filtering burden will increase after passing through the filtering system.
If your filtration system is ineffective, it will soon lead to water quality deterioration and fish death.
The landlord likes to raise fish, but you can pay attention to our company's latest patented fish tank, which is known as the strongest fish artifact in history. This is not bragging, but based on facts. Look at the size of this water tank Koi fish 1 fish with a height of more than 30 cm, 3 koi fish fish with a height of more than 10 cm and 2 goldfish. These fish have been raised for half a year, and they have only changed water and washed cotton once. Looking at the pile of high fish excrement behind the filter, a sense of accomplishment arises spontaneously.
You should probably understand why water can be kept so well and fish can be kept for so long.
