1. the reason why the feces of

fish sink to the bottom is mainly due to the limitation of water flow. The feces can not follow them into the filter tank, so they will accumulate more and more at the bottom of the tank, which greatly affects the ornamental value. There are two ways to enhance filtration, one is to increase the power of the pump, which can speed up the flow of water, so as to better wash away the feces. The other is to establish a nitrification system. Although nitrifying bacteria can not directly help to clean up the feces, it can convert the ammonia nitrogen produced by the decomposition of feces into nitrate to avoid poisoning fish.

In addition to cleaning the feces at the bottom of the fish tank by filtering, it can also be cleaned when the water is changed. Prepare a hose, put it to the bottom of the fish tank, the other end should be lowered, through the siphon method to suck out the water at the bottom of the tank, so that the feces can also be brought out. Of course, after pumping out the old water, new water should be added from the wall of the jar. If you change water in this way at ordinary times, you will naturally not feel troublesome, but it may be difficult if you haven't used it.

If you just want to clean the feces at the bottom of the tank in a short time, it is also a good choice to raise clean fish. Generally, scavengers are used, which can suck away the dirt at the bottom of the water, so as to make the tank look cleaner and tidier. It should be noted that clean fish is not only eaten without pulling, once excreted, the situation will be the same as before, so this method can not cure the symptoms.
