In the front of the conclusion, there are five ways to solve the feces in the overflow area of the Sensen fish tank: 1. Install a miniature water pump in the overflow area, pump the feces into the sewer pipe, and finally intercept it on the filter cotton. 2. Place an aerotonite in the overflow area to beat the oxygen, and drive the flow of sewage in the overflow area through the rise of the air flow. 3. Install a siphon water pipe with a valve and discharge it through the regular switch of the valve. 4. If it is a decorative overflow plate, which is the so-called "false right angle overflow", the overflow plate can be removed. 5. Replace the complete set of triple overflow pipe fittings.
First of all, to analyze the problem, through the picture is not difficult to see, the baffle is the culprit, it forms a relative "three-dimensional still water area", the bottom water flow in the tank will blow the feces into the overflow area, the overflow area is very large, the water flow is dispersed, coupled with the high water level of the fish tank, the water flow has been unable to continue to blow the feces up. Over time, a lot of feces subsided.
The quality of garbage such as feces in the overflow area is very light, and it is only because the water flow is relatively slow that it will sink here, so as long as the water flow in the overflow area can be strengthened, the garbage such as feces can float up, and this problem will be solved. The methods are analyzed one by one as follows:

1. Micro water pump pumping
This method is the easiest to operate, just need to buy a miniature water pump to install at the bottom of the overflow area. The impeller of the pump will break the feces during the pumping process, and the outlet pipe of the pump can be connected to the sewer pipe of the fish tank. Sediments such as feces in the overflow area will pass through the sewer pipe to reach the filter cotton of the bottom filter.
The water pump can be opened for 2-3 hours a day or for a long time with the timer, and the specific use needs to be determined according to the actual situation. The water pipe of the pump is best to use a hard pipe, fix the position, and avoid unexpected conditions such as water jetting.
2. The gas head beats oxygen
It is necessary to have an air pump and an air stone that can adjust the gas volume, and the gas stone connected to the air pump is placed at the bottom of the overflow area, and the air flow injected by the oxygen pump allows the sediment such as feces in the overflow area to be driven by the upward air flow, and the probability that sediment such as feces can be brought to the sewer pipe by the water flow is increased.
This method may cause noise and affect the efficiency of the water surface oil removal membrane, so it is recommended to switch on and off at regular intervals every day.
3. Siphon water pipe with valve
Purchase the elbow water pipe shown in the figure, connect the hard water pipe at the end of the overflow area, and leave a distance of 1-2 cm from the bottom of the overflow area to facilitate the pipe to suck sewage in. This end-of-the-line water pipe with a valve leads straight to where it can be drained. You can do this once a week or once a day.
In order to avoid the drain pipe from slipping off, it is best to fix it with a suction cup, and only need to open and close the valve for discharge every day. This is the simplest siphon application. Siphon pipes can be purchased or made by themselves, depending on personal preference.
4. Remove the fake right angle overflow plate
Some of Sensen's fish tank styles are made of false right angle overflow, and the false right angle overflow plate makes the overflow area look more beautiful and avoids the fish hiding inside. Other than that, there is nothing else to do. Therefore, it can be directly dismantled, allowing the internal triple overflow pipe to circulate directly in the fish tank.
There are also people in the overflow area to put loach or some fish to stir the overflow area, easy to put, in case of death inside, found in time, want to take out a dead fish from the overflow area 60 cm deep, very laborious.
5. Replace the complete set of overflow pipe fittings
This method is a little troublesome, that is, it needs to be cleared, but it is basically a solution to the problem once and for all. After completely removing the overflow area of the fish tank, buy a triple overflow pipe fitting of the same caliber in a treasure and install it directly. Because the diameter is the same, there is no need to punch holes again, so the installation is not complicated.
The above scheme needs to be used according to the actual situation of the fish tank, each scheme has its own advantages and disadvantages, the use of the process must be careful, the fish tank is filled with water glass, any rude operation may cause accidents.
