Best Multifunctional Bottom Suction Pump - Best Manufacturers of 2022
The multi-function bottom suction pump is placed at the bottom of the tank, and the oxygen pumped out will disperse, and it will fill the water from the bottom up, absorb impurities, and filter the water body.

一.Why bottom suction pump is bottom suction?
Because the bottom suction pump used in the bottom filter tank can absorb the impurities in the tank and can absorb the residue of fish manure and fish food as well as the bottom residue, the water in the tank can be relatively clean, and the bottom suction function of the bottom suction
pump can indeed Suck the garbage away. These garbage are sucked into the fish tank, go through the filter cycle, and then return to the filter to filter your filter cotton. The bottom suction pump can suck feces 360 degrees, which is definitely larger than the bottom suction pump modified from the
side suction pump and the bottom suction kit, because the original design side suction pump has a pump seat, which will basically affect the water flow in one direction. Stool situation. It is like putting stones in a jar, and garbage will be collected under the stones.
二. Advantages and disadvantages of fish tank bottom suction pump
Lower filtration: There are many kinds. Most of the fish tanks use the height difference to make the water flow into the filter tank, then through the filter tank into several filter chambers at the bottom, and finally into the pump chamber, and the filtered water is pumped back into the tank through the pump.
Advantages: Several passing bins make the water filtration effect excellent. The filter material is easy to change and wash. It is also convenient to filter and change the water.
Disadvantages: poor water circulation. Bottom water cannot be filtered. If there is a blockage, it will cause overflow, and the consequences are more serious than filtering, and you may see an ocean when you get home.

三. Can the bottom suction pump of the fish tank suck fish manure?
Can
Because the bottom suction pump used in the bottom filter tank can absorb the impurities in the tank and can absorb the residue of fish manure and fish food as well as the bottom residue, the water in the tank can be relatively clean, and the bottom suction function of the bottom suction
pump can indeed Suck the garbage away. These garbage are sucked into the fish tank, go through the filter cycle, and then return to the filter to filter your filter cotton. The bottom suction pump can suck feces 360 degrees, which is definitely larger than the bottom suction pump modified from the
side suction pump and the bottom suction kit, because the original design side suction pump has a pump seat, which will basically affect the water flow in one direction. Stool situation. It is like putting stones in a jar, and garbage will be collected under the stones.
四. Solutions and causes of too loud water pump
Solution:
If the sound of the fish tank submersible pump is loud, there are generally two solutions. The first is to reduce resonance, which is due to its contact with some objects in the cylinder, which causes the sound to be amplified. In this case, just adjust the position. The second is to replace the submersible pump. Some pumps are of poor quality, so there will be a lot of noise. If you replace some variable frequency pumps, the sound will be much smaller.
reason:
1. Current sound: If the current of the motor is too loud, it will generate noise, which sounds like a humming sound. This situation cannot be solved personally, because it is a problem of internal structure, and easy modification may cause the submersible pump to be scrapped. It is recommended to replace it with a new one.
2. Shaft friction: When the submersible pump is working, the rotor of the water pump is lifted up by magnetic force, and at the same time the bottom is against the shaft, which can prevent the rotor from being hind legs due to water flow, but it will also generate a certain amount of friction, so it will make noise . Usually the life of the shaft is about one year, and it will be replaced after grinding.
3. Wheel friction: the friction unique to the turbo centrifugal pump, as long as it is this kind of pump, the noise cannot be avoided, but as long as the radian of the runner is well designed and the surface is relatively smooth, the volume of the noise can also be reduced.
五. How to maintain the bottom suction pump of the fish tank?
The water pump is the heart of an aquarium. In order to make this "heart" work properly, we must learn to maintain it. Otherwise, if the "heart" stops due to carelessness, it will be a disaster for the aquarium.
First of all, the water pump needs to be disassembled and cleaned regularly. There is a lot of filth in the aquarium, such as fish feces, rotten aquatic plants, and residual feed, which may be pumped into the pump. Due to the direction of internal rotation of the pump and the nature of impurities, a small part will remain in the pump, and impurities are most likely to be trapped between the turbine
chamber and the rotor stator. These dirty things will reduce the water flow of the pump, increase the working temperature, and increase the noise. Therefore, it is recommended to clean the water pump once a month, open the protective cover of the water pump, remove the turbine, rotor and central shaft, thoroughly clean the inside of the water pump, and use a waste toothbrush to clean the surface or dead corners. When cleaning, be sure to pay attention to the small internal parts, it will be troublesome if lost.
Secondly, the water pump cannot be installed too close to the sand, and the submersible pump cannot be used away from the water. Some people like to install the pump close to the bottom of the fish tank, thinking that the dirt will be completely pumped, but it is meaningless. As long as the pump is circulating, the dirt will be pumped into the filter along with the water flow. Installing the pump too low may suck the grit from the bottom of the aquarium into the pump, which can
seriously affect the life of the pump as it rotates. Also, do not let the water outlet of the pump face obstacles that are too close, and do not intentionally block the water outlet or half, these practices will shorten the service life of the pump.
Finally, pay attention to the wires and rubber suction cups of the pump. Rubber suction cups are low-quality consumables and should be replaced after about a year of use, otherwise it will not be able to fix the function of the water pump well. The wire used by the water pump is also very
important, because it is soaked in water half the time, even salt water, and prolonged soaking can make the wire stiff and even broken. In about 5-7 years, the wires of the water pump can be eliminated. Some fish with sharp teeth will bite the wires and cause short circuits. Freshwater fishes have such habits, such as toothfish, piranhas, large cichlids, etc., and seawater fishes have shells, angelfish and sharks. When raising these fish, wire To add a protective tube.
六.Is the low suction pump hard or hose connected?
Hard pipes for water pipes in fish tanks. (my personal usage)
The hard tube is straight, and it can be done horizontally, horizontally and vertically, which is more beautiful. Hoses reduce resonance problems.
How to hose water from a fish tank:
Long plumbing. One end of the length can reach the bottom of the aquarium, and one end can be connected to the water pipe at home. This length of water pipe is called long water pipe pumping. Usage: One end is connected in the tap water pipe, the other end is put into the aquarium water, then turn on the faucet switch, add water until the water pipe in the aquarium no longer bubbling but water comes out, that is, the air in the water pipe is emptied; at this time, the tap water is turned off, Pull out the water pipe and place it on the ground to pump water. Note: The height of the bottom of the aquarium should be higher than the height of the water outlet.
