How big pump is used for a 1 meter fish tank, how big pump is used for 1 2 meter fish tank

The pump power required for a one-meter fish tank is usually between 20W and 55W, depending on the total amount of water in the tank, the type of fish raised and the filtration.

If the width and height of the fish tank are limited, and only goldfish are raised, a 20W water pump is sufficient. If you have a large tank space and are raising marine fish, then you may need a 55W pump. It is necessary to ensure that the water in the tank can be filtered about 7-10 times per hour.

Specifically, what kind of water pump to choose needs to be purchased in combination with the actual situation of the fish tank at home.

The length of the fish tank is only a parameter for selecting the pump, and this data alone is not enough to judge what pump is more suitable. Let's take a simple example. The same one-meter tank, one is a meter long, 30 cm wide, 50 cm high tank for goldfish, and a 20w three-in-one submersible pump with upper filtration is enough.

A one-meter long, 60 cm wide, 60 cm high, plus 80*40*40 bottom filter tank to raise marine fish, 55w feels small.

Therefore, the choice of water pump can not only look at the length of the fish tank, but also look at the following factors:

1. Overall water volume.

2. Breeding species.

3. Filtration type.

Let's say your fish tank is 100 cm long x 45 cm wide x 50 cm high.

It is recommended to use a filter flow rate of 675 1125 [l h] liter hours.

Suitable for 12W submersible pumps.

The fish tank uses a water pump of about 20 watts, and the volume of the fish tank is not large, so there is no need to choose a large water pump.

The principle of pump power selection is usually to achieve an hourly flow rate of 2-12 times the total amount of water. Stones and other decorations should be padded under the fish tank, that is, there should be a void layer below to allow the water to flow.

It is not a good thing that the water is filtered quickly, the chemical bacteria are added to the filter cotton (biochemical cotton) and the glass ring, and the stabilized water can enter the tank together when the water is changed, and the filtering bacteria must be turned off the light operation, because the bacteria are afraid of light, which will affect its reproduction.

The following is for reference.

The water capacity of the rice fish tank is about 360 liters of water.

It is recommended to use a water pump with a flow rate of 1800 l h.

It's about a 30w water pump.

Or a water pump with a frequency conversion of 11W.

Let's say your fish tank is 120 cm long x 45 cm wide x 60 cm high and your fish tank has a capacity of about 324 litres of water.

It is recommended to use a submersible pump with a flow rate of 972-1620l h (liter hour), and a submersible pump of about 8-10 watts is more suitable.

If you want to have a good filtration effect and the conditions are okay, it is recommended to use an off-tank biochemical filtration pump.

Conditions: 1. The cylinder can be hung on the outlet pipe, and some cylinders can not be hung.

2. Economic conditions permit.

**About 200 yuan. Excellent filtration!When buying this kind of filter, pay attention to ask the salesperson to put everything in the filter barrel, so that you don't have to put it when you go home.

Then you can use the kind of filter pump on the filter box, which is cheap, and you can use about 40w, about 30-40 yuan. This filter has a mediocre filtration effect. There are not too many precautions to buy this filter, you just need to let the merchant try whether it is easy to use, and then listen to whether the noise is very small.

The length of the fish tank is only a parameter for selecting a water slag pump, and this data alone is not enough to judge what pump is more matched. Let's take a simple example. The same one-meter tank, one is a one-meter long, 30 cm wide, 50 cm high tank to raise goldfish, and a 20w three-in-one submersible pump with upper filtration is enough.

A one-meter long, 60 cm wide, 60 cm high, plus Wang Xian's 80*40*40 bottom filter tank to raise marine fish, 55w feels small.

Therefore, the choice of water pump can not only look at the length of the fish tank, but also look at the following factors:

1. Overall water volume.

2. Breeding species.

3. Filtration type.
