Homemade fish tank filtration system

How to make a homemade fish tank filter (preferably with pictures)

To make a homemade fish tank filter, you can follow the following steps: 1. Determine the filtration mode according to the breeding objects.

For example, if you want to raise small tropical fish in a grass tank, you can use a barrel filter; if you want to raise coral saltwater fish, it is best to use a bottom filter. 2. Design the filter tank specifications based on the determined filtration mode, fish tank size, etc.

3. Determine the filtration flow rate (water pump power) based on the determined filtration mode, fish tank size, filter tank specifications and other parameters. 4. Draw design drawings based on the relevant parameters determined above.

5. Purchase and produce main materials, auxiliary materials and tools according to the design drawings. 6. Assemble the main materials and auxiliary materials using tools and design drawings.

7. Actual water release and debugging. 8. Officially put in the filter material and start using it.

In addition, since the filtration modes are divided into dozens of modes such as upper filtration, side filtration, back filtration, bottom filtration, barrel filtration, and inner filtration, it is impossible to illustrate them one by one. Give a bottom filter as a reference.

How to make a simple filter for your fish tank?

1. First, add a few small holes on the mouth of the pulsating bottle to increase the water flow and prevent the water from overflowing when the water output is small. Of course, if your water pump power is relatively small, it is okay not to drill holes.

2. Then, cut off the bottom of the bottle.

3. Then the prototype will come out, and the next step is simple. Just insert the filter material layer by layer. Remember to put the bottle mouth down. The one in the tank at the back was made by the original poster for the first time.

4. As for what filter material to put and how to put it, it depends on your preference. I put nitrifying bacteria balls, filter cotton, and nitrifying bacteria rings. It is relatively simple. The main bottle is not big. It doesn’t contain too many things. After all, it is placed at the water outlet of the upper filter box and is filtered twice. The water flowing through it is equivalent to a coarse filter.

5. Then enter the water.

The details are as follows:

1. Filtration methods The main filtration methods include: physical filtration, biological filtration, chemical filtration, etc.

2. Filter Forms There are many types of filters, such as: gas-lift biochemical cotton filters, barrel-type external filters, aquarium top filters, shaped fish tank filters, etc. .

3. Characteristics of the filter

1. The gas-lift biochemical cotton filter sucks the biochemical cotton to the bottom and connects it to an air pump or water pump, and relies on the flow of gas in the water to drive the water flow. Internal circulation of biochemical cotton. Organic substances such as residual bait and biological excrement in the water can be adsorbed on the surface of the sponge.

Advantages of gas lift biochemical cotton filter: simple structure, low unit price, and can be directly put into the fish tank water for use.

Disadvantages: The filtration principle is simple and the effect is poor. The biochemical cotton needs to be cleaned frequently and it will affect the viewing when placed in the fish tank. It is suitable for excessive use in small fish tanks during the breeding period and isolation treatment period, but it has little effect when the water quality is too dirty.

2. Barrel-type external filter is generally a closed barrel-type filter placed outside the fish tank container. Different filter materials can be placed according to different needs to achieve different filtration effects.

Advantages of the barrel-type external filter: it does not take up space, is beautiful, has low noise, can be placed in more filter villages, and has good filtration effect.

Disadvantages: Troublesome to clean, relatively expensive, only suitable for use in larger fish tanks.

3. The top filter of the aquarium is a filtering device placed on the top of the aquarium. A small water pump is used to pump the water in the aquarium into the filter box where the filter layer is placed. The water flows through the filter layer and then back into the aquarium, thereby removing impurities contained in the water and purifying the water quality.

Advantages of the filter on the top of the aquarium: it can make full use of the space on the top of the aquarium, and it is convenient for daily maintenance and cleaning.

Disadvantages: Placing a filter device on the top of the fish tank affects viewing from top to bottom and is not suitable for raising back-viewing fish.

4. The fish tank filter with a shape adopts a multi-functional filter device with emerging technologies such as invisible filtration device and ecological-like principle. The internal use of ecological-like filtration principle is comprehensive, and the external design has a beautiful shape that can be decorated. Fish tank, placed directly on the bottom of the fish tank for use.

Advantages of the fish tank filter with a shape: beautiful appearance, in addition to filtering and oxygenating, it can also decorate the fish tank, does not affect the viewing, uses the ecological filtration principle, has good filtration effect, and can extend the water change time to the maximum time; It is easy to use and placed directly on the bottom of the fish tank.

Introduction to homemade fish tank filters

Only with a good filtration device in the fish tank can you raise good fish and change less water.

1. Filtration methods Filtration methods mainly include: physical filtration, biological filtration, chemical filtration, etc. 2. Filter forms There are many types of filters, such as: gas-lift biochemical cotton filters, barrel-type external filters, aquarium top filters, shaped fish tank filters, etc.

3. Features of the filter 1. Gas-lift biochemical cotton filter. Suction the biochemical cotton to the bottom and connect it to an air pump or water pump. The flow of gas in the water drives the water flow to circulate in the biochemical cotton.

The volume is not easily too large and is not suitable for large fish tanks. 4. Principle of filter The filter must have two or more filtration methods: physical filtration, biochemical filtration, and chemical filtration. Physical filtration: It uses mechanical methods to separate larger particles from the water.

For example, remaining feed pellets, dead fish bones, fish excrement, secretions, vomitus, body surface mucus, etc., generally use sponges, spray cotton, and fine-mesh nylon nets. , palm leaf fiber, etc. It is usually set at the initial end of the filtration system for easy cleaning.

Biological filtration: Cultivate beneficial bacteria, and use bacteria to decompose harmful elements, such as ammonia, nitrite, nitrate, phosphate, etc.

Commonly used filter materials include: biochemical balls, ceramic rings, glass rings, coral sand, etc. (the most important filtration method, maintaining the ecosystem) Chemical filtration: It is a method of using chemical agents to remove impurities from water. The agents used are: Water quality stabilizer, flocculant, algaecide, protein decomposer, deodorant, etc. Adsorption filtration: It is wood, coal, fruit shells, animal bones and other substances with extremely high carbon content that can absorb proteins and trace amounts in seawater. Elements, decolorization, odor removal, and even ozone molecules can be absorbed by it.

Fish urine, microalgae and drugs in the water can also be adsorbed by it. Because nitrifying bacteria must live in the filter cotton, glass ring or bottom sand of flowing water, the filter should Open 24 hours. Classification by filtration principle 1. Self-cleaning filter A self-cleaning filter uses a filter to directly intercept impurities in the water, remove suspended solids and particulate matter in the water, reduce turbidity, purify water quality, and reduce system dirt, bacteria, algae, rust, etc. , a precision device used to purify water quality and protect the normal operation of other equipment in the system.

The main components of the self-cleaning filter include: motor, electric control box, control pipeline, main pipe assembly, filter element assembly, 316L stainless steel brush, frame assembly, drive shaft, inlet and outlet connecting flange, etc. The self-cleaning filter overcomes the many shortcomings of traditional filtration products such as small dirt holding capacity, easy to be blocked by dirt, the filter part needs to be disassembled and cleaned, and the filter status cannot be monitored. It has the function of filtering raw water and automatically cleaning and draining the filter element.

The system provides uninterrupted water supply during cleaning and discharge of the self-cleaning filter. It can monitor the working status of the filter and has a high degree of automation. Covering various filtering precision requirements from 10um to 3000um.

The self-cleaning filter adopts advanced equipment technology in the international water treatment industry and can be installed vertically, horizontally, or inverted in any direction and in any position. It can be used in industry, agriculture, municipal power, electronics, medicine, food, printing and dyeing , construction, steel, metallurgy, papermaking and other industries water filtration. 2. Fully automatic filter Fully automatic filter is a set of equipment widely used in the filtration industry. It overcomes the many shortcomings of traditional filtration products such as small dirt holding capacity, easy to be blocked by dirt, the filter part needs to be disassembled and cleaned, and the status of the filter cannot be monitored. , with the function of filtering raw water and automatically cleaning and discharging the filter element.

The fully automatic filter consists of a housing, a multi-element filter element, a backwash mechanism, an electric control box, a reducer, an electric valve and a differential pressure controller. The diaphragm in the housing divides the inner cavity into upper and lower chambers. The upper chamber is equipped with multiple filter elements, which fully utilizes the filter space and significantly reduces the filter volume. A backwash suction cup is installed in the lower chamber. .

When the fully automatic filter is working, the turbid liquid enters the lower chamber of the filter through the inlet, and then enters the inner chamber of the filter element through the partition hole. Impurities larger than the gap in the filter element are intercepted, and the clean liquid passes through the gap to reach the filter element. upper chamber, and finally sent out from the exit. The default precision of the fully automatic filtration is 10 microns, and it is optional from 100 to 3000 microns. It has a large filtration area and high dirt holding capacity. Users can customize it according to actual working conditions.

The cleaning method is simple, and the cleaning cycle is electronically monitored, which can realize automatic cleaning and sewage discharge. All parameters in the fully automatic self-cleaning filter control system can be adjusted.

3. Stainless steel brush filter Stainless steel brush filter types include: fully automatic stainless steel brush filter, hand-operated stainless steel brush filter. Its main function.

Picture of how to make a homemade fish tank filter

Making a homemade fish tank filter is very simple. First, you need to go to the mall or supermarket to buy a relatively large piece of cotton cloth, preferably It is relatively heavy, because the filtering function of that kind of cloth is very good, and buying a larger plastic plate, these two things are indispensable.

In the first step, use a tool to cut the plastic plate into 4 small rectangles with the same width and length; then cut 2 squares with the same width as the rectangle, and then cut one of the squares and the rectangular plastic block Drill a hole as large as the diameter of the fish tank water pipe, then use a rectangular plastic block at the bottom, and use waterproof tape to fix them into a box. Remember not to seal the top cover so that you can replace the filter later.

In the second step, use scissors to cut the cotton cloth into a rectangular-sized filter. Take one of the blocks and put it into the prepared box, insert the filter tube of the fish tank through the square hole, and close the lid.

Your homemade fish tank filter is complete. In the future, if the filter becomes dirty, just replace it with a cotton cloth of the same size.

How to make a fish tank filtration system

Suggestions: 1. Use a 35W bottom filter, if you are a fish farming enthusiast, or plan to raise rare and expensive fish species for a long time.

2. Use a 35W filter barrel and a pre-filter box, so that only the pre-filter box is cleaned, and the filter barrel cultivates nitrifying bacteria, which is suitable for precious fish species.

3. If you raise peacocks and red arrows, cut no more than 30 peacocks, use a 15W ordinary filter box, and put a 2KG-4KG nylon mesh with a porcelain ring in the fish tank to stabilize the water quality and the nitrifying bacteria carrier. This solution saves electricity and is practical. (I have a 1.2-inch fish tank with this plan, which is used to breed peacocks.) It is necessary to regularly remove the excrement from the bottom of the water and change the water in small amounts. The 15W water pump can only play a role in flowing water and filtering, but cannot completely suck away the low-level excrement in the tank.

The above is my personal opinion on long-term fish farming and is not universally representative. It is for reference only. As for other fish farming enthusiasts, they can publish their own introductions. I will not participate in the debate.

How to make your own small fish tank filter

Homemade small fish tank filter: 15W water pump, flow rate is 800L per hour, so if you use a 1L pulsating bottle, a 600ML one will overflow.

1. Now put a few small holes on the pulsating bottle mouth to increase the water flow and prevent the water from overflowing. Of course, if your water pump power is relatively small, it is okay not to drill holes. 2. Cut off the bottom of the bottle.

3. The prototype has come out, and the next step is simple. Just insert the filter material layer by layer. Remember to put the bottle mouth down. The one in the tank at the back was made by the original poster for the first time.

4. As for what filter material to put and how to put it, it depends on your preference. I put nitrifying bacteria balls, filter cotton, and nitrifying bacteria rings. It is relatively simple. The main bottle is not big. It doesn’t contain too many things. After all, it is placed at the water outlet of the upper filter box and is filtered twice. The water flowing through it is equivalent to a coarse filter. 5. Get into the water.

6. Try it to see if there is overflow. If the flow is not too large and there is no overflow, it is OK. It is very simple, but very practical. With the original upper filter box, the effect is quite good and the cost is very low. .
