How deep does it take to build a fish pond, and how to solve the filtration problem?

If you are in the north, it is better to do it deeper, so it is too cold in winter, if you don't do it deeper, the fish may die of cold, and in the south, it is okay to be a little shallower, generally, if it depends on how deep you want to do it. If you filter, it is better to do the filter tank, and put brushes, coral stones, and biochemical cotton biochemical balls in the filter tank, which is easy to take care of, but it takes up more space.

If you raise goldfish, you don't need to be too high fifty or sixty centimeters, the water depth of fish farming is about 30, the water level can be raised in hot or cold weather, if you don't need a filter device for building a cement pool, you can completely change the water once in about 15 days, and there will be no lack of oxygen. If you raise koi, you need to build a pond about a meter deep.

The depth of the fish pond construction Many aquarists who raise koi fish for the first time are reluctant to build the koi pond too deep, basically starting from 40-80cm, but with the continuous improvement of the level of breeding and appreciation, it is time to toss. Because the depth of the water determines many factors, such as: wintering problems, growth, size, number of farms, etc.

Old aquarists know that a large body of water can provide a better growth space for any fish, and the depth of the koi water also has a certain impact on the size of the fish. Built on not. You can come and ask about the water purification of the fish pond.

Try to be as deep as possible, so that you can't dry the fish in the summer, and you can't freeze the fish in the winter.

1. Generally speaking, a simple filtration system is installed in a private fish pond or fish tank to effectively prolong the deterioration time of the pool water. For example, ornamental fish ponds. The previous fishpond filtration system was too complex. It occupies a large area, and the filtration effect is not very good.

2. At present, the simplest fish pond filtration system is composed of fish pond sand filter tank, filter material, pipeline and water pump. It's simple. The sand filter tank will be filled with various fish pond water quality filtration materials to intercept the dirt and make the filtered water flow back to the fish pond.

This is a new fishpond filtration system. If the water quality is turbid, the water purifier can be combined with recycling to maintain the water quality for a long time.

3. Another way to maintain the water quality of the fish pond is to use the fish pond water purification stone, also known as the microbial water purification stone, which is produced from porous concrete and sealed with alkaline BB bacteria. BB bacteria can survive quickly, grow and reproduce, effectively decompose organic matter such as fish feces and fish food residues in the water, reduce the ammonia nitrogen content in the water, effectively prevent the deterioration of water quality, and inhibit the growth of algae. Microbial water purification stone forms a microbial system, which maintains the self-purification ability of the water body for a long time, is efficient and environmentally friendly, and will not cause harm to fish.

4. In many people's minds, filtration is to remove suspended solids from the water and make the water clear, but this is not the case. The real circulating filtration system can not only remove suspended solids and excess algae in the water, but also decompose the substances harmful to fish in the water by decomposing beneficial biochemical bacteria such as ammonia nitrogen and nitrite, and convert them into substances that are harmless to fish, so as to maintain the stability and quality of water quality for a long time.

To sum up, for the installation of a simple filtration and circulation system, only one water pump + filter sand box + water pipe is required. If there is a fish tank for fish farming, the method is the same. However, the device is simpler.

It is also necessary to let the water flow. You can buy a small circulating water pump or an oxygen merchant.

Put all kinds of filterable materials in the fish pond and plug them in so that the filter material can be turned and the filtration system can be started.

The filtration system of the fish pond should be divided into three layers, you can put some fine sand underneath, or you can put some larger stones, and then inject water into the fish pond to form a good filtration system.

Prepare the fish pond sand filter tank, filter material, pipeline and water pump, the fish pond sand filter tank will filter the water of the fish pond, and then return to the fish pond again through the action of the pipe and water pump to form a recycling mode.

a, Physical filtration: generally using rotary drum filter, its main characteristics are low energy consumption, large circulating flow, fully automatic. The main purpose is to remove leaves, suspended solids (skimmers) from the water, and to remove sediments such as fish feces and silt from the bottom (bottom filter at the bottom of the pond).

b, Biochemical filtration: The purpose of biochemistry is to reduce the content of dissolved organic matter in water, so as to prevent water deterioration and odor, prevent water eutrophication, and cut off the nutrient source of algae outbreaks. Biochemical filter materials are generally divided into sponges, elastic brushes, stool edges, etc.

The material is mainly considered from the surface area, in which the specific surface area of the sponge is large, and it can also adsorb some fine particles in the water. c, sterilization and disinfection: the purpose is to kill some harmful bacteria, viruses, and algae in the water.

From the perspective of technological process, the three processes of physical filtration, biochemical filtration, sterilization and disinfection can fully meet the needs of koi fish ponds.

The main purpose of filtration is early use or biochemical filtration. Requires long-term uninterrupted use. In this way, it can not only filter out the suspended solids in the water to make the water clear, but also improve the water quality, degrade harmful substances, and ensure the health of the fish.

Establishing an effective biochemical filtration system can greatly reduce the need for water exchange. If you just need to suck up the dust from the pool, go to the hardware store and buy a 100-watt sump pump. Make a hole under the turnover box and fill it with filter cotton.

The water is pumped with sewage and then flows back to the fish pond after passing through the branch leakage turnover box, and it is quickly clean.

First of all, there are two types of needs and needs.

The ancient method of fish farming is the ancient method that has been passed down to modern times, without aeration and filtration. In order to make the pool water or tank water grow green, the moss will be used to wipe the walls of the tank and the bottom of the tank with starch vegetables such as taro. Then it was waterproof for a few days and it was covered with green moss.

Under photosynthesis, the green moss is oxygenated. Filtration also relies on green moss, which will attach nitrifying bacteria to biodecompose toxic substances. As for manure, etc., directly plant aquatic plants such as bowl lotus for plants to absorb, and use manure as base fertilizer.

It can be said that the ancient cultivation method is very energy-saving and ecological. The ancient method of raising fish generally does not exceed 30cm in water, so that the plants will get good light to produce oxygen, and the fish also change color very well because of the light.

There is a modern method of filtration, in fact, one is convenient, one is for some species, now many varieties are hybrid, to a very high flow rate of water flow, and complete filtration of water has a certain depth, such as goldfish in the Thai lion, etc., these new fish species are more than 1 meter deep.

Your pool is about 10,000 litres of water. Therefore, the water pump should be at least 20 tons of water per hour. It doesn't matter if you filter the tank, because as long as you have a large amount of water, you can filter a fish tank that is larger than the fish tank itself for bottom filtration.

But it's impossible for you to make your pool that big. Actually, it still depends on the nitrifying bacteria in your pool. And the cost of these is very high, and a thousand yuan can't be beaten.

In fact, I suggest that there is no need to engage in filtration, it is good to raise fish in the ancient way, and spend a maximum of dozens of yuan to buy 2 solar fountains that can float on the surface of the water and throw them into the pool to increase oxygen and disturb the water flow. Anyway, if it's solar, you don't need home electricity. It's okay to throw some lotus seeds into the water, or wait for the horseshoe to dig the horse's hooves to eat.

It is best to do old-fashioned filtration to 4 squares, which is the minimum, so the effect is not very good, so it is recommended to use a filter, the real drip area is small, the effect is good, and it is convenient to clean.

Didn't use a filtration system, did you? After all, the fish pond is a pool of stagnant water and needs to be recycled, otherwise it will easily deteriorate after a long time. Of course, you can use fish pond water purification equipment to keep the water circulating, and now a new type of koi fish pond filtration system is becoming popular on the market, which consists of a fish pond filter, a water pump, and a pipe filtration system.

It is recommended to use the Pimp fish pond to purify the water, and the effect.

General family view.

If you want to use it, you can use the filter directly, and the professional farm can filter with a traditional pipe, depending on how big the pool you are, the filtration is not the same.

Depending on the size and shape of the fish pond and the amount of water to build the filter pond, an all-in-one filtration system can also be chosen. The filter pool occupies a large area, and the effect is very good, but it is troublesome to clean. The all-in-one filtration machine occupies a small area, does not need to be manually cleaned, and the effect is also good.

The proportion of the filter tank is not less than 20% of the total water body, and the water depth is recommended to be not less than meters.

There are two types of filtration: overflow and trickle. If you are really in the courtyard, it is best not to set up a drip, because it will be noisy and affect the rest. Overflow filtration is the foundation, and the overflow filtration part can be divided into precipitation, physics, biochemistry, and clean water.

The bottom pipe of the main pool is connected to the filtration and sedimentation bin, through the anti-water plate to the physical filtration and biochemical filtration part, and finally to the clear water warehouse, and the water pump is pumped back to the main pool. To set up the face water pipe, the 90-degree pipe fittings are passed into the sedimentation chamber and the surface water of the main pool is introduced into the sedimentation chamber.

Physical filtration is suitable for placing filter materials such as cotton and brushes, and the biochemical filtration part can be placed with biochemical balls, bacterial houses, biochemical cotton, etc., and finally the part close to the clear water tank can be less oyster shells and other filters to regulate water quality. Do not use activated charcoal in filtration.

Ponding sequence, digging down - pipe repair - cushioning - reinforced concrete - four-sided pool wall - filter partition.

It should be noted that the pipe should be good, and it must be a PVC water supply pipe of the national standard.

Use a Jemoni fish pond filter to get it, Jemoni fish pond filter is the use of imported nano biochemical materials, permanent need to be replaced without manual cleaning, and self-cultivation, easy installation, save time and effort!

It is particularly troublesome to do the filtration by yourself, and the filtration effect cannot be achieved. Zhi especially recommends the West Daopu Koi Fish Pond.

Special filter, the only filter of the C-P Koi Fish Pond has passed the EU certification, the top ten brands in the country, and has reached the top technical level: 1Double-ion electrostatic filtration, 2

More than 100 kinds of beneficial bacteria beds, algae removal equipment, 4Blue light sterilization, 5Life expectancy more than 20 years, 6

Automatic backwashing, automatic blowdown.

After the fish pond is built, according to the size of the fish pond, choose a suitable filter, the effect is very good, the province also needs to build another filter pond, and regularly replace the filter material

You can refer to the filtration system of the Cali Fish Pond under Bai, which is mainly suitable for landscape water treatment

DAO garden rockery fish pond version purified, small.

Right area, villa koi fish pond filtration, etc. The moistening pond system mainly focuses on the functions of physical filtration, biochemical decomposition, sterilization and algae removal. It can make the landscape water crystal clear in 5-7 days. The disadvantage is that it cannot be used on pools that do not have a hardened bottom. Hope it helps.

<> the depth and size of the fish pond is not only related to the management and operation of the fish pond, but more importantly, it directly affects the stability and change of water quality.

The water quality of the fish pond with deep water accumulation is usually relatively stable, susceptible to wind and waves, and the dissolved oxygen content is high, which is also conducive to the mixed convection of surface and bottom water, and promotes the elimination of harmful gases, thus helping to increase the stocking density.

Water depth is closely related to water temperature. The water is too shallow, and the water temperature in the upper and lower layers is very high in summer, which not only reduces the appetite of the fish, but also causes death in severe cases. In winter, the water temperature in the upper and lower layers is very low, and the fish are prone to freezing to death.

The water depth and area are large, the water temperature is not easy to change suddenly, and the stratification phenomenon is obvious, and the water temperature of the middle and bottom water is low in summer and high in winter compared with the surface water, which is conducive to fish activities. But the deeper the water for fish farming, the better. Because the heat of water is higher than the solar thermal energy, and the absorption rate of water to light is very strong, generally at a depth of 30-50 cm, the sunlight energy is only about 15%, the oak or the sun is mainly heated by the surface water, and the photosynthesis and reproductive activities of phytoplankton in the water are mainly carried out in the surface water above 50cm.

The oxygen content of the middle and lower water is generally not high, and the natural bait is also less. It is improved only by the horizontal and vertical flow of wind and external forces. Therefore, the fish pond should not be too deep, and it should not be small and deep.

The shape of the fish pond is rectangular in the east-west direction, and the aspect ratio is 2-4:1, which can relatively prolong the sunshine time, which is beneficial to phytoplankton for photosynthesis and increase the amount of dissolved oxygen in the water. In winter, the east-west fish pond can also appropriately increase the temperature of the pond to promote fish feeding.

Hello, I'm glad to answer for you. The water in the fish tank filter tank is full to the next filter tank, probably because of the following reasons:1

Clogged inlet and outlet pipes: If there is debris in the inlet and outlet pipes or the filter screen is blocked, the water flow will be reduced or even unable to flow to the outlet, so that the water level of the filter tank on one side will rise. 2.

Tank height difference: If the height difference between the two filter tanks is too large, it will also cause the water from the fish tank filter tank at the height to flow down the pipe to the next filter tank at the bottom level. 3.

Too little filter material: If the filter material of the fish tank is insufficient or not dense enough, the water cannot be effectively filtered, and the water will pass through quickly, and at the same time absorb water from another filter tank, causing the water level of the filter tank next door to rise. To solve the above problems, you need to:

1.Clean the inlet and outlet pipes to ensure smooth flow; 2.According to the different height difference of the water tank, the water level of the fish tank filter tank should be adjusted appropriately to achieve a balance; 3.
