How to build a pure natural ecological fish pond?

First, the bottom design of the fish pond.

1. 1, the design of fish pond bottom, according to the unique beaches and different temperature differences in four seasons, needs to simulate the fish feeding activities in natural ecological areas. The height difference at the bottom of the fish pond needs to be considered. Differences can be designed according to the size of the family courtyard. Mother Xiaoshu suggested that the height difference should be between 1.2m-0.3m, not too deep, because most families have children, and too deep is not safe for children. Of course, the bottom is too flat to simulate ecology.

2。 According to the size of the courtyard, shallow and deep areas with or without slopes can be designed. The pond originally designed by the mother tree is not gently inclined. When the water temperature is low in winter, fish will stay in deep water, and when it is hot in summer, fish will dive.

3。 The bottom of the pool can be paved with gravel, pebbles and a few large stones. What can a big stone do? It is to create a crevice environment and provide a space for fish to move and rest.

Secondly, there are two kinds of building materials for fish ponds. The first one is impervious membrane, and the second one is brick cement waterproof material. Most people will choose the second one. In fact, both materials are good choices, but in any case, we don't recommend tiles.

Thirdly, other fish pond materials, such as other fish pond materials and fish pond frames, need to consider the layout of water inlet and water outlet, so it is suggested to leave gaps in the design of water inlet. The fish pond can successfully form the effect of falling into the water by circulating water and selecting booster pumps with different powers according to the size of the landscape nozzles in the fish pond.

Fourthly, the construction of ecological fish pond environment, the choice of fish pond plants, according to the ecological environment, try to simulate the natural environment of fish life for the family ecological fish pond. Before building a fish pond, the bottom of the pond was covered with a layer of natural lake mud. This mud has three advantages: 1. High viscosity, which can remove the water quality that is not easy to be turbid at the bottom of the pool; . Conducive to the purification of water quality and the growth of aquatic plants, water lilies, lotus roots and other plants.

Fifth, self-adhesion of microorganisms can purify water and increase oxygen. Choose plants that can purify water and look good, such as water lily, lotus, iris, reed, calamus and so on. Choosing plants that are easy to reproduce, such as water hyacinth and duckweed, according to the size of a family fish pond, may cause hypoxia in the fish pond. In the choice of plants, don't pursue too much, focus on suitability and practicality.

Sixth. The choice of fish pond species, snails are essential species in fish pond ecology. Snails are a good choice for many species (especially snails that can't breed quickly). You can buy it in the market or dig it by the river. It can eat microorganisms and algae in water and play a certain role in purifying water quality. In addition to raising koi fish, fish ponds can also raise a small number of river shrimps and small turtles (if turtles are not raised, it is easy to sink mud and muddy the water), such as crucian carp, anglerfish, benthic fish, etc. These fish usually do not surface in the pond, and fish feed residues can be discarded.

Seventh, the maintenance of the ecological fish pond, the fish pond has been built, and the later maintenance is very important. We need to follow the principles of one appearance, two changes and three cleanness.

1. Look: the water quality characteristics of fish ponds and ecological fish ponds are different from those of oxygen pump ponds with filtration systems. The temperature is low in the morning, and the water quality is particularly clear and the visibility is high on cloudy days; At noon, when the temperature is high and the weather is hot, the water quality will be turbid and the visibility will be low. Many people think that the water is not clear, whether it is the water or the fish pond. Actually, this is a normal phenomenon. Don't go into this misunderstanding.

2。 Change: water body replacement in ecological fish ponds. In summer, the water in fish ponds is particularly easy to evaporate, and algae are easy to reproduce. It is necessary to replenish water and change water regularly. The principle of water supply is that when the temperature is not so high in the morning or at night, it will not affect the temperature difference. If the temperature difference is too large, the fish will not survive. The principle of changing water is to observe the clarity and visibility in the morning or cloudy day. If the water quality is not good and the definition is not high, you need to consider changing the water. Of course, it is not necessary to change water frequently, but it needs to be specific. Water should be replaced with half of the total water.

Eighth. Clean up 1, clean up fallen leaves, floating dust and algae and duckweed growing too fast in the pool.

2. Clean up fallen leaves and floating dust with a net bag; Clean the net bag directly used by algae and duckweed with the net bag.

3. Plan the time and clean the fish pond regularly. Physical filtration mainly removes suspended solids, gels, dust, leaves and other impurities in water by selecting appropriate filter materials to maintain the clarity of water. The traditional simple method is to use stones and sand to seep water to remove visible suspended impurities. The invention has the characteristics of simple operation and low cost, but the purification effect of the fish pond is not good. Chemical filtration is to remove ionic compounds dissolved in water that are harmful to fish by chemical adsorption.

Commonly used chemical filtration materials include activated carbon, phosphate, ion exchange resin, etc. Compared with the physical filtration method, the purification effect of this method has been improved, but it still cannot achieve the purpose of fish pond purification. Biochemical filtration mainly uses biochemical bacteria attached to the filter medium to oxidize fish manure, bait residue and nitrogen-containing organic matter or ammonia. It is a commonly used fish tank filter in China. The commonly used biochemical filtering materials include fiber cotton, brushes, biochemical filaments, biochemical balls and so on. The effect of biochemical filtration is better than physical filtration and chemical filtration, but daily maintenance and cleaning are more troublesome, so a good biochemical system needs to be established.

4。 The system integrates physical filtration, biochemical filtration, sterilization, algae removal and circulating oxygen, adopts advanced nano-material movement in Germany, and through unique physical and biochemical separation and decomposition such as precipitation, biochemistry, ultraviolet sterilization, algae removal, backwashing, etc., precipitates impurities in water into the physical filter box, and then fully decomposes and degrades substances such as nitrate and ammonia nitrogen to form a pure natural ecological fish pond and purify water quality. The invention adopts food-grade stainless steel, which has the advantages of less investment, small floor space, long service life, up to 15-20 years, no need for manual cleaning, and good cleaning effect.
