Unchanged salinity: When starting to make a box of seawater, just pay attention to the ratio of 30 liters of seawater per kilogram of seawater.Most of the adjusted seawater pH is maintained at 8.0~8.4, and the density is 1.020~1.024.The content of nitrous acid is below 0.1 mg/L.After the aquarium is in operation, the normal water will evaporate, which will cause the water level to decrease and the density of the water to increase day by day. Fresh water must be added at intervals to compensate.After making up for fresh water, Zhang must check whether the density of the water is appropriate.It should be emphasized that the temperature must be stopped below 25°C when measuring salinity.At present, the advanced mechanical tool for measuring the salt content is a conductivity meter for measuring seawater. The conductivity value of the scale seawater should be between 47 and 51 milli-Siemens/cm. Chen commonly used buoy or box density meters.Unchanged pH: Anyone who has raised seawater and admired fish knows that it is extremely important to maintain a constant pH in the aquarium.Because the pH of the water in the aquarium will drop due to the residual of nitrite and nitrate, it must be tested regularly to avoid the deterioration of the water volume, which will cause discomfort and infection of the fish.You should know that the common large and small white spot diseases commonly seen in seawater are mostly caused by excessive pH changes. You should pay attention to it: you should adjust the pH and accurately monitor its changes during the next period, which will be easier.Control white spot disease of marine fish.The oblate fish tank is light in weight, the load is not easy to be squeezed and deformed, and the outside is small and exquisite, suitable for feeding small ornamental fish

Check the filter system regularly: ① If Zhang uses a filter outside the box, after cleaning, the water pipe must be connected.Note that the water pump can both filter the water in the tank and pump out the water in the aquarium.② Frequently check whether the amount of water flowing out of the filter is normal and whether there is infarction.In addition, the biological cotton or filter element that blocks dirt should be cleaned regularly and replaced regularly.③Activated carbon should be changed regularly.④ Regularly clean the dirt in the protein separator.⑤ Clean the filter regularly (methods described earlier).Appropriate lighting Appropriate lighting refers to the illumination that preserves and reproduces the unicellular zooxanthellae that can maintain the symbiosis of invertebrates.Chen Mou has already discussed the requirements of different creatures for their different lighting requirements. There are strong light, medium light and weak light.Chen can give an example. A 130 cm long aquarium with a depth of 60 cm is equipped with two 150-watt metal halide lamps at a distance of 40 cm from the water surface. It is enough to shine for 10 hours a day.Zhang Mou can be deduced by analogy. Can Zhang Mous aquarium be connected to suitable lighting conditions?Both of these antiseptics can effectively release active oxygen, thereby killing microorganisms and bacteria in the water
The filtering effects of the two filtering systems are very good, but there are also disadvantages. The trickle filtering needs to occupy a large space in the upper part of the fish tank, which is not wonderful.
Acrylic sheets produced by Shanghai Blue Lake Aquarium Engineering Co., Ltd. are all cast at one time, and the maximum pouring thickness can reach 350mm. Compared with the composite thick plates on the market, it also shows the advantages of compressive resistance and fracture resistance.
?The fish tank should not be placed under the gods-no gods are suitable for placing the fish tanks, especially under the god of wealth and the three stars of Fu Lushou, otherwise it is "the god is going to the water", and there will be money breaking!The fish tank should not be aligned with the kitchen stove. The fish tank is aligned with the kitchen stove. The two are in line with each other, which is very bad, because it will damage the health of the family.The number of fish farming in the home is the number of joint fish farming based on the number of books.A good way to have a good home is to raise some goldfish in the fish tank.Nine goldfish are kept well, eight of which are red or gold, and the other is black.If the goldfish you raise accidentally dies, just buy it to make up.While studying, Chen thinks that the reason why the fish will die is because of the doom for his family.Dont raise goldfish in bedrooms, latrines or kitchens.Even worse in the bedroom will make you bear the loss of material, Dalian is stolen and even robbed.Therefore, it is better to raise fish in the living room or outside the house. It is absolutely not wrong to place the fish tank in the north and southeast.But it also depends on the situation of the house.In order to clarify the probation of the fish tank, we must pay attention to the space position of each Hengyu.The financial position of the house is suitable for placing a fish tank. Generally, it is at the diagonal position of the entrance and exit. It is impossible to place pure objects, and the corners and floors will not be damaged.Never be in the center of the house.The southeast and south of the capital are Dalian, and the success of the career is in the north, so it is better to place the fish tank in the southeast or north, so that it can be placed at the quick and favorable entrance, that is, the front of Mingtang, which can be used as an office indecent., Imagine a wonderful fish tank, green eyes full of vitality, help relax, improve the body, and expand interpersonal relationships.The selection of Dalians orientation must be based on the learned space and orientation.1. After a long period of low temperature and lack of sunlight in winter, the goldfish in early spring are weaker. At this time, they began to move to outdoor outdoor environments. The fish exchange of the fish needs to be extra careful. Once a day, you can also change it every other day.The amount of water is well controlled at about% of the total amount of water
Relevant knowledge and details, the depth of the traditional home appreciation of the fish tank experience does not exceed 60cm, it is appropriate to touch the bottom of the tank with the palm of a person, and the adult can barely manipulate the fish tank when standing, so the overall height of the traditional fish tank and the base is determined to be the human armpitLower height, do not exceed 1.2m-1.3m, some up to 1.5m, that is for the big man, or a special fish farmer, of course, such a high fish tank must be prepared for fear of hardship. The specifications of the TV set only say a few inches diagonally, and the specifications of the traditional household fish tank only say the length. Because the height of the traditional fish tank is limited by the manipulation, so all the household fish tanks on the market are fixed by length, Dalian 1.2m, 1.5m, 2m fish tank, etc., then the height is usually only 1.2-1.3m.Specification of wall-mounted fish tank, Dalian: 1.25m×0.6m×0.The ecological mural of 10m can be seen that the height of the wall-mounted fish tank is limited to less than 80cm.The presentation of the negative pressure fish tank breaks through the depth of the home fish tank as long as 60cm and the height of the fish tank as long as 80cm, with floor cabinet 1.2-1.3m, not exceeding 1.5m limit.When a large number of algae appear in the aquarium, aquarists or farmers can control the growth of algae by adjusting the hardness of the water, the temperature of the water, and the pH of the water.
Generally speaking, the pH and the concentration of nitrous acid and nitrate should be measured every two weeks in the aquarium. The pH should be maintained between 7.9 and 8.3. If it is a newly established seawater aquarium, test the pHMany times.When the pH of the water in the aquarium increases or decreases, you can stop the adjustment by using the alkali-removing agent (adjusting the pH) or the acid-removing agent (adjusting the pH).Generally, it should not exceed 0.1. If the adjustment exceeds 0.1, it can be stopped repeatedly and gradually adjusted to the required pH.However, if the water in the aquarium has just been adjusted and the pH drops quickly, then remind Zhang that the water cluster tank needs to be changed.·Regular water changes: nitrate cannot be synthesized by nitrifying bacteria, and the cost of some removal methods is too high. When nitrate accumulates to an inevitable level, it will incur a large amount of algae such as Chaetoceros, hair algae, filamentous algae, brown algae and even red algae.Overgrown.That not only affects the beauty of the Dalian aquarium, but also inevitably damages the fish or creatures, thereby destroying the ecological balance of the aquarium, and incurring pan tanks.Therefore, regular water changes should be performed in daily procedures, and 10% of the seawater should be replaced every month (purify the water under the gravel with a gravel suction device).Pay attention to participate slowly in the new seawater, draw in with a thin tube to stop the water from changing too fast and fish.At this time, the advantages of the special-shaped fish tank can play a big role, its light transmission performance is very high, can reach %, most of the light energy can be absorbed by it
