The above common handmade aquarium reference size meets most visual viewing specifications. p>

The above is the reference size of common handmade tanks, which can meet most of the visual ornamental specifications, and can be modified according to the actual site conditions.

Traditional home ornamental fish tanks experience the depth of the maximum of not more than 60cm, in order to touch the bottom of the tank with the palm of a person's hand is appropriate, adults can barely stand to operate the tank, it determines the overall height of the traditional fish tank and the base of the height of a person's armpit, not more than 1.2m-1.3m, some as high as 1.5m, that's for the Russians to build a big man, or a special fish enthusiasts, of course! Such a high fish tank has to be prepared for the idea of not being afraid of thousands of pains. The specifications of the TV only say how many inches of its diagonal, and the specifications of the traditional home fish tank only say the length. Because the height of the traditional fish tank is limited by the operation, so the market usually said that the home fish tank to the length of the specifications, such as 1.2m, 1.5m, 2m fish tank, and so on, then its height is usually only 1.2-1.3m. wall-mounted fish tank specifications, such as:1.25m x 0.6m x 0.10m ecological mural, you can see that the height of the wall-mounted fish tanks are generally limited to 80cm or less. The emergence of negative pressure fish tank, breaking the home fish tank depth of only 60cm, the height of the fish tank is only 80cm, with the floor cabinet 1.2-1.3m, no more than 1.5m limit.

Then the specifications of the negative pressure fish tank must indicate the shape of the fish tank, ornamental surface size and operating height.

For example, an interactive negative pressure fish tank specification on the right:

Body size 3200*2380*720;

Ornaming surface 2260*1500;

Operating height 1100.

A home negative pressure fish tank specification:

Body size 1480*1980*600;

Operating height 1100.

Ornamental surface 1280*1000;

Operating height 1200.

A square aquarium specification:

Body size 1200*1200*2480;

Ornamental surface height 1250;

Operating height 1240.

Identify the good and the bad

Reminder: the most important thing is to find a reputable and guaranteed aquarium. thing is to find a reputable manufacturer of fish tanks for sale with a guarantee.

Glass market 5MM glass is still mostly ordinary glass (3MM float domestic just developed, not easy to see), but more than 8MM glass are generally used float glass (relatively high transparency), so the general used to do the thickness of 8MM aquarium, do not have to worry about whether to cut corners, but the handmade tank is done to carefully observe the surface of the surface with or without scratch, bubbles, broken corners; glass adhesive; glass is also a good way to identify the bad, but not a good way to identify the bad, the most important thing is to find a reputable manufacturer of fish tank sales. However, after the handmade tank is done, we still need to carefully observe the surface to see if there are scratches, bubbles, broken corners; whether the glass glue is uniform, whether there is wear air bubbles (before the fish tank is done, we need to talk to the store to determine what kind of glue to use, and the store should be held responsible for any problems).

The glass market is also a lot of poor-quality glass, differentiation method is very simple, good manufacturers of glass thickness will not be less than a trace, and poor-quality glass, 5MM is actually only 4.5-4.8, 8 = 7-7.5, 10 = 9.5, 12 = 11, must pay attention to the choice.

Daily Maintenance

Control of stable water quality

-Stable salinity

When you first start to modulate a tank of seawater, just be aware of the ratio of 30 liters of seawater per kilogram of seawater salt can be modulated. Most of the modulated seawater pH is maintained at 8.0 to 8.4, density of 1.020 to 1.024.0, nitrite content of 0.1 mg / liter or less. After the operation of the aquarium, the usual water will evaporate, will make the water level down and the density of the water increases day by day, it is necessary to add fresh water every once in a while to give supplement. After replenishing the fresh water, you have to check if the density of the water is appropriate. It should be emphasized that the temperature of the salinity measurement must be below 25℃. The most advanced equipment for determining the salt content is the conductivity meter for measuring seawater. The conductivity value of standard seawater should be between 47 and 5 1 milliSiemens per centimeter, and we commonly use a buoy or box densitometer.

- Stable pH

Anyone who has kept saltwater ornamental fish knows that maintaining a stable pH in the aquarium is extremely important. Because the pH of the water in the aquarium can drop due to residual nitrites and nitrates, it must be tested regularly so that the water quality does not deteriorate, causing the fish to become unwell and contract diseases. It is important to know that the majority of the common large and small white spot disease in saltwater ornamental fish are infected due to excessive changes in pH. Special attention should be paid to the fact that pH should be adjusted and correctly monitored during the medication period, so that it will be easier to control the white spot disease in saltwater fish.

Generally speaking, every two weeks the aquarium should be tested for pH and nitrite and nitrate concentrations, and the pH should be maintained between 7.9 and 8.3. If a saltwater aquarium has just been set up, it is best to test the pH more often. When the pH of the aquarium water is raised or lowered, you can use the alkaline agent (high pH) or acidifier (low pH) to adjust, but slowly, not to be raised or lowered too much at once, generally not more than 0.1, if the adjustment is more than 0.1, can be carried out several times, and gradually adjusted to the required pH. However, if the aquarium water just adjusted soon, the pH and quickly down, that reminds you, the The aquarium needs a water change.

-Regular Partial Water Changes

Nitrates cannot be broken down by nitrifying bacteria, and some removal methods are too costly. When nitrates accumulate to a certain level, they can lead to algae such as Trichoderma, Haplocarpus, Filamentous Algae, Brown Algae, and even Red Algae in large clusters. This not only affects the aesthetics of the aquarium, but also infringes on the fish or organisms to a certain extent, thus destroying the ecological balance of the aquarium and leading to flooding, which is not to be dismissed as serious. Therefore, in daily management, we should do regular water changes, and change 1 0% of the seawater every month (use a gravel suction device to pump dirty water under the gravel). Pay attention to add new seawater should be added slowly and pumped in with a thin tube to avoid the water quality changing too fast and irritating the fish, etc.

-To check the filtration system regularly

①If you use an out-of-box filter, be sure to hook up the hose after cleaning. Note that the pump can both filter the water in the box and pump out the water in the aquarium.

②Check frequently that the amount of water coming out of the filter is normal and not clogged. In addition the first layer of dirt-blocking biofoam or cartridge should be cleaned frequently and replaced regularly.

③Activated carbon should be replaced regularly.

④ Regularly clean the dirt in the protein separator.

⑤The filter should be cleaned regularly (the method has been told earlier).

Suitable Lighting Suitable lighting is the light that can sustain the survival and reproduction of the unicellular wormwood algae that are born in invertebrates***. We have already discussed that for different organisms their light requirements are different, there are strong, medium and weak light. As an example, a 130 cm long aquarium with a depth of 60 cm, fitted with two 150 watt metal halide lamps at a distance of 40 cm from the surface of the water, is illuminated for 10 hours a day. You can then make an analogy as to whether your aquarium is maintained under proper lighting conditions.

Appropriate water flow

-Circulating water flow

Because nitrifying bacteria consume a very high amount of oxygen in the process of nitrification, how to feed sufficient oxygen and organic matter to be decomposed in the water evenly into the filter material within the water circulation process, so that the nitrifying bacteria can decompose it efficiently and effectively, is a very important point to consider in designing the circulating water flow. We must realize that too large a water flow will make the nitrifying bacteria have no foothold, can not generate a dense nitrification network. Too slow water flow and can not achieve the function of transporting oxygen and organic matter, resulting in some dead space, resulting in anaerobic zone, the accumulation of unnecessary ammonia and hydrogen sulfide and other exhaust gases, in turn, is not conducive to the stability of water quality.

-Forceful water flow

Water movement allows for constant water replacement in every part of the aquarium, such as corners, cracks, caves, and around corals. We must try to prevent areas where the water is static. The movement of the water allows the metabolites of the unicellular worm Flavobacteria on the invertebrates to be removed by the movement of the water. And food for the organisms would be sent near the habitat of the organisms due to current action, making it easier for them to feed.

Combining the above, the water flow in the aquarium is very important, using a circulating pump to create a water flow circulation rate of at least 5 times per hour in the aquarium is more desirable, using two pumps so that the water flow every 6 hours to change the direction of the water flow, timed to turn on and off, it is even better.

Application of Live Bio-Rocks

Setting up and maintaining live bio-rocks (live coral reef rocks) is important for a perfect saltwater aquarium. These live "rocks" will give you "surprises" if you give them some time. Countless algae and organisms will regrow, making the small coral reef ecosystem into an independent and complete biosphere once again. With the presence of live corals, the aquarium will be easier to raise saltwater ornamental fish and marine organisms, and why this is the case is still under study, but it does work, and that's the important thing.

These living stones are coral reef rocks taken from the bottom of the sea, on which a large number of marine organisms have survived, and which can be placed in the aquarium to produce the same natural ecological organisms that were present when they were on the bottom of the sea. However, these living creatures in the collection, handling, transportation process, encountered sun and wind, and air contact, so that many living creatures die, if not treated directly into the aquarium, the remains of these dead organisms will need to nitrify the decomposition of the box, in the aquarium has just been established in the nitrification system does not have enough nitrifying bacteria to nitrify the large number of pollutants, so that the water quality will be worse to become This will make the water quality bad and become cloudy, and even have a bad odor. Therefore, the use of live rock requires proper packing and transportation, as well as proper cleaning. For the first 4 to 6 weeks, we regularly cleaned the living stones with a water jet every week, and it is safe to put the cleaned living stones in the water only. Alternatively, we can use sun-dried biotite and rinse it well before putting it into the aquarium. In conclusion, it is important to use live rock, but be sure to clean it well.

Checking the water temperature

To keep tropical seawater ornamental fish and invertebrates, it is important to keep the temperature of the aquarium within the range of natural tropical seawater, that is, between 25 and 27 degrees Celsius. Calcium corals will stop synthesizing calcium when the temperature is below 20℃ or above 30℃, and the temperature exceeds the range of 15 to 32℃. Most corals die. Therefore． In the feeding management, it is necessary to install cooling and heating equipment as appropriate, in order to prepare for high temperatures in summer and winter cold. When heating the aquarium in winter, because of the high conductivity of seawater, use a heater with a grounding wire. So as to protect the user. The best safety measure is to install a 24-volt low voltage heating system. If the fish are gathered in one place, if the number of heads is not correct, you must carefully identify the fish that are not coming over to eat the bait and further observe these fish, is it because they have a bad appetite, or do they not want to get along with the other fish? If you find dead fish, you must fish them out immediately to avoid contaminating the water. Is the death of the fish caused by disease? Is the death of the fish due to disease or injury caused by other fish attacking the fish? It is important to find out why. It is worth noting that saltwater ornamental fish are very sensitive to any pressure or interference, so when observing the fish, use your eyes, not your hands, and try to avoid putting your hands into the aquarium.

Fish tanks and home feng shui

Fish tanks should not be placed under the statue of God - any statue of God are not suitable for fish tanks, especially in the God of Wealth and the three stars of fortune and longevity under the three stars, or else it is the "God of the water", there will be a financial ruin! The place!　　Fish tank should not be the kitchen stove - fish tank on the kitchen stove, the two into a straight line opposite, it would be very bad, because it will be detrimental to the health of the family.　　The number of fish in the home feng shui is based on the number of Luoshu to match the number of fish. A good way to have good feng shui at home is to keep some goldfish in the fish tank. It is best to keep nine goldfish, eight of which are red or gold in color and the other is black. If any of the goldfish you keep accidentally die, simply buy more to replenish them. In Feng Shui, we believe that fish die because they block bad luck for the family.　　Don't keep goldfish in your bedroom, toilet or kitchen. It is even worse in the bedroom, as it can cause you to suffer material losses, such as theft or even robbery. Therefore, it is better to keep fish in the living room or outside the house, and you can never go wrong by placing the fish tank in the north and southeast. But it also depends on the condition of the house.　　In order to place a fish tank, you must pay attention to the space orientation of each house. House of wealth suitable for fish tanks, generally in the entry and exit of the diagonal position, can not be placed in the clutter, corners, floors can not be peeled and damaged. Never placed in the center of the house. Southeast of the main money and wealth, career success in the north, so it is appropriate to place the fish tank in the southeast or north, it is best to be placed in the induction of rapid and favorable entrance, that is, the location of the front hall, which can also be used as an office landscape, the design of a beautiful fish tank, full of green and vitality, help to relax the nerves, improve the spirit, expanding interpersonal relationships. The choice of auspicious directions shall be based on feng shui to calculate the planning space and orientation.
