How to pick a fish tank, what do I need to pay attention to?

1, select the fish tank method is as follows:

1, first of all, select the fish tank attraction is the shape: common aquarium shapes are rectangular, square, round, polygonal, etc., according to personal preference, use and home environment to choose.

2. Length: The length of the aquarium can be chosen according to the purpose of the arrangement of the aquarium to choose the appropriate size, generally with the size of the lamp can achieve the best results and economic benefits.

3Width: For the purpose of putting the lamps in the tank, the width of a 70-120cm tank should be more than 40cm, preferably 60cm, so that you can put down 4 sets of lamps and have the depth to facilitate the aquascape.

4. Height: The height of the water level should be 50cm to 60cm, mainly for the penetration of the light wave! Higher than 60CM will affect the penetration of fluorescent lamps, metal halide lamps should be 67CM or less, and then too high tank is not convenient for future maintenance ah (to reach down), of course, lower than 50CM will affect the overall beauty (2 meters above the other, but pay attention to the choice of the foreground)

5, solidity:

Commonly used aquarium tank brands of glass and acrylic materials, etc., in order to withstand the enormous water pressure, and to provide a good environment for the aquarium to be able to withstand the water pressure, and to provide a good environment for the aquarium. In order to withstand the enormous water pressure, you must choose the appropriate thickness in order to create a safe aquarium, generally more than one meter of the aquarium tank wall thickness of the best 1CM, and so on, of course, if you choose a finished acrylic tank better.

6, the degree of support of the tank frame: the volume of water in the aquarium is (length * width * height / 1000). One liter of water is equal to one kilogram, so the stand must be able to support 1.2 to 1.5 times the weight of the water volume in order to ensure the safety (we also have to consider the factor of putting sand and stone in the future).

7, bottom sand: generally marketed as coarse river sand, you can also use fine river sand (based on grass: such as sun grass), black gold sand, white sand (easy to dirty) advanced such as silica sand, silica sand, fertilizer sand, etc., pay attention to the only banyan is able to survive in alkaline water, so generally can not be used in coral sand or other alkaline sand or stone.

8, filtration system: not out of price and space considerations, of course, the bigger the better, the more the better, because this is one of the most important aspects of the recommendation of external filter pumps and built-in lifting motor combination of combinations, pay attention to the external model is best to use than the manufacturer recommended by the larger than one, more than 1.8M is recommended to use two! If you have the economic conditions to add a set of quicksand filter, and then the water motor to "black diamond" is better.

9, carbon dioxide: plants in the daytime (photosynthesis) is to absorb CO2, release O2, at night is the opposite. General CO2 concentration should be 10-20 PPM to meet the needs of aquatic plants, of course, do not overdo it (both will make the fish hypoxia and will reduce the PH value) here to remind you of the so-called CO2 tablets of the city beasts and powder generator are no practical effect, and may have a negative effect.

10, thermostat system:

Note: A liter of water requires one watt of power. In the type of negative water plants and net grass, Buckeye Wave grass and other tuberous grasses need to be below 26 degrees (preferably 18-22), while the red system of water plants like high temperatures in the 26-30 degrees grow well.

Second, note: now the glass market inferior glass is also a lot of differentiation is very simple, a good manufacturer of glass thickness of a trace will not be less, and inferior glass, 5MM actual only 4.5-4.8, 8 = 7-7.5, 10 = 9.5, 12 = 11, must pay attention to the choice.

Main Types

I. According to the type of material:

(1). Ordinary glass --- emerald green, fragile, low transparency, easy to aging and deformation under the rain and sun, try not to be used to make fish tanks.

(2). Float glass - transparent float glass is glass paste through the control gate into the tin tank, due to gravity and its own surface tension effect floating on the surface of the molten tin, and then into the Xu cold tank, so that the glass is smooth and even on both sides, the ripples disappeared and made. Dark green, smooth surface without ripples, good perspective, with a certain toughness.

3. Tempered glass, laminated glass - tempered glass is a high-strength safety glass obtained by heating the glass to the softening point, and then sharply air-cooled. Under the same thickness, the bending strength of tempered glass is 4-5 times higher than ordinary glass, and the impact strength is 5 times higher than ordinary glass. Toughened glass has a strong thermal stability level and can withstand drastic temperature changes without destroying the ability. The most important feature of tempered glass is its safety, which is similar to honeycomb particles after breaking, which can avoid the harm to human body. Note: After tempered glass, it can not be cut, drilled, grooved and other processing. Because the glass is broken into similar honeycomb particles, completely irreparable, so it is not recommended to use on the aquarium!

(4). Acrylic glass --- close to the plexiglass and ordinary glass between a glass material, was originally used in airplanes, the early corner of the aquarium is also mostly used in pressed Kelley glass, lightweight, strong toughness, shall be made of one piece, easy to scratch (a little bit like the characteristics of plexiglass) less transparent!

(5). Plexiglass --- PMMA commonly known as plexiglass, is an important thermoplastic developed earlier, with better transparency, chemical stability, easy to dye, easy to process. But the strength is low, aquarium use in addition to some small craft cylinder (box), generally not used.

(6). Ceramic - ceramic craft aquarium suitable for home decoration.

(7). Stone --- There are many types, common are, jade fish tank, DuanYan stone fish tank, lapis lazuli fish tank, alabaster fish tank, marble fish tank, lapis lazuli fish tank, sandstone fish tank, travertine fish tank, and so on can be engraved with different patterns, patterns.

II. According to the structure of the form: rectangular, single arc, double arc, round, semicircular, wavy, spherical, cylindrical, circular, conical, U-shaped tanks, bullet and so on.

Three. According to the appearance of art: Chinese, European; modern, classical.

Four. According to the water quality: sea water tank, fresh water tank.

Fifth. According to the living organisms: fish tanks, aquariums, coral tanks, turtle tanks, ecological tanks and so on.

VI. According to the installation mode: screen tank, through the roof tank, wall-mounted tank, embedded wall tank, corner tank, window tank, desktop tank and so on.
