1. Solidity
Commonly used fish tank materials include glass and acrylic. In order to withstand the huge water pressure, the appropriate thickness must be selected to create a safe aquarium. Tank, generally the thickness of the tank wall of a fish tank over one meter is best to reach 1CM, and so on. Of course, it is better if you choose a finished acrylic tank.
2. Shape
Common fish tank shapes include rectangle, square, circle, polygon, etc., which can be chosen according to personal preference, purpose and home environment.
3. Length
The length of the fish tank can be selected according to the purpose of the display. Generally, it can be matched with the size of the lamp to achieve the best effect and economic benefits.
4. Width
For the purpose of placing light tubes, the width of a 70-120CM tank should be above 40, preferably 60CM, so that 4 sets of light tubes can be placed and there is depth. Convenient for landscaping.
5. Height
The water level height should generally be between 50CM and 60CM, mainly for the penetrating power of light waves! Higher than 60CM will affect the penetration of fluorescent lamps. Metal halide lamps should also be below 67CM. Besides, a tank that is too high will not be convenient for future maintenance (you have to reach down). Of course, if it is lower than 50CM, it will affect the overall appearance ( More than 2 meters is a separate matter, but pay attention to the choice of foreground).
6. The support of the tank stand
The water volume of the aquarium is (length*width*height/1000). One liter of water is equal to one kilogram, so the bracket must be able to support the weight of 1.2 to 1.5 times the volume of water to ensure safety (we also need to consider factors such as sand and rocks in the future).
7. Bottom sand
Generally, coarse river sand is commercially available. You can also use fine river sand (based on grass: such as sun grass), black gold sand, white sand (easy Dirty) high-end ones such as silica sand, silica sand, basal fertilizer sand, etc. Note that only water figs can survive in alkaline water, so generally you cannot use coral sand or other alkaline sand or stones.
8. Filtration system
Not for price and space considerations, of course, the bigger the better, the more the better, because this is one of the most important links, in a limited space It is very necessary to choose a set of filtration equipment suitable for your own aquarium in the space. Since the concepts of most domestic players have not changed yet, we will not introduce the top equipment for the time being! Within this range, I recommend a combination of an external filter pump and a built-in pumping motor. Note that it is best to use an external model one size larger than the one recommended by the manufacturer. For models above 1.8M, it is recommended to use two! If you have the financial resources to add a quicksand filter and change the pumping motor to a "black diamond", it would be better.
9. Carbon dioxide
This is a link that is easily overlooked by junior players but is also very important. We know in junior high school biology class: Plants produce carbon dioxide during the day (photosynthesis). ) absorbs CO2 and releases O2, which is the opposite at night. The general CO2 concentration should be 10 to 20 PPM to meet the needs of aquatic plants. Of course, it should not be excessive (it will both make the fish hypoxic and reduce the PH value). I would like to remind you that the so-called CO2 tablets and powder generators on the market are both It has no actual effect and may have negative effects. Only using CO2 cylinders or powered carbon chip generators can have actual effects, which is the most direct.
10. Constant temperature system
Note: One liter of water requires one watt of power. In terms of species, tuber grasses such as negative aquatic plants and net grass, platinum grass, etc. need to be kept below 26 degrees (preferably 18 to 22 degrees), while red aquatic plants like high temperatures to grow well at 26 to 30 degrees.
