How To Choose Best 40-gallon Fish Tank

Select the aquarium

The type and size of aquariums depend on the available space, the cost and the needs of the fish. Remember, bigger tanks are easier to take care of than smaller ones. The reason why large tanks are less of a hassle is that they have more dispersed water, more space to decompose waste, and the environment more stable. For example, the temperature of a 10-gallon tank may be affected more quickly by sunlight or at a cooler night than the 55-gallon tank. A 55-gallon tank tends to have a much more stable pH than a 10-gallon tank.

Select the tank location


The first condition for the location of an aquarium is in an area that can support its weight. Very heavy water, about 8 pounds per gallon (about 1 k / l). For example, a 20-gallon tank weighing more than 160 pounds does not include gravel or teeter-totter. When a location that can support such weight is found, verify that the location meets other requirements. The tank should be kept out of direct sunlight, this will encourage the growth of algae and can affect water temperature. Avoid placing the tank near a window or door in an empty area that can cool the tank. Similarly, the tank should be cleaned of all heating equipment (stoves, ovens) that will overheat the tank.


Unfortunately, the cost is often an important factor in choosing the type and size of tanks one can afford. Glass tanks are generally cheaper than plexiglass tanks. Usually the smaller the tank, the lower the price (except for tanks under 10 gallons). The least expensive tanks are usually mass-produced tanks, such as 10, 20, and 55 gallons.

Fish needs

Before choosing a tank, the type and quantity of fish should be considered. Consider the size of the tank that the species requires. For example, a dragonfish or an Oscar cannot exist in a 10-gallon tank. Although it is not necessary to decide what type of fish you plan before you buy your tank, for best results, decide between buying.

Type of Fish Tank

The most common materials used for tanks in the United States are glass and mica sheets. Both of these materials seem to work well for aquarium keeping.

Glass tanks are preferable because they are widely available at relatively low cost. Glass tanks, manufactured by reputable manufacturers, are usually reliable enough to leak. However, some inexpensive production tanks are prone to leakage and breakage. Make sure the tank you buy is guaranteed to leak for a while. All glass tanks are heavy.

Plexiglass tanks are becoming popular in the United States. These tanks are lightweight, attractive, and available in many sizes and shapes. Plexiglass tanks are less likely to leak than glass tanks. There are some disadvantages including the higher cost of the glass tank and the possibility of scratching. Some reports that big tanks can “bend” over time.

There are other tanks, but they are not nearly as common as the two mentioned types.

Whichever tank you choose, make sure a cover is included. The casing will reduce evaporation and reduce the chances of fish jumping

Fish Tank Shape

Aquariums are available in some shapes, most commonly rectangular. Rectangular tanks are great for residential fish because they often have large areas for exchanging gases. However, the so-called “large” tanks with the little area are not suitable and need strong aeration. In general, large tanks cannot support large fish loads like shallow tanks.

Other shaped tanks, such as hexagons, cannot support as many fish as a rectangular tank, due to the smaller area. Hexagonal tanks do not allow long, open, swimming rooms.

Installation of Fish Tank

  • Place the aquarium in an appropriate location.
  • Clean the inside of the tank and check for leaks.
  • Add any introductory or counterproductive remarks outside the back of the tank.
  • If using cable heating, add the cable according to the manufacturer’s instructions.
  • If an under gravel system will be used, add the dish.
  • Add all the rocks or wooden decorations, fix them to the position with lines. Heavy rocks should sit on the tank floor on a sponge.
  • Add low fertilizer to the growing tank. Follow the instructions on the package for proper allocation.
  • Wash gravel away to remove dirt and other unwanted particles. For this, a bucket can be used and gravel can be removed from the bucket with a sieve.
  • Add gravel. If possible, use gravel from an established reservoir to cultivate nitrifying bacteria. Supporting gravel also stabilizes rock structure. If the gravel is “exchanged for cash” or “ladder”, add the appropriate structures to do so.
  • Filter settings. If possible, use some filter media from a set tank to speed up the “cycle” process.
  • Install a heater and the thermometer.
  • Start adding water. Use fresh with lukewarm water of Luc (68-72 ° F, 20-22 ° C). Add water with a hose, and spray water over rocks or into containers so that gravel is not disturbed. Add water conditioner to water.
  • When the tank has finished half of the full tree can be added. The selected plants must be healthy and fast-growing plants such as Vallisneria, Hygrophila, Java moss, and Amazon sword. Plant tall plants along the back of the tank and plants grow low in the foreground. Sensitive plants such as Cryptocoryne should be added after two or three months.
  • Installation of lights.
  • When the kettle is full, the heater can be plugged in (assuming it has been submerged for 20 minutes).
  • After an hour or more, when the hot light goes out, check the temperature. If the temperature is different, then adjust the heater accordingly.
  • Check the pH and hardness of the water to see if its properties are suitable for the type of fish you want to keep. The pH can be manipulated with chemicals available at pet stores.
  • Once the temperature has stabilized, a limited amount of healthy fish can be added. Suitable fish include strong tetras, burrs, and Danios zebras. Leave the bag to “float” in the aquarium for 10-15 minutes before opening the bag to allow some water in. Wait a few minutes and allow more water to break into the bag. The process could be continued for more sensitive species to adapt gradually. Net produces fish and transfers them from bags to tanks. Do not allow any bag water to enter the tank as pet store water is often less than desired and can be treated with medication.
  • Put the lid on the aquarium.
