Buying guide for the best 40 gallon fish tank

Priority is given to fish tanks that are glued without braces

The aquarium is one of the most common household items. People often use hidden glue without braces. This is a very professional firm if you play aquarium or aquarium; if you do not know what this tank looks like, you can refer to the article below. In this section, we will only advise on how to choose the right glasses.

There are cases where the tank is 70 cm or more in height for lakes that are too large, you must have braces to ensure safety, but the glass is still computerized and hidden glue.

Limit buying old aquariums

Many of you do not know what braces are like? These are glass panels glued on the tank’s surface, as shown below, are used to fix and increase the tank’s safety.

Unless you want to save money and are not ready to invest in a quality aquarium, refrain from buying old glasses, thin glasses, and braces. These tanks are designed to keep fish, not to play in the aquarium by its very nature. There are many reasons for this: aesthetics, safety, and professionalism, completely inferior to the glue hidden without computer grinding.

Make use of existing old aquariums

If you have an old aquarium that has been in use for many years and the glass is 5 cups thick, you want to take advantage of it as an aquarium to save on the cost of buying a new aquarium. It is okay, but be aware that the sole must be sure and only play simple aquascape compositions. Suppose you do not support the base and put many details into the tank, for example, playing very heavy. 

In that case, with rocky aquarium layouts, the risk of tanking and cleaning the house is very high because the bottom glass cannot withstand the floating force. It can also be dangerous if there are children at home.

As shown below, this iron leg does not support bearing if the thin tank is very dangerous, so the row of iron bars supports the bearing for the bottom glass.

We tried an old 5-meter lake and played with the waterfall stream layout, which I left in the yard. In the middle of the night, we heard the rush of water. Without opening the door, I knew what was going on because many people had shared experiences. The aquarium is broken! But since the lake is too old, I don’t care.

Choose to buy a new aquarium

First, you refer to the common sizes of the aquarium that people often play, then measure where your house corner is right to place the tank; we can adjust the size as you like, suitable with their home space, there is no need to form the right size that other people often play, however, it is necessary to consult the construction unit in cases where the size of the lake is too unusual.

If you have chosen to buy a new tank, your number one priority is still glazing with computerized glue.

Use glasses of 8 mm or more

For lakes with a length of 90 cm or less, you can use 8mm glass. If the length is greater than 90, I suggest that you use glasses of 10 or more for safety; if the tank is over 1 meter, then 12 mm or more is extremely sturdy and safe to use. Depending on your economic ability, the thicker the surface of the tank glass is.

Since the glue-hidden aquarium can only be made with a height of 50 cm or less, if you can afford and want to make a large aquarium, about 80 – 90 cm in height, you need to New braces that are sturdy enough.

You may want to change the size of the aquarium shortly

If you have a spacious house and begin to love the beauty of the aquarium, consider carefully before investing in a relatively small tank to practice playing, for example, a small pond with the size of 60 x 40 x 40, because when you know how to play aquatic. Successfully, i.e., plant a beautiful green tree, the chances of you will liquidate a small tank to buy a bigger tank for your passion. I have met a lot of customers in this case.

So if you want to play a big tank, say 1m2 x 50 x 50 for example, and are concerned that you have no experience, feel free to play, and if you are reading this article and contact me, I will show you each step carefully to be able to play successfully. Note that you do not have to buy from me to advise me; you still advise if you do not buy.

Once you have chosen the right size and type of watch for your needs, the next step is selecting and matching the lights. For example, a lake 1m2 x 50 x 50 must use a lamp with enough capacity to light the lake. If the lamp is too weak, of course, the tree can not grow or even die.

Some tips when setting up the aquarium

  • You should not release the fish immediately but wait for the tank to settle for at least 3 days. It is best to stock the fish one week or more, then make sure there will be no death due to unstable water.
  • If you have ground soil, you should change the water 30-50% for the first days without fish. And you should plant the whole plant at setup time and release the types of water ferns or algae because these types can grow fast. The newly set up lake will have abundant nutrients because it will be abundant; if not controlled well, it will cause harmful algae.
  • With the family of goldfish, carp, you should not play aquatic, should not have gravel, ground because this is a species with a lot of habit and stools.
  • When pouring water into the lake, you should put a tissue or some plastic bag and pour the water over. Allow the water to run evenly, not to cause strong currents to disturb the soil or plants.
  • Should drop a few food pellets to create waste, to start microorganisms. If there is no food during the lake’s creation, the microorganisms will starve as much as possible.

Release the fish

  • Choose to buy fish that are suitable for the tank with the right density. Predictive later population growth factor or fish grow up. Goldfish can grow up to 20cm. Choose healthy fish that show no signs of disease.
  • Do not pour fish directly into the tank immediately. Use a needle, poke a few small holes in the plastic bag then leave the plastic bag in the tank. Allow the water to flow in slowly into the bag so that the fish can adapt to the water environment and temperature of the aquarium.
  • Cut the plastic bag and add the fish after 30 minutes.
  • If you already have fish in your tank, you should consider isolating newly purchased fish and disinfecting it with saltwater first. To avoid new fish getting sick, the fungus infects old fish.

Maintenance and cleaning

  • A 30% water change should be done once a week, even if your water is not cloudy. The new water addition will add minerals to fish, shrimps, and aquatic plants. And you should add a little more microbes later.
  • In the event of a water change of more than 50%, split up several replenishment times.
  • If the tank’s microbiology is stable, the fish feces will only turn into harmless sludge. When itchy eyes, you can suck it out, so that is the main aesthetic problem.
  • Do not clean the filter and change the water at the same time. If your tank has a high density of fish, changing the water and rinsing at the same time will blow away a large number of microorganisms. And this will affect the stability of the tank. Fish will easily weaken because the concentration of NH3, NO3 increases because of a temporary lack of microorganisms.

FAQs

What is the cause of aquarium water in aquariums or muddy?

First, the aquarium water is turbid because the aquarium and aquarium water filters are still new. At this time, the amount of microorganisms in the aquarium is not stable, leading to the lack of water in the lake.

Second, the lake water is cloudy due to the algae contained in the aquarium too much. This makes the tank water cloudy and turns a moss green color. At this point, you should install a UV filter to eliminate harmful algae.

Third point, dirt from stone objects, aquatic plants, lake decoration accessories. Dirt will accumulate underneath the tank floor, and this phenomenon will be improved after a few days.

How long should the lighting equipment be left on?

With designing aquariums, we only need to let the lighting system for 8-10 hours/day be enough when the lights are turned on when the sun rises and then is quiet.

In addition, if the lights are turned on continuously, it can cause the aquatic animal to wilt because of too much light. In addition, some types of aquarium fish should also have time to rest at night. Too bright lights will affect the circadian rhythm of aquatic animals and make the fish flock easily to die.

Do aquarium fish need sleep?

This question is interesting! Quite a lot of you think that aquarium fish living in water should be “extremely alert.” The fish is still sleeping! The only thing is that animals are sensitive to light and to sound. That’s why such a mistake only happened.

Like most animals, aquarium fish sleep at night. So turn off the decorative lights so that the fish can rest!

What is the right time to release aquarium fish into an aquarium?

Certainly, when you first start making an aquarium, the owner should not rush the fish in immediately. Please wait 1-2 weeks; the microbiology and water conditions of the lake are stable for the aquarium fish to be introduced.

Why is there a lot of algae in the aquarium?

Even though the aquarium is properly designed and cared for, there will likely be algae. Explaining the above, experts have pointed out the following reasons:

  • First, algae appear due to an imbalance of nutrients in the water. One more point, too much light, low CO2 content, and less substrate are also the causes of many algae.
  • Second, there are many slow-growing algae in the aquarium. So the owner must remember to regularly clean and clean algae on the glass.

To be able to stabilize the number of algae inside the tank, there are many options. For example: planting more bushy trees to prevent harmful algae. Or the owner can completely add more aquarium fish to eat all harmful algae. Where algae are too many and grow, it is possible to use specialized chemicals. In particular, do not leave excess food in the tank excessively. If dead aquarium fish, they must be taken out immediately. Thus fish carcasses will not be decomposed and partly limit the algal blooms.
