1. Tetra 20 Gallon Complete Aquarium Kit w/Filter Heater LED & Plants
Tetra 20 Gallon Complete Aquarium is the perfect size as both an aquarium and an ornament. It is a perfect size as I mentioned, not too big nor too small. I heard this is a starter kit for whom has just begin learning how to build a large fish tank. I think with that price, it is one of the cheap large fish tanks I have ever known. The aquarium is fitted with a heater with an adjustable temperature. The temperature meter is placed outside the tank wall. As a starter kit product, the heater and filter have done a great job in its role.
I don’t like the adorned decorations that are available except the anemones. Fish tanks are attached to a lighting system, ColorFusion lights. I quite like the light emitted, also do you know the LEDs can be changed? To turn on and off the light, just hold down the power button. The lamp has two modes, one can change color continuously and one monochromatic projection mode.
2. SeaClear Acrylic Aquarium Combo Set
If you feel tired of the traditional aquarium with a familiar box shape, SeaCleaar Acrylic Aquarium is exactly what you need. With a unique beautiful exterior tank, the aquarium welcomes many compliments from fish owners. SeaClear consists of two versions including octagonal aquarium version and traditional rectangular boxy version.
And of course, I bought an octagonal aquarium. In addition, the aquarium also has 3 different colors, you can choose the color you like. The aquarium surface is made of acrylic, I appreciate the light durability of this aquarium. It does not cause water to spill after being filled.
All fish tanks except the lid are made transparent, you can observe the whole aquarium without any dead corners. The black plastic lid covers the top of the tank to maximize the protection of the fish inside. The lid is also equipped with a 20-watt bulb that can adjust the light strength to facilitate the development of aquatic plants and animals.
3. Glofish 20 Gallon Aquarium Fish Tank Kits, Includes LED Lighting and Décor
My daughter said she loves to raise something, so I bought her some jellyfish and a house for them, Glofish 20 Gallon Aquarium Fish Tank. I have to say for a beginner aquarium, this product is doing very well. Do not believe it? It has all the necessary supplies and equipment for fish farmers to get used to. A kit includes a water filter, heater, decorations, fish food, and water conditioner pack.
I quite like the fake decorative colorful plants. Combining LEDs on the tank lid, fake branches in particularly vivid under the light blue light. You will be amazed at the performance of this filter. It was hard to hear the noise from the filter. If someone said that the Glofish 20 Gallon Aquarium Fish Tank filter regularly made noise, I bet he had installed the wrong way. Also, the fish tank kit has a lightstick that glows very nice! I love it.
4. SCA 50 Gallon Starfire Glass Aquariums Complete Package 24x24x20 “10mm
Beautiful appearance, it was my first impression when I first saw SCA 50 Gallon Starfire Glass Aquarium. One thing I really like about this aquarium is that it comes with a partition for the aquarium. You can insert partitions to create a labyrinth so that the fish can be animated and not just boringly swim.
Nearly everything is integrated with this aquarium from water purifiers, air pumps, bulkheads, tubing, pipes to decorations. The water filter is placed inside the tank in the back of the color with a black background. This increases beauty and slimness for aquariums. In addition to the tank, there is also a black pedestal to create an elegant feel. I’m sure a large fish tank with cabinet will be the best choice for home or office decoration.
This is a saltwater aquarium, so if you need to keep freshwater fish, you can tell the distributor to remove the unnecessary equipment.

The base of the aquarium is also very beautiful and durable. It was a black frame framed around the tank body. A solid fish tank has a beautiful appearance but it has a modest price. You can be assured when using Aqueon fish tank. Its capacity is 20 gallons, very suitable for small fish species.
6. Aquaficial Jellyfish Tank (Large Tank)
I raised three jellyfish so the 5 or 10 gallon fish tanks were too small for them. I had to choose large fish tanks or even an extra large fish tanks as a new place for them. Finally, a friend introduced The Aquaficial Jellyfish Tank to me. It amazes me about its ability. The aquarium has a water-proof system with two air pumps located on either side of the head of the tank providing air for the fish, creating and regulating the flow. My 3 jellyfishes really like this large fish tank.
LEDs system allow you to press the button and the light will automatically change color. If you don’t like it, you can also have a single color light.

How to build a large fish tank
1. Choose the size of the aquarium that suits your needs
Usually for large fish, large amounts of living space or large numbers of fish, you should choose large fish tanks.
When pouring water into the tank, remember that the water is very heavy. Normally 10 pounds of water will correspond to a 1 gallon tank.
Also, the size of the tank depends on the position of the tank. You need to calculate the tank location from which to estimate the most accurate aquarium size.
2. Use annealed glass
The incredible strength of this type of glass makes it the first choice when making large fish tanks.
Glass types used for laminated glass tanks will depend on the water level, using 8mm, 10mm or 12mm glass.
Many people still think that the bottom glass side stands the most pressure of water. But in fact, the volume of water, rock, and soil that put gravity on the bottom and put it through the foot of the aquarium is the safest side.
3. Foot basin
– Depending on economic conditions, you can choose the type of tank foot that suits you.
– The height of the foot of the tank is the height from the ground to the upper edge of the tank, about 0.6m to 0.8m. If it is too high, it will be difficult to clean the aquarium. That is, whether you stand, or sit, you can still see the aquarium at eye level, not bending down or looking up to see the aquarium.
How to maintain a big fish tank
Regular cleaning the aquariums will help to eliminate fishy smells and residues inside the tank. In addition, it will create a stable living environment for fish species, as well as making the aquarium become as sparkling as the new purchase. Here we would like to point out some of the most appropriate vivarium cleaning tips.
1. Clean the glass surface and the bottom
Keeping the fish tank glass clean is the first job to ensure a healthy environment for the fish.
The best way is to buy a cleaning kit and use it to clean the glass surface inside the tank before each water change time.
Glass tanks should be kept clean both inside and outside to ensure a clean living environment for the fish as well as beautify the house.
When conducting cleaning, you should not take everything out of the aquarium. Useful bacteria plays a biological filter, everything in the fish tank is their home indeed. Removing and cleaning the decorations in the lake will contribute to collisions or even kill these bacteria, thereby reducing the quality of water filtration.
2. Purify the aquarium water
You need to purify the tank water once a week. What you are really doing is changing a part of the water in the tank, about 10-20%. Replacing only a small amount of water will make the aquarium look more beautiful and clean again. Meanwhile, the amount of beneficial bacteria needed for fish remains in the tank.
After changing the water, use a suction nozzle or vacuum to clean gravel and decorative accessories in the tank. Fill the water again.
You should only withdraw 10-15% of the water in the aquarium and then replace it with new water (sedimented and chlorinated water). If your water filter is placed under pebbles then it is important to wash the gravel as this will help prevent residues and decomposing organic matter from choking the gap between the pebbles and blocking the water flow. In short, if you absorb 10-15% of the water in the tank, you can clean 25-33% of the stones.
3. Control green algae
One thing you will notice pretty quickly after buying and raise fish tanks is slimy green algae that begin to form a lot on the tank wall. To control algae, it is important to properly sanitize.
If the algae are closed on the ornament, you should use a tool to scratch the algae layer and rub the surface of the tank before changing water. Currently, all kinds of aquarium care tools are sold at ornamental fish shops. Besides, to keep the tank cleaner, you can drop some glassfish. Their food is algae and dirt on the glass surface.
However, there are a few types of aquarium fish that are particularly fond of algae, such as the Plecostomus fish. It will never win any beauty contest, but this little fish is very fond of algae. Not only that, but the Common Pleco also eats anything in the tank, including dead fish. You can raise Common Pleco as an algae control solution, keeping the tank clean.
Even if you have algae-eating species, it is important to replace 10-15% of the water in the tank every week to extend the life of the aquarium. Once you get used to this, the job will become easy.
In addition, you can use UV lamps to kill algae in aquariums.
4. Clean the filter
If the water filter in the tank needs to be renewed, you should not change all the equipment inside the filter immediately as this will affect beneficial bacteria. Since then, your aquarium must return to the first stage to create new bacteria. Clean new filter devices before installing them in the system (in case the instruction manual for filtering equipment is allowed).
Depending on the size of the aquarium, you may have one or more filters to keep the fish healthy. Cleaning the filter is an important step of maintenance. Remember that these parts are covered by beneficial algae and bacteria, which are part of the need for healthy fish to live. Replacing all parts also at the same time can cause imbalance for fish habitats. Therefore, you should only change one by one for easy adaptation.
5. Pump water into the aquarium
After absorbing about 10-15% of the water in the fish tank, you need to replace the equivalent amount of new water. To do this, the simplest way is to use a plastic tube to pump water from a bucket into the aquarium. This will help you avoid spilling water as well as stain gravel and decorative objects.
Don’t forget to use bleach to remove chlorine in the water before pumping water into the tank. When pumping water, place the bucket in a place higher than the top of the tank and only for about 2 minutes to fill your tank. Furthermore, you need to watch the pump to avoid the outflow of water or water from the pool when full. Remember to keep a distance between the water surface and the mouth of the tank because sometimes fish need to rise to the surface for oxygen.
6. Clean gravel
The gravel at the bottom of the fish tank is the storage of everything that is too heavy to float in the water, which is the leftovers and fish waste. If you have a large fish tank, you will want to buy a built-in vacuum cleaner for aquarium cleaning. It will remove dirt that is lurked between the stones without sucking up the gravel.
Gravel hygiene is essential because gravels store a lot of uneaten food and fish waste, polluting the water environment, directly affecting the health of the fish.
Conclusion
Large fish tanks need to meet certain conditions in order to win consumers’ love. To avoid wasting time choosing between different products, you can refer to the above tanks for more advantages and disadvantages of some types of aquariums. Wish you soon find your own aquarium.
