There is something serene about watching beautiful fish tanks. It helps ease the mind, and no one can deny that. While keeping a fish tank comes with a fair share of challenges, it offers many benefits that make everything worth the while. If you are looking forward to becoming a fish owner, then you need to be prepared for the difficult choices that you will be required to make. Buying a beautiful 150-gallon fish tank is not as simple as going into the store and picking it up from the shelf. You need to do your research first. Here is where we come in.

Today we are going to help you figure out what is the exact fish tank that you are looking for. While finding the legendary Aqueon 150-gallon aquarium or the Marineland 150-gallon aquarium from a reputable retailer might be difficult, we promise that you will be impressed by the seven great fish tanks that we have reviewed for you today. The rule of thumb when picking the aquariums that we are going to present was that they all should be of premium-quality. Thus, there is no wrong choice here. Pick the one you like the most, and you are good to go.

Before we get into it, we do need to mention that a big 150-gallon fish tank aquarium is not the ideal weight and dimension for a first-timer. The reason behind this is those big aquariums need lots of maintenance. You also need to keep in mind that if you don’t purchase an aquarium that comes with a full kit that contains a stand, you will need to find a proper place that can withstand the weight of the tank when it’s filled with water. The additional items that you will require for maintenance, such as chemicals and cleaning kits, for example, will be more expensive for bigger tanks. If you want to start out with something smaller, then you can always check out a 75-gallon55-gallon, or even 40-gallon aquarium.

We are going to kick things off with the 150-gallon fish tank from SC Aquariums. As the fish tank’s name implies, the stand-out feature is the Starfire Glass. This is a special type of glass that is made from low-iron silica, which is much clearer than standard glass. Therefore, your fish are going to look amazing, especially if you use lights and dark background to highlight their colorful scales.

The aquarium is euro braced with a built-in center overflow. If you are unfamiliar with the term “euro braced,” then you should know that this is the feature that ensures the glass does not “slide” off the bottom and cause leaks. This is what makes the aquarium a great choice for someone who doesn’t want to worry about the risks brought on by the weight of the water.

Furthermore, the aquarium has three holes that are drilled inside the overflow box for extra security. The drill holes can fit a 1″ SCH40 bulkhead. Luckily, the folks at SC Aquariums bundle the aquarium with a plumbing kit so that you don’t have to purchase one for yourself. To make things even better, the manufacturers are so confident in the quality of their product that they are offering 3-years’ worth of warranty.

Pros:

  • It includes a plumbing kit;
  • It uses euro bracing for protection;
  • It ships with ultra-clear Starfire Glass;
  • It features all-black backing
  • It uses an overflow box for extra security

Cons:

  • It does not ship with a stand
  • It’s heavy

The runner up is the Red Sea Reefer XL, which is a 139-gallon aquarium. What makes it stand out from all the others featured on our list is the rimless design. This is an excellent feature for hobbyists who want to create extraordinary decors that include plants and a thick substrate layer. If the rimless design is not impressive enough, then you should know that the folks at Red Sea have used ultra-thin front and side glass. The glass thickness measures in at 15 (5/8″), and therefore, you will have no problem showing off your fantastic fish.

We also want to highlight the fact that this fish tank is equipped with an integrated automatic top-up system. By buying the Red Sea Reefer XL, you will also get an elegant cabinet that features a comprehensive water management system. This includes a professional sump, which is great because you will no longer have to purchase it separately. The sump works together with the automatic top-up system to provide a silent down-flow system. This system is nice to have because it guarantees a stable water flow. Additionally, Red Sea also includes a self-assembly kit.

Pros:

  • It includes a beautiful cabinet stand;
  • It ships with an integrated automatic top-up system;
  • It uses ultra-thin glass;
  • It features a rimless design;
  • You will get a free self-assembly kit;

Cons:

  • A bit on the expensive side

If you are looking for something simple that is ideal for beginners, then you can’t go wrong with the Clear-For-Life UniQuarium 150R. This fish tank features an elegant design that gives you more than enough room to include all types of fish and plant life that you want to display. The manufacturers have used the best and most durable acrylic material when building the aquarium in order to make sure that it can provide a safe and happy home for your “aquatic friends.” Picking an acrylic aquarium is always a safe bet because they are brighter, more reliable, and stronger than regular glass. Not only that, but acrylic does a great job of acting as an insulator that prevents temperature fluctuations.

One of the best things about the Clear-For-Life UniQuarium 150R fish tank is that it comes with a built-in filtration system. This is excellent news because filtration systems for big aquariums are quite expensive. The water capacity of the Clear-For-Life UniQuarium is 125-gallons, and it features the following dimensions: 72″ (L)x24″ (W)x20″ (H). The aquarium doesn’t come with a stand or cabinet, but luckily, the manufacturers are making up for that by offering a limited lifetime warranty against leakage. This shows us that the manufacturers are more than confident that their product is of premium quality.

Pros:

  • It offers a limited lifetime warranty against leakage;
  • It is equipped with a built-in water filtration system;
  • It uses acrylic (more durable than glass);
  • It is available with three background color options;
  • It is used for both freshwater and saltwater fish;

Cons:

  • It does not include a stand

The cabinet contains a 68-gallon sump that is equipped with a built-in ATO reservoir. To top it all off, the SCA 150-Gallon Aquarium is bundled with a 650 GPH return pump.

Right from the first glance, you will notice that this 175-gallon aquarium looks extraordinary. It’s built from ultra-transparent glass that features a light transmittance of 99%. If you are worried about durability, then you can rest assured knowing that the manufacturers have reinforced the aquarium with an aluminum frame that is resistant to saltwater erosion, corrosion, and deformation from the pressure put on by the water.

This is a 139-gallon aquarium that stands out from the previous models with its dedicated 3W moonlight channel that provides the perfect lighting for nighttime viewing. Since we are talking about the premium features that this aquarium has to offer, want to highlight the fact that it also ships with a single optical-glass and hollow lens that can be used to create a homogenous light.

Aquarium Buying Guide

A lot of research goes into finding the right aquarium and setting it up just the way you want to. Planning is the key to success when buying a new aquarium, and there are a couple of factors that you need to consider before deciding on what to purchase. Check them out below.

The Size

The first thing that you need to decide is the size of the fish tank. This is quite important because it determines how many fish you will be able to keep inside of it. Even though going for a big aquarium right from the start may seem exciting, this is not a wise decision. You will spend lots of time on maintenance, and you will need a bigger budget. Whatever tank size you decide to purchase, you should make sure that it is sturdy and that it ships with a stand. Finding a place that can support the entire weight of a 150-gallon fish tank is not easy.

Glass or Acrylic

The second crucial factor that you should consider when buying a fish tank is what materials it is made from. There are only two options that you can pick from – glass and acrylic. Glass is usually the most popular option because it is cheaper, and it doesn’t really get any scratches. Although, there are some downsides to using glass. The glass will make your aquarium heavier, especially if it’s a 150-gallon one. Moreover, glass can shatter easily, and it only comes in square and rectangular shapes.

On the other hand, we have acrylic fish tanks that stand out with their clarity. Using acrylic aquariums is the best way to ensure that you always have a good view of your aquatic friends. The problem with using acrylic is that it is prone to getting scratches and to yellowing with age. Not just that, but acrylic is also more expensive because it comes in unique shapes.

Open or Closed Top

Another crucial decision that you need to make is if you want a fish tank with an open top or a closed one. Open tops look very good, and they use suspended or clip-on lights. While open-top fish tanks might look cooler, the lack of a top is causing evaporation to happen quicker than usual. Pollutants such as dust can also get in the water, and this means that you will need to filtrate the water more frequently than usual.

Tanks with a closed top are usually cheaper, and the “hood” can be used to hide the lights. This will make the inside of the aquarium look better, but you will only be able to view it from a single angle. Luckily, you can get the best of both worlds by choosing a fish tank that features a removable hood that comes in the form of sliding glass or with a hinge.

Frequently Asked Questions

In case you are still undecided if a 150-gallon fish tank is what you want and you have some questions left unanswered, then you should check out the FAQ below.

How long is a 150-gallon tank?

Aquariums come in many sizes, starting as small as 2.5-gallons and going up to 200-gallons. The mistake that most beginners make is that they fail to consider the dimensions of a big fish tank. The dimensions of a tank may differ if it has a unique design, but in general, a 150-gallon tank will measure in at 72″ x 18″ x 28″ (length x weight x height). In addition, a filled fish tank of this size will weigh in at 1800lbs.

How many fish can be in a 150-gallon tank?

If there is one thing that all fish owners have done at least once, then it has to be wondering just how many fish they can fit in their aquariums. Sadly, there isn’t something like a stocking chart to tell you the exact number. This leads to many hobbyists overcrowding their fish tanks. The general rule of thumb when stocking a fish tank is one inch of fish per gallon. Although, you need to take into consideration that fish also need enough room to swim.

Will my floor hold a 150-gallon tank?

The short answer is yes. As previously noted, a fish tank of this caliber weighs in at around 1800lbs. It is worth noting that you will need a special stand. If your fish tank doesn’t come with a stand, then you will need to purchase one yourself. A regular table will snap in two if a 1800lbs object stays on it for more than a couple of hours.

Can you over filter a fish tank?

Water filtration is vital to the aquarium’s ecosystem. This is why it’s highly advised to do the proper research before getting into this hobby. Coming back to the question, you cannot over filter a fish tank. The reason behind this is that the water can never be too clean. The only negative impact is that the movement of the water may stress the aquarium’s residents.

What is the best lighting for a tank?

Generally, most specimens will do great with little light or ambient light that comes from the surrounding room. With that said, the most popular lighting option for fish tanks is LEDs. This is thanks to the fact that LEDs are durable, and they do not overheat, unlike bulbs that can and will heat up the water
