The path to large tanks of 150 & 175 gallons
It has been proven over the past couple of decades how largely spread the aquarium fish-keeping has become. Most of us begin our aquarium journey from a very young age, first by keeping some Goldfish, then some live breeders, and then moving to some larger community tanks of up to 40 gallons approximately.
We then start to master some of the basic principles of keeping an aquarium, including filtration, fish stocking and breeding, feeding the right amounts at the right times, species compatibility, and so forth. Once these principles have been mastered, we typically begin with more advanced species like Angelfish or Discus, which demand larger tanks of a minimum of 55 gallons.
You may also be interested in our well-detailed list of 50 & 55-gallon aquariums.
Now, fish-keeping is also driven by a high level of curiosity which naturally implies that we have a strong desire to get started at some point with a saltwater tank as well. When that happens I’d strongly recommend getting started with a nano reef tank, cycled properly, with the right cleaning crew and aquarium accessories, and perhaps a couple of Clownfish later on.
We listed below the top tanks currently available in this category and after that we’ll dive into more specific details, like stocking, tank dimensions, filtration needs etc.

Should I switch to a 150-gallon tank?
Naturally, if time and budget allow us, then yes – getting a 150 gallon tank or even a larger one, is absolutely worth it!
150 gallon tanks stocking ideas
If we talk about freshwater species, then the options are quite wide. Let’s list below some potential freshwater stocking ideas for a 150 gallon or larger tanks:
- Discus (about 14), Corydoras Sterbai (the Starbai Corys are the best to tolerate higher temperatures), a small school of Rummynose or Cardinal Tetras (about 14 as well), a school of Otocinclus (these guys work non-stop doing a great job, and they aren’t messy compared to Plecos for instance).
- Angelfish (about 8-10) although it depends on how many breeding pairs they’ll form as that can trigger some territorial disputes, a small school of Rummynose or Cardinal Tetras (about 14 as well). plus a cleaning crew of Corydoras and Otocinclus/Plecos depending on what’s your preference.
- Oscars and Plecos as cleaners
- African Cichlids
- Black ghost knife fish and a school of Rainbowfish
- Or simply a large community species tank
When it comes to stocking a 150-gallon tank with marine species, one should carefully pay attention to their compatibility. If plenty of freshwater species can play along with each other, that’s not the same with marine species.
There are plenty of species out there that aren’t even compatible with their own kind unless they can establish large territories.
For instance, this is a lovely marine stocking for a 150 gallon FOWLR tank:
- One Clownfish
- Flame Wrasse (Pair)
- Leopard Wrasse
- White Tail Bristletooth Kole Tang
- Goldflake Angelfish
- Naso Tang with Streamers
There are literally endless marine stocking combinations for such stunning tanks. You basically need to pay attention to the compatibility of the species, but also to corals, ensuring the fish won’t be nipping at the corals.
150 gallon tanks dimensions
These tanks are typically quite large and in a rectangular shape. It is becoming as well quite the standard, to have a cabinet or stand coming with the tank as well, but some manufacturers give you the option to have only the tank shipped, without any stand.
That saves up a lot of money and some aquarists prefer that, as they’ll simply build the stand themselves for a much lower cost.
Below there’s a table with approximate tank and weight dimensions for 150 & 175 gallon tanks:
|Tank size||L x W x H||Empty weight||Filled weight|
|150 Gallon||60″ x 24″ x 24″||338 lbs||1838 lbs|
|175 Gallon||59″ x 19.7″ x 31.5″||391 lbs||1870 lbs|
150 gallon tanks build materials
These larger tanks are relatively newer compared to other smaller tanks at least. They are all built using high quality, tempered, and very transparent glass. Such glass material is extremely durable and highly resistant to all sorts of scratches.
Top of it all, the visible light transmittance through this glass is greater than 91.5%, despite the thickness of the glass which is roughly about half an inch.
The stands are as well sturdy ones, capable of properly handling great weights, but also offering large cabinet areas for the sump and other accessories, fish-food, etc. The tanks listed in our top come with either reinforced wooden stands or even better metal ones, highly resistant to saltwater erosion.
150 gallon tanks accessories
Most of these tanks come equipped with included filtration systems and media, powerful LED lighting for sustained and healthy coral growth, water pumps, and some even include a protein skimmer as a bonus so to say.
The plumbing and setting up of such a large tank of 150+ gallons can be a daunting task. Fortunately, though, the aquariums listed in our article, come with clear and effective installation instructions. One of the tanks comes without a stand, but the other 3 have a stand as well, available in different nuances, they have a sump, and all the plumbings and accessories included.
Should you consider that adjacent filtration is necessary for your tank, you can relate to our recommended aquarium canister filters review.
Some useful information: as a rule of thumb, the total filtration GPH capacity should be around 5 times higher than the total capacity of the tank – so for a 150-gallon tank, you should aim for about 750+ total filtration GPH. The higher the bio-load, then the higher the GPH.
Next to the extensive and efficient filtration, for marine aquariums, it’s highly recommended to make use as well of a protein skimmer. The protein skimmers come in great aid to your existing filtration, removing any uneaten fish-food or waste before they even begin their breaking down process to smaller particles.

Covering all the significant aspects regarding large tanks such as 150 and 175 gallons ones, let’s pick up and go through the details of all the aquariums listed here in our article.
1. SC Aquarium W/ Stand – Overall Best 150 Gallon Aquarium with Stand
SCA 150 Gallon Aquarium with Maple Wood Cabinet
For saltwater fish-keeping enthusiasts looking for an upgrade to a 150-gallon tank, that literally includes everything, look no further as this is the ultimate best kit you can get.
In short, it’s built using the best aquarium glass available and includes all the necessary equipment to plug and play the perfect saltwater environment.
It doesn’t even need a protein skimmer, since the pack already includes one that can handle tanks of up to 180 gallons.
Best built aquariums
The SCA Aquariums is a relatively newer aquariums manufacturer, but it does everything by the book. Their tanks are made of low iron glass, 12mm euro braced. Now, what does the euro bracing refer to?
Euro bracing, when we talk about fish-tanks, it’s referring to the single strips of glass which are placed around the top of the tank, and held by silicone. This ensures extra resistance and safety for the tank, without compromising any space and visibility at the top of the tank, so the LED lights can still operate at their maximum efficiency.
Going one level lower, in below the tank, we can notice a strong and durable maple wood cabinet.
The cabinet is housing a 68-gallon sump with ATO reservoir built-in (Automatic top off units), with all the needed compartments, mandatory for a successful saltwater aquarium. The protein skimmer capable of handling up to 180-gallon tanks is also included in the package, making this a great deal, as you won’t have to spend anything extra to purchase a separate skimmer.
Aquarium dimensions and plumbing
Looking at the tank itself, leaving aside the stand an any other components, these its precise dimensions:
- 60″ L x 24″ W x 24″ H and it’s made of 12mm thick glass
Built-in the tank as well, is an overflow box with three holes already drilled. This box can be extremely useful if you choose to purchase the tank without a stand and its main sump, but decide to go with a custom environment. Such an overflow box is a great entry point to set up a sump.
Furthermore, if you do decide to purchase the full kit, then these dimensions should be of great help, when determining what’s the best location to place the tank:
- 62″ L x 25″ W x 36″ H – Maple wood cabinet
- 52″ L x 17″ W x 17.75″ H – 68 Gallon sump
- SCH40 Standard size plumbing kit

It does come though with the same built-in overflow box, ideal for a HOB protein skimmer and filtration media.
Stunning quality glass
For the price, there simply isn’t a better 150-gallon fish tank. The SC Aquariums are all made of starphire glass. This refers to the type of low-iron glass that provides an extremely high clarity compared to standard glass types.

An aquarium that’s adding style
How many aquariums out there do really stand out for an amazing look? It’s true that nowadays most of them look beautiful, but lots of them aren’t even close to the amazing image produced by the JAJALE aquariums. These aquariums are simply ideal for any professional office, but also for the ordinary living room, which will surely be brighten up by such a splendid aquarium.
Such a display is created by the amazing color combinations, the crystal clear tempered glass, but also by the composition of the cabinet and aquarium frame. These are reinforced using a resilient titanium and magnesium composition, ensuring a long lifetime.
Outstanding filtration & powerful pump
Among the included accessories, we have to mention the powerful water pump that operates at 45W, generating 1200 GPH, which is just the perfect flow rate for such a large tank. The entire filtration system and operation are nicely hidden in the aquarium stand so you won’t be bothered by any external wires or tubes – simply enjoy the aquarium display!

The kits combine colors like red, white, gold, brown, and black creating truly amazingly looking aquariums and stands.
Improved sump and filtration capacity
The filtration chamber comes equipped with a patented box that aims to facilitate a 360° rolling filtration system. To explain this process furthermore, the separation box basically allows the water to enter through its lid where it reaches the filtration system.
At the bottom of the box, there are numerous holes that allow the water to exit the box in a uniform manner, ensuring a more effective filtration and way less noise generated compared to other filtration systems. Using this advanced filtering system, the water will stay clear for such extended periods, so that you won’t have to change more than 2/3 of the water about 1-3 times per year.
The separation box’s lid shows where the water is going to enter in the filtration chamber.
At the bottom of the box we can notice the area where the water will exit the box in a dripping process, generating a significant lower noise level.
Furthermore, we’ll explain the entire filtration process that occurs in a sump that’s considerably larger compared to other similar systems.
