Quick answer: Buy a 150-gallon glass tank only if you have a 6-foot wall and a stand built for that load. The common U.S. size is 72.5 by 18.5 by 29.5 inches. Match the stand to the footprint before you order the glass.
Aqueon’s Standard 150-gallon tank measures 72.5 inches by 18.5 inches by 29.5 inches.
This page is a research-desk guide to footprint, glass, and stands. We did not fill these tanks, did not rank them, and did not add smaller display tanks or accessories.
Our research team analyzed published specs from maker pages and compared length, width, height, glass notes, and whether a stand is in the listing.
What we included and what we left out
A model is in this article only if the maker lists the display volume as 150 gallons.
That is the selection rule: the vessel must be a currently sold aquarium, and the maker text must say 150 gallons or approximately 150 gallons.
We left out stands sold alone, plus lids, heaters, and filters sold without a 150-gallon tank.
We left out every kit whose display tank is smaller than 150 gallons. We also left out systems that put “150” in the model name but hold a smaller display.
Aqueon’s Standard Glass Rectangle page lists 150 as a size, and Aqueon’s Reef-Ready page lists a 150 Gallon Rectangle. Those two stay in because both are 150-gallon display tanks.
Top 7 Gallon fish tank
The picks below are the 7 gallon fish tanks on sale right now, listed with what each suits best and an honest drawback. Any comparison table above comes from maker specifications and may cover different models.

Footprint: how much floor a 150-gallon tank uses
A 150-gallon label does not mean one floor shape.
Rockland Aquarium’s listing for the Aqueon Standard 150 Gallon states 72.5 inches by 18.5 inches by 29.5 inches. That box needs about 6 feet of wall and 18.5 inches of room depth.
Innovative Marine’s INT 150 Lagoon page lists 47.3 inches by 35.4 inches by 19.7 inches. That tank is shorter on the wall and much deeper front to back.
Acrylic Pros lists the Reef Pro 150 Tall at 48 inches by 24 inches by 30 inches. That is a 4-foot wall and a 2-foot depth.
Our research team compared those three published footprints.
- Aqueon Standard 150: 72.5 × 18.5 inches, about 1,341 square inches
- Innovative Marine INT 150 Lagoon: 47.3 × 35.4 inches, about 1,674 square inches
- Acrylic Pros Reef Pro 150 Tall: 48 × 24 inches, 1,152 square inches
The lagoon uses more floor area than the long Aqueon, while the tall 48-inch tank uses the least floor area.
Measure the wall and the walkway before you pick a shape. A deep tank can block a door even when the wall length looks fine.
Glass, braces, and overflows
Read the brace and overflow notes before you pick a 150-gallon tank.
Aqueon’s Standard Glass Rectangle page says large aquariums use one-piece center-braced frames. The 150 size is on that size list, and the line is sold for freshwater and marine use.
Aqueon’s Reef-Ready page lists a 150 Gallon Rectangle, and that tank ships with a MegaFlow overflow. The overflow kit includes a 3/4-inch elbow and a 1-inch bulkhead.
The same Reef-Ready page rates the single-molded overflow at 600 GPH. It also states a limited lifetime warranty.
Innovative Marine’s INT 150 Lagoon page lists 15 mm side glass and 19 mm bottom glass. It also lists a recessed euro brace and three 1-inch pre-drilled drains.
Acrylic Pros lists 12 mm (1/2 inch) glass on the Reef Pro 150 Tall. That listing includes a recessed euro brace and a center overflow.
Do not assume every 150-gallon tank uses the same glass thickness. The Aqueon pages we read do not publish a millimeter number for the 150.
Stand and floor load
A 150-gallon tank belongs on a stand built for aquarium weight.
Aqueon’s FAQ says filled aquariums weigh about 10 pounds per gallon. The same page says a 20-gallon aquarium weighs about 200 pounds when filled.
Using that 10-pound rule, a 150-gallon fill is about 1,500 pounds. That figure follows Aqueon’s example method and includes water, substrate, and décor.
Aqueon’s FAQ also says most household furniture will likely only support aquariums of 5 gallons or less. Larger tanks need a stand made for aquarium use.
Aqueon’s Standard page repeats the stand warning and says to place the aquarium on a stand that can bear a filled aquarium.
Acrylic Pros lists a 48 by 24 by 36 inch cabinet with the Reef Pro 150 Tall.
Innovative Marine’s INT 150 listing includes an APS aquarium stand. The same page lists a crated package weight of 480 pounds.
Our research team divided Aqueon’s 1,500-pound filled estimate by the Aqueon 150 footprint of 1,341 square inches. The load is about 161 pounds per square foot on the stand top.
Ask a building professional about joists if the tank sits above a basement, because we did not inspect any house.
Four current 150-gallon tanks compared
These four listings are all 150-gallon display tanks with different footprints.
| Model | Maker-listed volume | Length × width × height (in) | Glass and build | Stand in the listing |
|---|---|---|---|---|
| Aqueon Standard Glass Rectangle 150 Gallon | 150 gallons | 72.5 × 18.5 × 29.5 | Framed glass, center brace | Not included |
| Aqueon Reef-Ready 150 Gallon Rectangle | 150 gallons | 150 Gallon Rectangle size | Framed glass, MegaFlow, 600 GPH overflow | Not included |
| Innovative Marine NUVO INT 150 Lagoon | Approximately 150 gallons | 47.3 × 35.4 × 19.7 | 15 mm sides, 19 mm bottom, euro brace | APS stand included |
| Acrylic Pros Reef Pro 150 Tall | 150 gallons | 48 × 24 × 30 | 12 mm glass, euro brace | 48 × 24 × 36 cabinet |
Pick the Aqueon Standard 150 when you want a long 6-foot freshwater or marine box.
Pick the Aqueon Reef-Ready 150 Gallon Rectangle when you want factory overflow parts for a sump.
Pick the Innovative Marine INT 150 Lagoon when you want a short, deep reef footprint and published thick low-iron glass.
Pick the Acrylic Pros Reef Pro 150 Tall when you want a 4-foot wall and a 30-inch-tall water column.
Filter, water changes, and cycling
A 150-gallon tank still needs a filter rated above the tank size.
Aqueon’s FAQ says to choose a filter rated one size larger than your aquarium. Canister filters can hold many media types.
For how canister ratings are written, see our guide to canister filters for a 75-gallon tank. Use that method, then step up to a rating above 150 gallons.
Aqueon’s FAQ calls a 10% water exchange each week ideal, which is 15 gallons on a 150-gallon tank. The same page says changing about 25% once or twice a month is enough for most aquariums.
Avoid changing more than 50% at once. Aqueon’s FAQ warns that a large swap can shift temperature, pH, and chemistry too fast.
Aqueon’s FAQ says a decorated 10-gallon tank holds about 8 gallons of water. Plan for less than 150 gallons of real water after substrate.
Aqueon’s FAQ says most tropical fish prefer 76°F to 80°F, while goldfish and other coldwater fish prefer 65°F to 72°F.
Aqueon’s FAQ says planted tanks should get 10 to 12 hours of light, while décor-only tanks need 5 to 8 hours.
Aqueon’s FAQ says most experts recommend waiting at least 48 to 72 hours after setup before adding the first fish. Then the cycle still has to finish, so read how long to cycle a fish tank before you buy livestock.
Aqueon’s inch-per-gallon rule is one inch of adult fish per net gallon. That is a crude cap of 150 inches of adult fish, and activity and territory still cut that number.
A 150-gallon tank is far larger than the tank size a betta needs. Do not buy 150 gallons for one betta unless you already want that room.
How to choose among these tanks
Run the Waterpuppy Footprint-Glass-Stand Check before you pay freight.
Use this three-part check.
- Footprint. Measure wall length and room depth. A 72.5-inch Aqueon needs a 6-foot wall, and a 47.3-inch lagoon needs 35.4 inches of depth.
- Glass. Decide if you need a factory overflow. Reef-Ready and the rimless tanks are built for sumps, while the Standard 150 is a closed glass box.
- Stand. Use Aqueon’s 10-pound-per-gallon rule and budget about 1,500 pounds on the stand top.
If the wall is under 6 feet, skip the long Aqueon. If the room is less than 36 inches deep, skip the lagoon.
If you need a sump and want Aqueon glass, use the Reef-Ready 150 Gallon Rectangle.
If you want the stand in the same order, use the Innovative Marine or Acrylic Pros listing.
FAQ
These answers use the same maker numbers as the sections above and stay on 150-gallon tanks.
How much does a 150-gallon fish tank weigh?
Aqueon’s FAQ says filled aquariums weigh about 10 pounds per gallon, which puts a filled 150-gallon setup near 1,500 pounds. A 20-gallon example on the same page is about 200 pounds. Empty glass weight is not listed on that FAQ page.
What are the dimensions of a 150-gallon fish tank?
There is more than one shape. Rockland Aquarium lists the Aqueon Standard 150 at 72.5 by 18.5 by 29.5 inches. Innovative Marine lists the INT 150 Lagoon at 47.3 by 35.4 by 19.7 inches. Acrylic Pros lists the Reef Pro 150 Tall at 48 by 24 by 30 inches.
Can I put a 150-gallon tank on a dresser?
No. Aqueon’s FAQ says most household furniture will likely only support aquariums of 5 gallons or less. Use a stand made for a filled aquarium.
What filter do I need for a 150-gallon tank?
Aqueon’s FAQ says to pick a filter rated one size larger than the tank. A canister is the usual match at this volume. See our 75-gallon canister filter guide for how those ratings are written, then size up.
How long should I cycle a 150-gallon tank?
Aqueon’s FAQ says wait at least 48 to 72 hours after setup before the first fish. The nitrogen cycle still has to finish after that. Follow how long to cycle a fish tank and test ammonia and nitrite before you stock.
Does a betta need a 150-gallon tank?
No. Aqueon’s FAQ says bettas thrive from 76°F to 85°F, and they do not need 150 gallons. See what size tank a betta needs if that is your fish. Use a 150-gallon tank for a community, a goldfish group, or a reef plan that needs the volume.
Do I need a stand sold with the tank?
You need a stand rated for the filled load, but you do not need the stand to ship in the same box. Aqueon’s Standard 150 listing does not include a stand. The Innovative Marine and Acrylic Pros listings we read do include a stand or cabinet.
