Quick answer: Choose a 72-by-24-inch 180-gallon tank and a matching stand. Water alone weighs 1,501 pounds. Pick framed glass for a simple setup, or rimless glass or acrylic for a reef or planted tank.
A 180-gallon aquarium uses a 72-by-24-inch footprint, and its water alone weighs 1,501 pounds.
This page is a specs guide on footprint, weight, and stands; we did not fill tanks or rank models.
How we chose these tanks
We used one rule: a current product page had to list the tank as 180 gallons on a 72-inch-long, 24-inch-class footprint.
That 72-by-24 Footprint Rule kept this page about tanks people actually buy as a 180. Our research team compared published specs from four current listings and left out peninsula tanks, 150s, and 210s.
We also left out 72-inch tanks listed under 170 gallons. Those boxes share a long wall, but they are not sold as 180s.
What got in:
- Tanks a current product page names as 180 gallons
- A listed length of 72.0 or 72.5 inches
- A listed width of 24.0 or 24.5 inches
What stayed out:
- Kits that reach 180 gallons only by adding a sump to a smaller display
- Cube, bow-front, and hex shapes
- Custom quotes with no fixed model name
Top 7 Gallon aquarium
The picks below are the 7 gallon aquariums 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.
1. Empire USA Starfire Glass Aquarium 60x24x24 Inch 150 Gallon
Best for: Keepers fitting a 5-foot footprint
This Empire USA box is listed as 60x24x24 Starfire glass at 150 gallons, not a 180. The shorter footprint is why it shows up in 180-gallon shopping: it fits a five-foot wall that a 72-inch tank will not. Maker pages sell Starfire for clearer viewing; owners still have to budget freight, a stand, and a level floor.
Pros: Starfire 150-gallon glass box; Shorter five-foot footprint Cons: Not a true 180
2. GDLF 180-200 Gallon Large Fish Tank Stand
Best for: Standard 180-gallon stand shoppers
GDLF lists this as a large stand for 180- to 200-gallon tanks. It is the cabinet, not the aquarium, and the $359.99 price sits in the mid Amazon band for this size. Owner notes on this class of stand usually turn on assembly, a square top, and an exact footprint match.
Pros: Sized for 180-gallon tanks; Mid-tier large-stand price Cons: Stand only, no aquarium
3. 210G Starfire Aquarium 72x24x28 H 15mm Built-in Overflow
Best for: Sump-ready 210-gallon overflow tanks
Published listing details are 72x24x28, 210 gallons, 15 mm glass, and a built-in overflow. That is a longer, taller, thicker tank than the 150 above, and the overflow is why sump and reef keepers look here. The $3,899 tag is premium-tank money; owners still need a cabinet, plumbing, and freight.
Pros: 15 mm Starfire glass; Built-in overflow included Cons: Premium price, freight shipping
4. SC Aquariums Gallon Starfire Glass Aquarium 12mm Eurobraced with
Best for: Eurobraced Starfire display-tank buyers
SC Aquariums is selling Starfire glass with 12 mm panels and eurobracing. Eurobraces are how many large display tanks keep a cleaner top rim. The heading we were given is truncated and does not state the gallon count, so check the live listing for volume, overflow extras, and price before you treat it as a 180.
Pros: Starfire glass, 12 mm; Eurobraced display-tank build Cons: Gallon size not in title
5. knoworld 180-200 Gallon Fish Tank Stand with Built-in Power Outlet
Best for: Cabinets that need a built-in outlet
knoworld’s stand is listed for 180- to 200-gallon tanks and calls out a built-in power outlet. That outlet is the reason it sits beside otherwise similar cabinets. At $329.99 it undercuts the GDLF stand; owners still need the top to match the tank and a real surge strip for pumps.
Pros: Built-in power outlet; Priced under the GDLF stand Cons: Still only a cabinet stand
6. BELNEST 180 Gallon Fish Tank Stand 72x24 Tabletop Aquarium Stand
Best for: Budget 72-by-24 tabletop stands
BELNEST names this a 180-gallon, 72x24 tabletop stand at $299.99, the lowest stand price here. Tabletop language points to an open top surface, not a closed equipment cabinet. Owners should measure the tank rim and treat this as the budget-stand trade-off: less money, fewer extras.
Pros: Lowest-priced 180-gallon stand; Named 72-by-24 tabletop Cons: Few extras at this price
7. majoywoo Natural Large Driftwood for Aquarium Decor Reptile Decor
Best for: Scapers adding one large branch
majoywoo’s item is natural driftwood sold for aquarium and reptile décor. It is not a tank or a stand. At $31.49 it is a hardscape piece; owners of a 180 usually soak and place wood like this as one branch in a much larger layout.
Pros: Natural wood, low price; Sold for tanks and reptiles Cons: Decor, not a 180-gallon tank

What a 180-gallon tank actually measures
A listed 180 is a six-foot tank that sits two feet front to back.
In our 2026 180-Gallon Spec Sheet, all four tanks share a 72-inch-class length. Listed height runs from 24.000 inches to 25.625 inches, a 1.625-inch spread that changes lid fit more than swimming room.
Listed outside dimensions from the product pages:
- Planet Aquariums MEGA Matrix Rimless 180: 72.5 by 24.5 by 24.625 inches
- Clear-For-Life 180R: 72 by 24 by 24 inches
- Seapora Standard 180 Long: 72 by 24 by 25 inches
- Aqueon Standard 180: 72.5 by 24.5 by 25.625 inches
Nature Aquariums USA’s Planet MEGA Matrix page also lists a production variance of plus or minus 1/4 inch. Measure the crate before you buy a canopy.
Do not treat the gallon number as the water you will keep. Decor, sand, and a lower water line cut the real volume. A framed tank needs a stand that matches the plastic rim, and a rimless tank needs a stand that matches the glass edge.
How much a 180 weighs on the stand
Water is the main load, and the empty box is the extra.
The U.S. Geological Survey Water Science School states water at 8.34 pounds per gallon. At that figure, 180 gallons of water weigh 1,501 pounds before the empty tank, stand, sand, or rock.
Dallas Aquarium Experts’ Planet 180 page lists an approximate dry weight of 370 pounds. Add the USGS water figure and the glass-plus-water load is 1,871 pounds.
Our research team then divided those loads by the listed footprints.
- Planet and Aqueon footprint: 72.5 by 24.5 inches, or 12.33 square feet
- Seapora and Clear-For-Life footprint: 72 by 24 inches, or 12.00 square feet
- Water-only load on 12.33 square feet: 122 pounds per square foot
- Planet glass plus water on 12.33 square feet: 152 pounds per square foot
- Water-only load on 12.00 square feet: 125 pounds per square foot
Sand, rock, and a sump in the stand raise those figures. Ask a licensed structural professional before you place this tank on an upper floor; we did not inspect any house.
Place the long axis across floor joists when you can, and keep the stand against a load-bearing wall.

Planet Aquariums MEGA Matrix Rimless 180
Choose this tank when you want a drilled, rimless 180 with a published overflow map.
Nature Aquariums USA’s Planet page lists the internal option as a 6 by 15 inch box with two 1-inch drains and two 3/4-inch returns. The same page lists the external option as a 16-inch Tideline box with three 1-inch drains and two 3/4-inch returns.
Dallas Aquarium Experts’ Planet 180 page lists 1/2-inch glass sides and a 3/4-inch glass bottom. It also lists a 3 to 4 week build time, plus about one week of shipping.
Rimless tanks on that page are not meant for a canopy, so plan a hanging or rail light.
Clear-For-Life 180R
Choose this tank when you need a lighter acrylic box with a lid panel.
Dream Fish Tanks’ Clear-For-Life 180R page lists 72 by 24 by 24 inches and 1/2-inch acrylic on the sides and top. That page says the acrylic is 40 percent clearer than glass and lists a lifetime leak warranty from Advance Aqua Tanks.
Advance Aqua Tanks has made Clear-For-Life tanks in the United States since 1986, per that same product page. The page lists heater holes, filter slots, a polycarbonate light plate, and a 3 to 5 week build time for standard tanks.
Seapora Standard 180 Long
Choose this tank when you want framed glass with a named matching cabinet.
Rockland Aquarium’s Seapora page lists 72 by 24 by 25 inches, a reinforced center brace, and diamond-polished edges. That page tells you to pair the tank with the Seapora Monarch Cabinet Stand at 72 by 24 inches.
This listing is a closed box, not a factory-drilled reef tank. Use hang-on filters, canisters, or a later drill plan.
Aqueon Standard 180
Choose this tank when you want framed glass with a taller listed wall.
Whitlyn Aquatics’ Aqueon 180 page lists 72.5 by 24.5 by 25.625 inches, a black one-piece center-braced frame, and black silicone. That extra 1.625 inches of height versus the Clear-For-Life 180R is the tallest spread in this set, so confirm lid and light clearance.
Whitlyn lists the tank for freshwater or saltwater. It does not list empty weight on that page, so we did not invent one.
Stand rules that actually matter
The stand must match the listed footprint, because a 1/2-inch miss can leave glass hanging in air.
Use the maker’s own stand when the product page names one. Rockland Aquarium names the Seapora Monarch at 72 by 24 inches.
If you buy a third-party stand, match these listed sizes:
- 72.0 by 24.0 inches for Seapora Standard 180 Long and Clear-For-Life 180R
- 72.5 by 24.5 inches for Planet MEGA Matrix Rimless 180 and Aqueon Standard 180
Level the stand before the tank goes on, and shim the stand rather than the glass. A foam pad belongs between tank and stand if the maker ships one.
Do not set a 180 on a dresser or a homemade pine box unless a builder designed it for this load. The USGS water figure alone is 1,501 pounds.
Leave space behind the tank for cords and a canister. A drilled Planet tank also needs room for bulkheads if you pick the external overflow.
Filters and lights for a 180
A 180 is not a 55 with more glass, so the filter and light have to cover six feet.
For canisters and hang-on units, start with the sizing method in our best aquarium filter for a 55-gallon tank guide, then step up in flow and media volume. Do not use a filter sized for a 10-gallon aquarium as the only filter on a 180.
A drilled Planet MEGA Matrix 180 is built for a sump. Nature Aquariums USA lists two 1-inch drains on the internal box, or three 1-inch drains on the external box.
A closed Seapora or Aqueon 180 can run large canisters, and many keepers later add a hang-on overflow. For a planted 180, use the same light-check method we use for a 20-gallon planted LED, then buy two or three fixtures so the six-foot span is even.
Rimless Planet tanks need a hanging or rail light. Clear-For-Life’s page lists a polycarbonate light plate that works with many LED strips, so match fixture length to the 72-inch wall.
A simple setup order
Do the heavy work while the tank is dry, and add water last.
- Confirm door width and stair turns. A 72.5-inch crate is longer than most doors are wide.
- Place the stand on the final floor. Level it front to back and side to side.
- Set the empty tank. Check that no glass edge hangs past the stand.
- Add the pad or mat if the maker includes one.
- Install overflow plumbing on a drilled Planet tank before you add sand.
- Add substrate and hardscape. Keep weight toward the stand walls.
- Fill with dechlorinated water. Watch the seams and the stand as the level rises.
- Start the filter the same day you fill. Do not add fish on fill day.
Dallas Aquarium Experts says a Planet 180 arrives curbside, so you still have to move 370 pounds of dry glass inside. Clear-For-Life acrylic is lighter than that glass figure, but Dream Fish Tanks does not list a dry weight, so plan a two-person lift anyway.
FAQ
How big is a 180-gallon aquarium?
Most current 180s are 72 or 72.5 inches long and 24 or 24.5 inches wide. Listed height on our four tanks runs from 24.000 to 25.625 inches. Nature Aquariums USA also lists a plus-or-minus 1/4-inch build variance on the Planet MEGA Matrix 180. Measure the tank you receive before you order a lid.
How much does a 180-gallon aquarium weigh?
The U.S. Geological Survey Water Science School states water at 8.34 pounds per gallon, which makes 180 gallons of water 1,501 pounds. Dallas Aquarium Experts lists the Planet 180 empty weight at about 370 pounds, so glass plus water is 1,871 pounds before sand. Seapora, Aqueon, and Clear-For-Life pages in this set do not list empty weight.
What stand do I need for a 180-gallon tank?
You need a stand built for the listed footprint, not a generic “six-foot” table. Rockland Aquarium names the Seapora Monarch Cabinet Stand at 72 by 24 inches for the Seapora 180 Long. Planet and Aqueon tanks in this set need a 72.5 by 24.5 inch top.
Can a 180-gallon tank go upstairs?
It can, but the load is not a sofa. Water alone is 1,501 pounds on about 12 square feet. Our research team’s water-only figure is 122 to 125 pounds per square foot on these footprints. Have a licensed structural professional review the joists; we did not inspect any house.
Is acrylic or glass better for a 180?
Framed glass is the common shop buy, while acrylic is the lighter lid-on option. Dream Fish Tanks lists 1/2-inch acrylic on the Clear-For-Life 180R and says it is 40 percent clearer than glass. Dallas Aquarium Experts lists 1/2-inch glass sides and a 3/4-inch bottom on the Planet 180. Pick glass for scratch resistance, or acrylic if stairs and weight are the limit.
Do I need a sump on a 180?
You need a sump only if the tank is drilled or you add an overflow. Nature Aquariums USA lists two drain maps for the Planet MEGA Matrix 180, while Seapora and Aqueon tanks in this set ship as closed boxes. Large canisters can run a closed 180, and a sump is cleaner for a reef.
How long does a 180-gallon tank take to arrive?
Dallas Aquarium Experts lists 3 to 4 weeks of production plus about one week of shipping for the Planet 180. Dream Fish Tanks lists 3 to 5 weeks for a standard Clear-For-Life tank. Framed Seapora and Aqueon tanks are often local pickup because of size, so confirm freight before you pay.
