Our take
The JBJ Nano 180 MT-302 is a compact, curved-front glass aquarium system with more specific documented equipment than a bare tank listing. The archived JBJ-USA owner manual calls it an 8-gallon model and describes a 180-degree panoramic view, three-stage top filtration, a 77-gallon-per-hour pump and an 11-watt daylight compact fluorescent lamp. Those details make it possible to compare the design and original configuration. The manual is historical documentation, however, and the current condition, package and Amazon offer are not confirmed. Treat this as a model to investigate rather than a verified current ready-to-run kit.
A shopper comparing a nominal eight-gallon curved-front glass system who can confirm the exact model condition, package and replacement parts before purchase..
It does not meet the finder’s about-ten-gallon minimum. It is also not a documented sump system, and the evidence does not establish current condition, replacement-part availability, a heater or stand, or a lighting solution for specialized plants or reef use.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The JBJ-USA manual identifies a distinct MT-302 model and an 8-gallon nominal class.
- The manual describes curved glass, 180-degree viewing, an integrated top filter and a 77 GPH pump.
- The original lighting and filter-media arrangement are documented more clearly than for several bare-tank profiles.
What to weigh up
- Eight nominal gallons is below the finder’s ten-gallon minimum and is not a measured usable-water volume.
- The 11-watt daylight compact fluorescent lamp is an older design; the manual does not establish current parts availability or lighting performance for a particular setup.
- A historical product mirror repeats the old ASIN, but no current exact Amazon offer or present-day package is verified.

What the features mean for you
Confirm the Nano 180 model identity
The archived owner manual is headed for the JBJ 8g Nano 180 and its specification block names model MT-302 and item number MT-302. Its exploded parts view labels the glass tank, frame, canopy, lamp, filter housing, pump and media baskets. A third-party mirror carries the frozen Half Moon Biotope Nano 180 title and repeats historical ASIN B00282I6HC, but that mirror is not a current Amazon product page and does not provide a present-day model crosswalk. The manual gives enough model-specific evidence to describe MT-302, while the affiliate destination remains a tagged search for the exact model rather than a direct ASIN claim.
Read eight gallons as a nominal class
JBJ describes the Nano 180 as an 8-gallon aquarium and gives dimensions of 15.03 × 10.12 × 18.62 inches. Those values are useful for a first capacity and space comparison, but they do not report measured operating water volume after substrate, decor or the chosen fill level. The current everyday and professional capacity question uses about ten gallons as its lowest hard minimum. The Nano 180 therefore drops out when that option is required; it remains in a flexible-capacity comparison. Do not round its eight-gallon class up to satisfy a ten-gallon requirement or use its manual dimensions without confirming the actual item and measuring the display location.
A curved front changes the presentation
The manual describes a glass aquarium with a curved, seamless front for a 180-degree panoramic view and a flat back intended for space-confining locations. This shape is the model’s clearest distinction from rectangular framed tanks and glass cubes in the current reviewed set. It is still a descriptive design feature, not a claim about optical distortion, glass thickness, impact resistance or long-term durability. The source dimensions can help start a comparison, but it does not establish a stand package or the safe load rating of a shelf or cabinet. Check the exact tank, its support surface and the available depth before planning a setup around the curved viewing panel.
The filter is a top-mounted three-stage arrangement
The manual describes mechanical filtration through fine filter floss, chemical filtration through an activated-carbon basket, and biological media in a ceramic-ring basket. It also identifies an integrated pump rated at 77 gallons per hour that sends water through an adjustable spray bar. This is a specific equipment layout and gives a buyer questions to ask about the exact package, filter replacements and pump condition. It is not a sump: the manual places the filtration housing above the water line within the top assembly. The finder leaves the sump answer separate, so a buyer who requires a listed sump will not be matched to MT-302. The manual’s flow figure is a manufacturer specification, not a verified present-day performance measurement.
Lighting and heater details need context
JBJ’s manual specifies an 11-watt daylight compact fluorescent lamp and an electronic ballast in the canopy. It also gives a daylight color-temperature label of 10,000 K in its lamp table. This identifies the original lamp type, but does not establish present availability, output at the water surface, timer functions, or suitability for any particular plant or animal. The manual includes a slot for a submersible heater and explicitly says that heater is not included. Because the evidence is an older owner manual, ask a seller to identify the actual lamp, ballast, heater and power components in the offered unit instead of assuming every original part is present or working.
Verify the item condition and package
The manual discusses using a level surface that can support a filled aquarium and warns against moving the tank while full or partly full. It shows separate instructions for a Nano 180 stand but does not establish that a stand is included with the aquarium. It likewise does not give a current box list from an active seller. The historical source record is from 2023 Amazon data; that roster is not a current stock or condition report. Confirm the MT-302 label, tank completeness, lamp and ballast condition, pump operation, filter pieces, heater status and support needs with the seller before relying on the old specification sheet. No listing used here establishes price, availability or warranty for a current offer.
Where it fits in the finder
With capacity flexible and glass selected, MT-302 belongs in a sourced comparison alongside UP Aqua UA-001B, All Glass Aquariums 158005, Aqua Japan AJ-40B, Seapora 59200 and Deep Blue Professional ADB11051. Its nominal eight gallons put it between the approximately two-gallon UP Aqua and nominal ten-gallon All Glass model by listed capacity, while its curved-front integrated design differs from their saved evidence. A ten-gallon minimum removes MT-302, and a sump-only answer also removes it because the documented system is a top filter. These outcomes follow from source values and the stated matcher rules; they are not rankings, fish-care judgments or claims that the smallest model is suitable for a particular animal.
What else to compare
For a smaller glass option, UP Aqua UA-001B is listed at approximately two gallons with low-iron glass and a blue silicone edge, though dimensions and equipment are unresolved. All Glass Aquariums model 158005 is listed at ten gallons and as black glass, placing it at the current finder’s minimum rather than below it. Both use different shapes and have different source gaps; compare exact outside dimensions and package evidence before choosing between them.
Before you buy
What is the capacity and model number?
The JBJ-USA owner manual identifies the Nano 180 as model MT-302 and describes it as an 8-gallon aquarium. The capacity is a nominal manual value, not a measured operating volume.
Does MT-302 have a sump?
No sump is identified. The manual describes a three-stage filter housing in the top assembly, with floss, activated carbon and ceramic rings.
Is a heater included?
The manual shows a heater slot and says a submersible heater is not included. It does not prove what a current or used seller package contains, so confirm the exact offer.
Is ASIN B00282I6HC a current exact Amazon listing?
That ASIN appears in a third-party mirror of the frozen product title, but no current exact Amazon offer was verified. The affiliate destination is a tagged search for Nano 180 MT-302.
Where can I check the current price?

The decision
JBJ Nano 180 MT-302 is a source-documented 8-gallon curved glass aquarium system with an original three-stage top filter, 77 GPH pump and 11-watt daylight CFL. It is excluded by the ten-gallon minimum and is not a sump system. The manual supports model facts, not a current Amazon offer or a guarantee about a seller’s package or condition. Use the tagged exact-model search and confirm the MT-302 label and all included parts before buying.
