Our take
Coralife's Size 16 BioCube has stronger base-model documentation than the frozen bundle title alone provides. Its manual identifies glass construction, item 100115661, a 16-gallon model size, 15 × 16.75 × 17.5-inch dimensions, a 185-gph pump, and a rear wet/dry filtration section. The manufacturer also describes a hood with timed LED channels. The frozen source row calls its seller package a six-item Deluxe Reef bundle, but the saved maker evidence does not identify that bundle or its extra contents. Compare the documented base system and verify the specific box before purchase.
A buyer wanting a compact glass aquarium with maker-documented rear filtration and integrated timed lighting, after checking the exact seller package..
Not for someone who needs the six-item bundle contents, a current exact Amazon variant, a sump rather than a rear chamber, or proof of lighting performance for a particular coral plan.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The maker manual gives an item number, UPC, glass construction, dimensions, and a 185-gph pump figure.
- A built-in wet/dry rear chamber and listed media parts provide a defined filtration layout.
- The maker page documents a hood with a 24-hour timer and three independent LED channels.
- The base model is distinct from the separately documented Size 32 BioCube.
What to weigh up
- The historical six-item bundle and any stand or extra accessories are not mapped to item 100115661.
- The rear wet/dry chamber is not a separately listed sump system.
- Fish, corals, substrate and décor are stated by Coralife as sold separately.

What the features mean for you
Separate the maker model from the frozen bundle
Coralife's product page links a Size 16 manual and lists item 100115661 with UPC 096316156616. The manual identifies the same item and shows a glass aquarium, canopy, feeding door, cooling fan, filter components, pump, and timed lighting parts. This evidence supports a specific maker base model. The source row, however, describes a Deluxe Reef Aquarium Bundle with six items. It does not provide a trustworthy package list that connects those six items to maker item 100115661. Keep the bundle language visible as a seller-package clue and confirm the current offer's exact item number and box contents before treating it as a complete reef setup.
Use the dimensions to plan a compact footprint
The manual lists the Size 16 tank at 15 inches long by 16.75 inches wide by 17.5 inches high. Those outside dimensions are more useful for a location check than capacity alone, although they do not include extra room for cords, ventilation, opening the hood, or maintenance access. The 16-gallon size is a nominal class, not a measured operating volume after substrate and equipment. Coralife's safety guidance says to use a flat, level location that supports the filled aquarium and to avoid direct sun and nearby heating or cooling vents. Confirm the support surface and service clearance for the actual setup.
Understand the rear filtration arrangement
The maker manual calls the rear assembly a wet/dry filter section and identifies a cartridge, overflow tray, media tray, sponge filter, pump, and discharge nozzle. It lists the pump at 185 gallons per hour. That makes the filtration layout more specific than a bare tank whose source does not itemize equipment. It remains an integrated rear chamber, not a separate sump that sits below the aquarium. The manual also describes adding biological or chemical media and offers a refugium arrangement, but that does not prove the frozen six-item seller package includes additional media or livestock. Ask which parts ship with the current offer and how replacement cartridges are selected.
Read the LED and timer claims carefully
Coralife describes a low-profile hood with LED lighting, three independent channels, a 24-hour timer, and automated sunrise/sunset and moonrise/moonset transitions. These controls let a buyer compare the base Size 16 with simpler tanks whose saved sources do not document a timed light. The manufacturer presents the LEDs for coral and plant growth, but the cited page is not an independent lighting test and does not establish that every coral type will thrive. The manual's listed PAR is a maker measurement under a stated test area and distance, not a guarantee of results in a filled aquarium. Confirm that the exact seller package includes this hood and controller revision.
Choose the system only after checking the box list
The Size 16 sits between smaller desktop models and Coralife's separately documented Size 32. It may suit someone who wants a glass tank with an integrated rear filter and timed hood in one base model. A buyer seeking a separate sump should compare listings that explicitly name one; the BioCube chamber is not counted as a sump in this guide. Coralife states that fish, corals, substrate, and décor are sold separately. No source here proves that the frozen six-item bundle adds a stand, heater, protein skimmer, or particular consumables. Match item 100115661 and UPC 096316156616, then ask for the exact included-parts list.
What else to compare
Coralife's BioCube Size 32 is a larger model in the same maker family and has its own manual and package evidence. For a glass model with a named separate sump, compare the Seapora Reef-Ready 56219 only after confirming its plumbing details; its catalog does not document a sump package.
Before you buy
What does the maker list for the Size 16?
Coralife's manual identifies item 100115661 / UPC 096316156616, 15 × 16.75 × 17.5-inch dimensions, and a 185-gph pump. The model size is 16 gallons.
Is its rear filtration a sump?
No cited maker source identifies a separate sump. The manual describes an integrated rear wet/dry filter section.
Does the exact frozen six-item bundle include a stand or skimmer?
The saved maker sources do not verify the frozen seller's six-item package or its extras. Confirm the current seller box list.
Is the lighting an independently tested coral-growth guarantee?
No. Coralife describes the LED and timer features, but the cited product sources do not provide independent performance testing for a specific livestock setup.
Why is the Amazon destination a search?
The historical ASIN has not been mapped to a current exact Size 16 offer. The search is tagged and names maker item 100115661 for comparison.

The decision
The base BioCube Size 16 is a documented 16-gallon glass all-in-one with an integrated wet/dry chamber, pump, hood, and timed LED controls. The historic six-item bundle remains unresolved, as does its Amazon mapping. Confirm item 100115661 and the current seller's box list before assuming the bundle includes extras or choosing equipment around it.
