Our take
Oceanic's product catalog identifies BioCube HQI Size 29 item 36015 and UPC 7 97926 36015 7. The matching owner manual documents a glass aquarium, 26-gallon net volume, three-chamber filter components, a protein skimmer, refugium parts and a 150-watt double-ended 14,000K metal-halide light. Legacy brand metadata conflicts with the Oceanic catalog. No source maps historical ASIN B0036ITD9M to a current exact Amazon offer, so verify the item number and UPC on any present-day listing.
A shopper comparing a catalog-identified glass BioCube with a source-documented rear filtration arrangement and metal-halide light, after confirming current condition and box contents..
It is not a confirmed choice for someone who needs a current verified offer, a 29-gallon net water volume, a separate sump, current replacement-part availability, or an itemized present-day seller package.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Oceanic's catalog gives item 36015 and a matching UPC for the BioCube HQI Size 29.
- The owner manual documents glass construction, a 26-gallon net volume and outside dimensions.
- The sources describe integrated rear filtration, protein-skimmer and refugium components, and a 150-watt HQI light.
What to weigh up
- The manual distinguishes a Size 29 aquarium from 26 gallons of net volume, so the two numbers should not be conflated.
- The 20 × 20.75 × 19.25-inch footprint requires more depth and width than a standard narrow rectangle.
- The historic manual and catalog do not establish current production, condition, exact seller package, or a current Amazon offer.

What the features mean for you
Resolve the identity against Oceanic's item number
The product name and model clue identify Oceanic 36015 BioCube HQI, while the catalog independently names BioCube HQI Size 29 item 36015 and prints UPC 7 97926 36015 7. The owner's manual separately identifies the BioCube HQI and its specifications. Legacy brand metadata conflicts with the Oceanic documentation, so a current offer should be checked by its item number and UPC. The available sources do not connect historical ASIN B0036ITD9M to a current Amazon product or seller package.
Keep the size label and net volume distinct
The manual describes a glass aquarium of Size 29 and separately lists net volume as 26 gallons. This review uses 29 as the model's source-listed size class for capacity matching, while preserving the 26-gallon net value in its description. Neither figure measures the filled operating water after substrate, equipment, or chosen fill level. The manual's outside dimensions are 20 by 20.75 by 19.25 inches, giving a boxier footprint than a narrow rectangular tank. Measure the intended space and confirm support requirements for the exact unit before selecting furniture.
A rear filtration system with several named parts
The manual's parts list names filtration covers, a filter cartridge, overflow tray, output elbow, flexible tubing, water pump, protein skimmer, refugium strainer, and sponge filter. Its filter-operation section describes water moving through three numbered chambers and returning through a discharge nozzle. That is a more detailed equipment record than a bare-tank listing. The manual does not state current media availability, present package condition, maintenance cost, noise, or measured filtration effectiveness. The finder records the integrated arrangement but does not call the rear chambers a separate sump.
The HQI lighting details are specific but historical
The owner manual lists a 150-watt, 14,000K, double-ended metal-halide lamp and also identifies 38-millimeter cooling fans at 4,000 RPM. Oceanic's catalog describes the HQI light as part of the BioCube system. Those specifications help distinguish this older configuration from the LED BioCube Size 32 reviewed elsewhere. They do not establish current lamp supply, electrical condition, light output at the water, replacement cost, or suitability for any particular plant, coral, or animal. A buyer considering an older unit should verify the actual included fixture, ballast, lamps, and operating condition directly with the seller.
Do not let the catalog package stand in for a current box
Oceanic's catalog copy describes a glass canopy, feeding rings, integrated filtration, protein skimmer, built-in refugium chamber, and 150-watt HQI lighting. The manual parts list provides further detail on the filter and skimmer components. These are useful historical package clues for comparing a complete system with a tank-only purchase. They do not prove that an old or current seller has every part, that components are in working condition, or that replacement components are included. Ask for a current itemized list and photographs of the item number before treating a search result as the exact kit.
How the model maps to the capacity and material answers
The sourced size-29 class and glass construction place Oceanic 36015 in flexible-capacity glass comparisons and in the about-ten-gallon-or-more glass paths. It falls below a hard fifty-gallon minimum and does not qualify for acrylic-only choices. Its rear integrated filter, protein skimmer, and refugium are named in the sources, but none identifies this model as a separate sump system, so the sump-required path excludes it. The sources do not establish finish or mounting format. The finder is comparing documented product structure, not claiming that the model is preferable for a particular animal or reef plan.
Use the search link to verify the exact historic model
The affiliate destination searches for Oceanic BioCube HQI Size 29 item 36015 because no source verifies the frozen ASIN as a current exact offer. Search results may show later BioCube products, replacement lights, stands, used units, or incomplete systems. Check for the Oceanic item number and UPC, then confirm the 20 by 20.75 by 19.25-inch dimensions, the 26-gallon net-volume note, and which filtration and lighting parts are present. Current price, stock, sales, warranty coverage, condition, buyer-review consensus, and personal testing are not established by the historical documents used here.
What else to compare
The reviewed Coralife LED BioCube Size 32 is a later model with its own manual and LED timer details; no successor relationship or package equivalence to Oceanic item 36015 is established. Compare the item number, lamp technology, dimensions, and current box contents rather than merging the two BioCube generations.
Before you buy
Is the Oceanic BioCube HQI 29 gallons or 26 gallons?
The manual calls it a Size 29 glass aquarium and separately lists a 26-gallon net volume. Keep the size class and net-volume figure distinct; neither is a measured filled operating volume.
Does the BioCube HQI have a sump?
The manual describes integrated rear chambers, a skimmer, refugium parts, pump and filter components. It does not identify a separate sump, so the finder does not count it as a sump-required system.
What lighting does item 36015 use?
The owner's manual lists a 150-watt, 14,000K double-ended metal-halide lamp and cooling fans. Confirm that the fixture and lamp are present and working in any specific offer.
Why is the Amazon destination a search link?
The historical ASIN is not verified as a current exact offer. The search names Oceanic BioCube HQI Size 29 and item 36015 so a shopper can check the listing identity and contents.
