Our take
Marineland's Corner-Flo chart lists a black 125-gallon aquarium with two overflows under item 97011 and gives an approximate 72 × 18 × 22-inch size. A detailed chart copy identifies black-frame item 97011-01 and lists three glass-thickness fields along with no tempered panels. The frozen title names APF97011, while its separate structured model hint 308845 remains unexplained. The related APF97027 article covers the Oak finish in the same broad 125-gallon/two-overflow family; this black item remains a separate finish/code candidate, not a different filtration system. The historical Amazon ASIN is not verified as a current exact offer, and the source does not establish a seller's complete equipment package.

Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- The manufacturer identifies black item 97011 as a 125-gallon Corner-Flo aquarium with two overflows.
- The detailed chart copy provides a more specific size and glass-thickness fields for black item 97011-01.
- The black finish/code can be compared directly with Oak APF97027 without treating the two as the same offer.
What to weigh up
- The frozen structured model hint 308845 is not cross-referenced by the maker sources.
- Two overflows do not prove that a sump, pump, stand, light, or external filter is part of the current seller package.
- The official chart's rounded dimensions and detailed chart copy's fractional dimensions should be checked against the current item label.

What the features mean for you
Separate the black code from the Oak model
The frozen source title names a Marineland APF97011 aquarium in black. Marineland's Corner-Flo table lists black item 97011 at 125 gallons with two overflows, and an archived dealer post distinguishes APF97011 black from APF97027 Oak in the same family. The maker table gives an approximate 72 × 18 × 22-inch size. This establishes a meaningful finish and item-code difference from the already reviewed Oak variant, while the structured source field 308845 remains unexplained. Keep the two entries linked as related choices but do not merge their Amazon identity or assume that every included accessory is shared.
Use the dimensions as a model check
Marineland's simplified chart gives an approximate 72 × 18 × 22-inch footprint for the black 125-gallon item. The detailed chart copy identifies item 97011-01 and supplies fractional dimensions of 72-9/16 × 18-23/32 × 22-1/8 inches. Those values are close but differently reported; treat the fractions as a more detailed chart entry, not a guarantee that a seller's package or revision is identical. The length and depth can help compare this long layout with other 125-gallon profiles, but neither source supplies a stand rating or placement clearance. Confirm the current label and dimensional drawing before arranging support or plumbing access.
Read the glass fields with their model code
The detailed chart copy reports 10 mm and 10 mm glass thickness fields, a 6 mm field, black silicone and no tempered panels for item 97011-01. That is stronger construction detail than the simpler Corner-Flo size table provides. The product is therefore classified as glass for this black item because the detailed row identifies glass thickness. The maker materials do not authorize drilling or modification; if a setup plan depends on altering a panel, get written model-specific guidance. Do not automatically transfer the detailed thickness entry to Oak APF97027 unless its exact code row is independently supported. This keeps the black candidate's sourced attribute separate from the earlier product's explicit unknown.
Distinguish two overflows from a complete sump system
The manufacturer identifies two Corner-Flo overflows, which is a tank-layout fact relevant to a plumbing plan. The cited size table does not list a sump, return pump, cabinet, lighting, or a complete reef-system bundle for this specific historic candidate. Overflows provide a route for water movement but do not by themselves identify the rest of a filtration installation. This finder therefore leaves filtration unknown and does not include APF97011 in the sump-required answer. If the setup depends on a particular drain or return arrangement, request the current plumbing diagram and parts list for the exact item number rather than inferring the seller package from the Corner-Flo name.
Compare finish and evidence with APF97027 Oak
APF97027 is the Oak-finish model already described in this guide; APF97011 is the black code from the frozen title and manufacturer table. Both are presented as 125-gallon Corner-Flo aquariums with two overflows, so the clearest buyer-facing distinction is the finish/code and the fact that the black detailed chart copy supplies glass-thickness information. The old Oak article keeps construction unknown from its cited chart; this new evidence is not silently transferred across products. A shopper deciding between finishes should compare the current item number, frame appearance, dimensions, panel details and box contents, rather than assuming the only difference is cosmetic or that either includes a cabinet.
Verify the present listing instead of reusing the old ASIN
The historical Amazon title and ASIN are candidate clues, not a current offer crosswalk. The manufacturer model item number supports a black 125-gallon Corner-Flo family member, but the separate 308845 hint and present seller package remain unresolved. Search using APF97011 and 97011, then compare photographs and product documentation for the black frame, two overflows and exact dimensions. Confirm whether the offer is the aquarium alone or a package with separate equipment. The linked Amazon destination is a tagged exact-model search, not a direct historical ASIN link. This lets a shopper check current offers without the review claiming live stock, price, seller quality, or a bundle the sources do not document.
What else to compare
The existing Marineland APF97027 profile is the Oak-finish 125-gallon Corner-Flo choice, while this article covers the black item code. The two entries share a broad capacity and overflow class, but current package and precise model crosswalk should be confirmed individually. Red Sea REEFER 350 White has a documented catalog sump arrangement at a much smaller display size if a listed sump is essential; its historic seller revision also remains unresolved.
