Everything here is documentary

A replacement relationship on this site records what a documentstates. It does not record a test. No filter, cartridge or media on this site was physically purchased, fitted, measured or run. Where a source gives a part number, a pack size or a model scope, that is reproduced; where it does not, the value is left explicitly unknown.

OEM and third-party information are kept separate

Two relationships that look similar can carry very different authority, so they are never shown as one thing.

OEM-listed replacement

The filter's own manufacturer — or a document that manufacturer publishes, such as an owner's manual or a product page — lists the replacement for that model. Example: a filter manual that prints “Model 200: Rite-Size C cartridge”.

Third-party compatibility claim

A seller, marketplace listing or other company states that a product is for that filter. Useful, but it is that company's claim. A third-party claim is never presented as an OEM endorsement, and the two are never merged.

Comparisons this site deliberately does not make

  • Similar or matching dimensions are not treated as a guaranteed fit.
  • A seller's “compatible with” is not upgraded to manufacturer approval.
  • Physically fitting is not treated as equal filtration performance.
  • No claim is made about biological capacity, chemical performance, flow, lifespan or quality equivalence between an OEM part and any other part.

How sources are chosen and recorded

Preferred sources, in order: the manufacturer's manual, the manufacturer's product or support pages, its parts catalog, then third-party manufacturers, then retailers. Every published relationship keeps its source URL, the type of document, who published it, the quoted evidence used, and the date it was retrieved. Where the manufacturer's live page could not be reached, an Internet Archive snapshot is used and labelled as such.

Where a source was missing, inaccessible, or simply does not publish a value, the value is recorded as unknown — never as zero, never as “not compatible”, and never as an estimate.

Scope

This reference covers freshwater aquarium filters sold in the United States, with English-language sources and the Amazon.com (US)ecosystem in mind. Prices, stock and availability are not tracked here.

Corrections

A reference like this is only as good as its sources. If a manufacturer has changed a part number, or a mapping here does not match the document it cites, the correction should be made against the source — the dataset keeps the source URL precisely so that a claim can be re-checked, refreshed or withdrawn.

A dedicated public correction inbox is not configured yet. Corrections are reviewed against the cited source before the reference is changed.
