Catalog scope
The catalog covers US freshwater equipment: filters, heaters, lights, water testing, conditioner, thermometers, water-change tools and backup air. It is a researched selection of exact models, not every product sold or a retailer inventory feed.
Fields and meaning
Records retain manufacturer/model identity, published electrical and size limits, capacity, separate flow measurements, included items, installation checks, routine work, unresolved facts and source links. Missing wattage or flow remains unknown and is not ranked as low consumption or low output.
Current source boundaries
The initial source check is September 7, 2026. Some manufacturers do not publish every dimension or electrical rating. Some sources differ by generation or publication date. Those gaps are visible in the individual record. Published light measurements do not establish output at an unstated depth.
Reuse and corrections
Product names and factual specifications identify their respective manufacturers. This local candidate does not expose a bulk download of licensed Amazon image metadata. To correct a record, use the contact page and include the exact model and manufacturer source.
