How We Research
Reeflective — Aquarium And Fishkeeping Gear is a research and comparison site. Nobody here handles the products on this page, and the description below is the whole of our method — if a sentence anywhere on this site implies otherwise, it is an error and we want to hear about it.
What the comparison is built from. Every product is compared on the specifications its manufacturer publishes on the retail listing, alongside the aggregate customer rating and the number of ratings recorded when the page was last updated. Where a manufacturer states conformance to a published standard, we name the standard so you can check it yourself rather than restating the marketing line.
How products get onto the list. Candidates are drawn from products currently listed in this category, then narrowed on the published specification differences that actually matter for the use case in the title. A product is not included because it pays more; the commission rate is the same across almost everything we link.
What gets re-checked. Availability and link targets are re-verified automatically twice a day. Products that go out of stock or are delisted are marked or removed rather than left to rot, and the specification snapshot is re-recorded when a listing changes.
What we do not do. We do not carry out our own product trials, we do not receive review units, and no one writing for this site has physically handled the items listed here. Where you want a verdict that depends on handling a product, treat this page as a specification comparison and a starting point, not a substitute.
