Source policy

We use exact manufacturer pages and instructions for product measurements, compatibility, test coverage and installation limits. Recognised aquatic care organisations help establish freshwater care practices.

Make the source fit the claim

A product page can establish what a kit includes. It cannot establish an independent accuracy comparison. A filter's stated upper tank rating cannot prove that the model suits every aquarium at that capacity. We keep those distinctions in view when writing recommendations.

Retail information

Retailer pages help identify a current purchase route. We do not copy review totals, star ratings or promotional prices into static articles. Product photographs in Amazon blocks are supplied by the authorised Amazon Creators API. Editorial images illustrate the subject.

Sources readers can follow

We link to the documentation supporting material claims. References identify the equipment and guidance behind our recommendations.
