How we cover aquarium products
Every product on this site is evaluated with the same priorities a fishkeeper cares about: does it work reliably, is it good value, and will it keep your fish healthy? We look at build quality, ease of maintenance, noise levels, and how well a product performs over months of use rather than just out of the box. Where relevant, we include price ranges so you can compare options at a glance.
Guides vs product pages
Guides cover a whole product type - what it does, how different options compare, and what matters most when choosing. Product pages focus on a single item with detailed specifications, pros, cons, and where to buy. Both are written from hands-on experience.
Affiliate links
Some product pages include links to retailers. These are affiliate links, which means we may earn a small commission if you buy through them. This does not affect the price you pay or our editorial independence. We only link to products we genuinely recommend.
