Disclosures

Current state (phase 1)

As of launch, FishTankMath ships with no affiliate links and no display ads. The site is in phase 1 of its content plan, which is calculator-led trust building before any monetization activates.

Future affiliate relationships

Once equipment buying guides ship in phase 2, the following affiliate relationships may activate as contextual references inside sourced editorial:

• Chewy via the Impact affiliate network. Pays ~4% commission on qualifying purchases. Used for aquarium equipment (filters, heaters, lighting, substrate, test kits). Not used for live fish or live plants.
• Amazon Associates. Pays 1–3% on pet/aquarium category purchases. Used as a fallback when Chewy doesn't carry an item.

Affiliate links, when they appear, will be marked as such in context. They never appear as the primary framing of a page, never as “best of” listicles, and never on water- chemistry or species-care pages where the editorial trust bar is highest.

Display advertising

Display ads (Google AdSense or equivalent) may appear on the site starting in phase 2. When they do, they will be:

• Placed at end-of-article, not inline-disrupting body copy.
• Not interstitial. Not popunder. Not autoplay video.
• Not used to sell sponsored content; ads are programmatic and independent of editorial.

Editorial independence

Affiliate or advertising relationships do not influence which products are mentioned, which sources are cited, or which recommendations are made. Sourced editorial decisions come first; monetization placements come after, only where they fit contextually.
