Questions, corrections, and ideas for the aquarium knowledge base — we read every message.
The fastest way to reach us
Aquarium Knowledge is run by a small team of hobbyists, so email is the one channel we monitor. Write to us at:
hello@aquariumknowledge.comWe usually reply within a few days. Please include a link to the page you are writing about, if any.
What to write about
Anything related to the site or the hobby — these are the most common reasons people reach out.
Corrections
Found a wrong number, a typo, or an outdated recommendation? Tell us and we will fix it. Corrections to calculator math or wiki definitions get priority.
Tool feedback & requests
Is a calculator missing a shape or a unit you need? Want a stocking, dosing, or lighting calculator next? Feature requests shape the roadmap.
Article & wiki suggestions
Suggest topics for articles and wiki entries — species, equipment, techniques, or problems you could not find a clear answer for anywhere else.
General questions
Questions about the site, how we test gear we suggest, or how the knowledge base is built. We cannot diagnose or medicate sick fish by email, but we can point you to the right article.
A note on product suggestions
We do not accept paid placements, sponsored posts, or affiliate reviews. If you represent a brand, please know that any gear mentioned on Aquarium Knowledge is suggested only because hobbyists with 5+ years of experience bought it and tested it themselves. Press releases will not change what we recommend — but factual corrections about equipment specs are always welcome.
