Terms of Use
Last updated: June 24, 2026
These Terms of Use ("Terms") govern your use of mytanklogic.com (the "Site"), operated by Tank Logic ("we", "us", or "our"). By accessing or using the Site, you agree to these Terms. If you do not agree with them, please do not use the Site.
1. Use of the Site
Tank Logic is a free educational resource for aquarium hobbyists. You may use the Site and its tools for your own personal, non-commercial fishkeeping. You agree not to misuse the Site, attempt to disrupt or overload it, scrape it at scale, or use it in any way that breaks the law.
2. Educational Content — Not Professional Advice
Everything here is general information shared from hands-on hobbyist experience. It is not veterinary, medical, or professional advice. Living animals are unpredictable and local conditions vary enormously, so you are responsible for researching and making your own decisions about your tank and the animals in your care. When an animal is unwell, consult a qualified aquatic vet.
3. Calculators and Tools
Our calculators and planners produce close estimates to help you plan. They run entirely in your browser, and we never see or store the values you enter. Results are guidance, not guarantees — real-world figures depend on your equipment, livestock, plants, and how a tank is set up and maintained. Always treat the output as a starting point, not a final answer.
4. Intellectual Property
The original content on this Site — guides, calculators, text, and graphics — is the work of Tank Logic and is protected by copyright. You are welcome to read it, link to it, and reference it. You may not republish, copy wholesale, or sell our content as your own without permission. A short quote with a link back is always fine.
5. Third-Party Links and Advertising
The Site links to third-party websites and displays advertisements through Google AdSense. We do not control and are not responsible for the content, products, or practices of third-party sites or advertisers. Visiting them is at your own discretion. See our Privacy Policy for how advertising cookies are handled.
6. Disclaimer of Warranties
The Site is provided "as is" and "as available", without warranties of any kind, whether express or implied. We do not warrant that the Site will be uninterrupted or error-free, or that the information and calculations on it are complete or accurate for your specific situation.
7. Limitation of Liability
To the fullest extent permitted by law, Tank Logic will not be liable for any loss or damage — including the loss of livestock, plants, or equipment — arising from your use of the Site, its tools, or its guidance. You use the information here at your own risk.
8. Changes to These Terms
We may update these Terms from time to time. When we do, we will update the "Last updated" date at the top of this page. Continuing to use the Site after changes means you accept the updated Terms.
9. Governing Law
These Terms are governed by the laws of the jurisdiction in which the Site operator is based, without regard to conflict-of-law principles. Any disputes arising from them will be handled in the courts of that jurisdiction.
